OUTSTANDING STORM OF THE MONTH

Indiana Tornado Inflicts much Damage but Injures Zero – August 19, 2009

Strong to severe thunderstorms moved across parts of northwest Indiana during the late afternoon and evening hours of August 19th, producing one tornado in Chesterton. It first touched down in southern Chesterton east of 11th Street and southwest of South Park Drive. The tornado quickly intensified as it moved to the northeast and caused the partial collapse of a gymnasium roof at the Chesterton Junior High School. A wind gust to 105 mph was measured by an anemometer near the school. This damage along with numerous trees that were either uprooted or sheared off was caused by tornado winds reaching 110 mph. The tornado was rated EF1 at this point with a path width of 40 yards. BELOW: Roof blown off of a warehouse building down town Chesterton.

ABOVE: EF2 tornado confirmed in Chesterton IN.

The tornado continued to track to the northeast across the New York Central railroad tracks toward Grant Avenue where the roof of a warehouse had been peeled off and thrown about 15 yards behind the building to the north. The tornado continued to the northeast where an apartment building on Brown Avenue lost its entire roof. This damage was caused by tornado winds reaching 120 mph. The tornado damage was rated EF2 through this area with a path width of 60 yards.

BELOW: Roof blown off of apartment building on Brown Ave. In the city of Chesterton, 211 structures sustained damage; 8 were completely destroyed; 54 suffered major damage, such as trees falling through roofs. The remaining 149 structures sustained damage such as missing shingles or damaged gutters. Multiple vehicles were damaged by falling debris from buildings or trees. Numerous power lines were blown down along with utility poles blown down or snapped. This EF2 damage continued northeast where an entire field of healthy old hardwood tree trunks were snapped off or uprooted. The tornado then started to slightly weaken as it approached the Interstate 94 eastbound exit/westbound entrance ramps at Indiana Highway 49. A home south of the interstate had a garage roof blown off with still numerous trees uprooted or sheared off. Tornado wind speeds here were estimated at 100 mph with an EF1 rating. 4

Similar tree damage was noted along a path that continued to go to the northeast across Highway 49 and toward Highway 20 near Hadenfelt Road where some aluminum roofing material of a storage facility had been peeled off. Tornado wind speeds were estimated at 95 mph here and was rated EF1 with a path width of 30 yards. The tornado continued to move through a heavily forested area in the Indiana Dunes National Lakeshore, eventually crossing Highway 12. Radar imagery and an aerial survey suggest that the tornado dissipated north of the highway.

ABOVE: Numerous hard wood trees uprooted or snapped at trunk west of Calumet Rd.

While the area sustained tornado damage amounting to an estimated $1.5 million dollars, no weather-related deaths or injuries were reported anywhere in Porter County on the 19th.

LEFT: Tree damage leading up to the Hwy 49 exit ramps on Interstate 94.

AKZ222 Middle Tanana Valley 01 0001AKS 08 1100AKS 0 0 0.00K 0.00K Dense Smoke

Dense smoke was widespread in Fairbanks and North Pole on the morning of August 8, 2009, and the visibility was one quarter mile or less at the Fairbanks International Airport. Locally the visibility was reduced to only a couple hundred yards. The dense smoke was due to several large wildfires that were burning across interior Alaska. Although the smoke was dense on the morning of the 8th, areas of smoke reduced the visibility to one mile or less at times from August 1-7, 2009. The thick smoke brought air traffic in and out of Fairbanks to a standstill on August 5th, when most of the 30 plus flights that were scheduled to arrive or depart from Fairbanks International Airport were either cancelled or indefinitely delayed. The smoke resulted in very poor air quality, and at times, the air quality was above the hazardous level. The combination of a strong frontal passage and rain finally cleared out the smoke on the morning of the 9th. Several sports activities were cancelled during this time including a Senior Games tennis tournament and the High School Football Jamboree.

At this location, significant tree damage was observed with multiple limbs between one and two feet in diameter being broken and falling in a convergent manner. Also at this location, a detached garage was destroyed with debris being scattered 50 to 100 feet to the northeast. This appears to be the point along the damage path where the tornado reached its maximum intensity with an estimated peak wind speed of 105 mph and a width of 50 yards. The tornado then crossed County Road 2100 East causing damage to corn along both County Road 2100 East and County Road 2150 North. After crossing County Road 2150 North, the tornado destroyed a barn housing farming equipment, measuring 44 by 72 feet. Debris from this barn was scattered in all directions from the barn's original location. Several pieces of farm equipment estimated to weigh between 5,000 and 15,000 pounds were moved several feet north and northeast of their original location including a grain wagon which was lifted and placed on top of other farm equipment. After destroying the barn, the tornado moved northeast through a corn field where additional crop damage was observed. The tornado then again briefly lifted before striking a home and a detached garage along County Road 2340 East. Siding and minor roof and shingle damage was observed on the house and the detached garage lost its roof and suffered a collapse of the south wall. At this location, the tornado was estimated to be about 40 yards wide. The tornado appears to have lifted as it crossed County Road 2340 East.

Note: The estimated wind gust of 52 knots is equivalent to 60 mph. Gibson County Ft Branch 10 1515CST 1630CST 0 0 0.00K 0.00K Heavy Rain

A skywarn spotter reported 1.20 inches of rain in 30 minutes. This caused minor street flooding, and small streams topped their banks. A large cluster of thunderstorms sagged southeast into a region of relatively steep low level lapse rates where strong solar heating occurred. Moderately strong instability and ample low level moisture contributed to storm maintenance. A few of the stronger storms produced strong outflow winds. Heavy rain occurred due to the size and speed of the complex.

Pike County 1 NNW Petersburg 12 2200EST 14 0400EST 0 0 0.00K 10.00K Flood

At the Petersburg river gage, the White River crested at 16.19 feet. This is just above the flood stage of 16 feet. There was minor flooding of low-lying fields near the river, including some cropland.

Minor flooding occurred on parts of the White River. River flooding in August is very rare here. This was the first river flooding in August at Petersburg since 1979. The flood occurred because much of southeast Indiana was on the wet side following rainfall of 1 to 4 inches at the end of July. The same area and more were struck on August 4th. Without the rains at the end of July, the river flooding would not have occurred. Much of southeast Indiana received 2 to more than 12 inches of rain from the afternoon of July 29th through August 4th.

A weak cold front entered the state during night of the 2nd into the early morning hours of the 3rd. The airmass became unstable ahead of the front, though not as unstable as is typically the case in early August. CAPE values were in the 2000 to 4000 J/kg range with lifted indices around -6 C. Precipitable water values were generally three quarters of an inch to one inch. During the day temperatures warmed into the 80s with dew points generally in the upper 50s to mid 60s. Dew points pooled just ahead of the front and were between 65 and 70. The freezing level was quite high, between 14,500 and 15,000 feet. Thunderstorms developed over southeast South Dakota and northwest Iowa during the evening. They moved southeast and accelerated to around 50 MPH during the late night and early morning hours. Many of the storms produced hail, however hail was generally around an inch or less in diameter. One and one quarter inch diameter hail fell in Clarke County, northeast of Osceola. One of the stronger clusters of storms produced quarter to golf fall size hail in a swath from Schleswig to Denison in Crawford County. The hail stripped leaves from trees and caused extensive crop damage. Strong winds were produced as the storms moved into the northwest part of the Des Moines CWA. Considerable tree and power line damage occurred in Pocahontas, Humboldt, Webster, and Carroll Counties. Reports indicated that power was knocked out to about 10,000 homes. As the storms moved through Story County, lightning struck a house northeast of Nevada. A power pole was struck and the power line was on the house. A fire resulted causing some damage to the home.

High winds and small hail reported. A very warm, moist, and unstable airmass was in place over Iowa from 8th into the 9th. Surface temperatures on the 8th warmed into the upper 80s and 90s, with dew point readings in the 70s. A weak cold front moved into the state during the evening of the 8th and early morning of the 9th. There was little thunderstorm development initially as the airmass was capped. Temperatures at the 700 mb level were +14 to +17 C. During the early morning hours of the 9th, a short wave lifted northeast out of the southern Rockies. This resulted in cooling of the mid levels of the atmosphere, thus destabilizing the airmass. The cold front stall out during the morning of the 9th as a second short wave lifted northast. Eventually, the front moved south of the state on the night of the 9th. Overall lifted indices were in the -6 to -10 C range with CAPE values in the 3000 to 4000 J/kg range. Downdraft CAPE was in the 800 to 1400 J/kg range with 30 to 50 kts of shear available. CAOE available in the -10 to - 30 C layer of the atmosphere was between 300 and 700 J/kg, with a freezing level of 14,000 to 14,500 feet. The LCL was relatively high across the area ranging from just below 1000 meters to about 1250 meters. Plenty of moisture was available with precipitable water values between 1.75 and 2.25 inches. Thunderstorms developed initially over Nebraska and tracked east-northeast into Iowa shortly after sunrise. One supercell continued to track across the state and produced a swath of wind and hail damage from Sac County east to Black Hawk County. Additional thunderstorms formed along the cold frontal boundary by mid morning and progressed into the state. The storms remained below severe levels for several hours, but did become severe by mid afternoon. A broken like of storms formed with two primary areas tracking east across central and southern Iowa. These two areas featured mini bow echoes. The predominant mode of severe weather in the afternoon was high winds. Several of the storms produced hail, but the hail was sub-severe. A long lived supercell Thunderstorm tracked across northern Iowa Sunday morning with the Highway 20 corridor receiving the brunt of the damage. Reports of quarter to golf ball sized hail were common with some hail stones reported to be in excess of two inches approaching the size of a tennis ball. The hail was wind blown as well, at speeds of 50 to 70 mph, making it extremely damaging and dangerous striping siding off houses and knocking out windows. A measured wind speed of 68 mph was recorded at a KCCI TV SchoolNet site near Jewell in Hamilton County. Significant hail damage was received all along the track with areas near Otho, Callender, Radcliffe, Eldora and Grundy Center hit particularly hard. In Eldora, many homes had windows broken out and tree and power line damage left the city without power. Winds of over 100 MPH toppled a communication tower in Eldora. A short time before the winds hit Eldora, a 102 MPH wind gust was recorded at the landfill northwest of town. Wind driven hail of 2 to 3 inches in diameter broke all siding and windows out on the north and west walls of most homes, with hail stones reported landing inside of houses. Damage in the town of Eldora was expected to be greater than the damage done in the town of Parkersburg by the EF5 tornado a year earlier. A 150 square mile area of crops was affected in Hardin County. Total losses were reported on 45,000 acres, with 60% or greater loss on another 55,000 acres. Hail damage in the Otho to Callender areas was described as the worst seen in 20 years. MODIS satellite pictures of the crop damage area included in this report. Estimates of crop damage from this one supercell were over $175,000,000. Governor Culver declared Hardin County a state disaster area within a day or two of the storm, and declared Webster County a disaster area about a week later. Formal paperwork was turned in to make 8 Iowa counties federal disaster areas, They were Calhoun, Grundy, Hamilton, Hardin, Ida, Sac, Webster, and Woodbury. Following the storms, a shelter was set up for those who felt they should not stay in their homes. Luckily the evening round of storms tracked south. Campers at nearby Pine Lake State Park, gathered for an archery event, were bruised by hail. There were 22 reports of injuries in Hardin County, 11 serious enough for people to be taken to hospital, but there are no known life threatening injuries. A second round of severe weather rolled roughly along I-80 between 1630 and 1800 CST, producing a lot of tree and power line damage but apparently little structural damage. As the storms moved through the metropolitan Des Moines area, winds damaged power lines and knocked out power to 12,000 homes. One storm produced a wet microburst in Union County. The winds took the roof and shingles off of a two story brick building near Afton. The afternoon round of storms produced some hail, but most of the hail was not severe as mentioned above, and was pea size or smaller. During the morning round of storms, lightning struck a building in Waverly. The lightning struck an antenna on the building and melted screws all the way down the side of the building, starting a small fire and blowing hole in the wall. Note: The estimated wind gust of 52 knots is equivalent to 60 mph.

Grundy County 1 S Dike 10 1729CST 0 0 1.00K 5.00K Hail (1.00)

A weak convergence zone dropped southeast into Iowa during the afternoon. Residual moisture was enough for thunderstorms to develop. Lifted indices fell to -6 C, with CAPE around 2000 J/kg. The freezing level was around 13,000 feet. Several of the storms produced small hail and very heavy rainfall. One of them dropped quarter size hail in the Dike area. A few cold air funnel clouds were reported over eastern and southern Butler County as the storms receded.

IOWA, Central Cass County Atlantic 16 0325CST 0 0 200.00K 0.00K Thunderstorm Wind (65EG) An apparent microburst downed trees and branches in Atlantic through the center of town between 10th and 11th street. The damage path was about 3 blocks long. Whole trees were downed, up to 3 feet in diameter.

A cold front advanced into Iowa from the west during the early morning hours of the 16th. A line of thunderstorms formed ahead of the cold front in a low shear environment. In fact, only 20 kts or less of shear was available in the area and there was virtually no CAPE available. A mesoscale convective system from the west advanced into Iowa, fed on a 55 kt low level jet. The storms were weakening as they progressed eastward. One of them produced a microburst in the city of Atlantic in Cass County. A three block by one half block section in the center of the city between 10th and 11th street received damage. Numerous large trees were uprooted and branches up to 3 feet in diameter were broken. Winds were estimated at 75 MPH. No structures were damaged by the winds however. Note: The estimated wind gust of 65 knots is equivalent to 75 mph.

A strong cold front moved into Iowa during the afternoon of the 19th, and traversed the state during the night. The system was quite dynamic for mid August as the upper level low pressure closed off over Minnesota during the evening and a 70 kt jet was present at 300 mb. The atmosphere became unstable as afternoon readings reached the upper 70s to around 80, with dew points in the upper 60s. Instability was limited by the fact that there were two rounds of thunderstorms that crossed the state during the day, limiting the heating. None the less, lifted indices fell to around -8 C and between 2000 and 3000 J/kg of CAPE was available. Wind shear was around 45 kts in the near storm environment. The freezing level fell during the late afternoon and evening, and sloped from 13,500 feet over the east part of the CWA, to 12,500 over the west. A line of thunderstorms developed just ahead of the cold front. Most of the storms produced gusty winds and pea, to a little larger, size hail. A couple of the storms produced severe hail. One inch diameter hail fell from one of the storms south of Corning in Adams County. Another storm dropped one inch diameter hail east of Harcourt in Webster County. Wind gusts were generally in the 25 to 40 MPH range, with a few reports to around 45 MPH. Some of the higher gusts were in the Waterloo area, with a 56 MPH wind gust. Storms produced a 47 MPH wind gust in Windsor Heights.

Emergency Manager reported flash flooding at several locations over the southwest half of Wayne County between 2030 and 2400 CDT. Several roads were closed due to high water rushing bumper deep. Numerous basements were flooded in Corydon.

A cold frontal boundary dropped south into Iowa and stalled out just south of the state. Rounds of thunderstorms moved east- northeast across the state as a series of waves moved along the front. Heavy rainfall resulted during the early morning of the 26th, then again during the evening of the 26th into the morning of the 27th. A band of 3 to as much as 7 inches of rain fell from south central into east central Iowa. Conditions had been relatively dry prior to the rain and as a result, most of the flooding was limited to urban and small stream flooding. General flooding occurred in Tama County in several locations. Water was reported over both state and U.S. highways for several hours. Flash flooding occurred in Wayne County with several roads covered with water flowing car bumper deep. Reports from the county indicated that there was extensive road damage with at least 50 washouts.

For much of the year, precipitation was above normal across the southeast and below normal over the northwest. Very heavy rain fell from the 25 to 27th over southeastern Iowa, resulting in widespread flooding. Monthly precipitation totals varied from only 1.40 inches at Spencer to 14.44 inches at the Cedar Rapids Airport. The Cedar Rapids total broke their previous August record of 13.09 inches set in 1993. While southeastern Iowa is saturated, parts of northwest and north central Iowa are on the verge of drought conditions. Streamflows are below normal over some parts of the northwest but this summer"s cool weather has prevented significant crop impacts in that area. The most significant flooding was in the Promise City area in Wayne County. The South Fork of the Chariton River rose to nearly 6 feet over flood stage. For the most part, rises were just over flood stage across south central into southeast Iowa, limiting the damage to agricultural lands. Flooding on the South Fork of the Chariton River resulted in some minor flooding, but again, mostly agricultural.

LOUISIANA, Northwest

An upper ridge centered over west Texas and eastern New Mexico allowed for a disturbance to ride around the eastern/southeastern periphery and kick off showers and thunderstorms. The storms initially developed over extreme northeast Louisiana and propagated southwestward. They entered Ouachita, Caldwell, and LaSalle Parishes and continued west southwestward. A substantial cold pool developed and storms became linear (oriented N-S) and began riding the outflow, propagating due west. Storms moved across northwest Louisiana and into east Texas, producing wind damage along the line. This line of storms finally died over Rusk County in eastern Texas. One more storm developed in Angelina County along what appeared to be the outflow boundary, but died soon after sunset. Note: The estimated wind gust of 53 knots is equivalent to 61 mph.

Heavy rain producing thunderstorms caused flash flooding across some county roads from around Pierce to near Plainview. Besides washing the gravel off of a few county roads, some crops in low areas also sustained damage. Pierce had 4.13 inches from the storm with 4.18 inches reported several miles south of Plainview. The rain began falling during the late afternoon hours of the 15th and persisted a bit past midnight on the 16th.

Moist and unstable conditions that prevailed over eastern Nebraska during the afternoon and evening hours of August 15th helped set the stage for slow moving thunderstorms that repeatedly developed and tracked across parts of northeast Nebraska. The storms were aided by an unseasonably strong upper level system that was tracking along the Montana/Canadian border. The storms developed in a broken west to east line generally to the northwest through north of Columbus. The storms were eventually overtaken around midnight by a larger and generally north to south line of thunderstorms that had developed earlier that day over the western high plains. The storms in northeast Nebraska were mainly heavy rain producers, but a few possessed strong rotation and brought some hail and gusty winds.

An upper level disturbance working its way across the Plains worked in conjunction with a slow moving surface frontal boundary to produce thunderstorms across South Central Nebraska. With plenty of moisture available, these thunderstorms brought heavy rain to a good portion of the area, with Adams and Clay Counties the hardest hit. While anywhere from 2 to 4 inches were reported in portions of Hamilton, York, and Fillmore Counties, 3 to 5 inches fell in northern Adams and Clay Counties. The underpass in Hastings filled with water, with one motorists becoming stranded and needed rescue, and travelling on area county roads was difficult.

Hurricane Bill developed into a tropical depression over the eastern Atlantic on August 15, 2009. Bill then strengthened into a hurricane over the next week, passing well to the east of Nantucket, August 22-23. While Bill passed Southern New England well offshore, he still made quite an impression on the area. Tropical moisture feeding into the area resulted in heavy rainfall which led to flooding and flash flooding.

Hurricane Bill passed well east of the Mid Atlantic coast during the 22nd, while a cold front was approaching from the west. Swells from Hurricane Bill led to rough surf, moderate to severe erosion and numerous and strong rip currents from Friday the 21st through Monday the 24th. The worst conditions occurred on Saturday the 22nd as Bill made his closest pass to the region. Waves reached up to 10 feet along the coast and led to numerous water rescues, bathing restrictions and a few injuries. A 19- year-old surfer suffered a head injury on the 21st in Seaside Heights (Ocean County). A 23-year-old man was injured after being struck in the head by his surfboard on the 22nd in Ocean Grove (Monmouth County). Two other men fell off of their jet skis near Manasquan Inlet (Monmouth County) and had to be rescued by the Coast Guard. Many fishing trips were canceled and a longboard surfing contest was postponed until the following weekend in Long Beach Township (Ocean County). Bathing restrictions peaked on Saturday the 22nd, but some beaches were still closed on the 24th. The pounding surf caused beach erosion. The worst reported erosion was in Cape May County. In Monmouth, Ocean and Atlantic Counties, the vertical cuts were one foot to one and a half feet. In Cape May County, in Ocean City, near First Street, the erosion was described as severe as geotubes were exposed on Waverly Beach. A wash over occurred at North Street where the slope reached five feet. In Avalon, vertical cuts reached three to five feet on the north side of the borough. In Cape May City, a three to five foot cut in the dune occurred near Second Avenue. Other municipalities in the county reported vertical cuts that averaged one to two feet. No minor tidal flooding was reported along the coast due to increased seas, but the high tide reached underneath the Ocean City boardwalk on the 22nd.

Trees and wires were downed by thunderstorm winds. A massive convective complex moved from lower Michigan across southern Ontario near Toronto then dove southeast across the Niagara Frontier and Western Southern Tier. This followed an earlier round of strong thunderstorms and heavy rains earlier in the day. Damage from the thunderstorm winds was widespread across the Niagara Frontier and Western Southern Tier. Trees as large as two to three feet in diameter were downed. Power outages were scattered throughout the region as the winds downed power lines. The unprecedented heavy rains that fell"four to six inches in less than two hours"resulted in some of the worst flash flooding the area has seen. Parts of Erie, Chautauqua, Cattaraugus and Allegany counties received State and Federal Disaster Declarations. In the Village of Silver Creek an entire mobile home park along Silver Creek was washed away. The flood waters continued through the heart of the village through the fire station, police headquarters and highway department. Several police cars, an ambulance and much of the town"s highway equipment were lost. In Irving, the flood waters flowed across parts of the New York State Thruway and Routes 5 and 20. Water flooded portions of Lakeshore Hospital there. Also in Irving, the Seneca Nation sustained almost two million dollars in damage to roads and bridges. In total, in Chautauqua county hundreds of homes were damaged and 45 homes were condemned, including the 35 mobile homes of the aforementioned park. In the Village of Gowanda (part of which is in Erie County and part in Cattaraugus county), extensive flash flooding occurred. Tri-County hospital in Gowanda was inundated by flood waters. Patients were transferred to Lakeshore Hospital in Irving. Several hundred homes sustained damage and 40 homes were condemned there. One fatality occurred in Gowanda as an 80- year-old man ventured out to check a bridge on his property and was swept away by the flood waters. The gage on Cattaraugus Creek at Gowanda showed a rise from six feet to near 13 feet in less than an hour (flood stage is 10 feet). Throughout Cattaraugus county over one-quarter of the roads were damaged or lost. Note: The estimated wind gust of 50 knots is equivalent to 58 mph.

Thunderstorms developed during heating of the afternoon over parts of Southern Oklahoma. Temperatures reached into the 90s, making temperature-dew point spreads on the order of 30-40 degrees. Instability was minimal, but a few thunderstorms were able to produce very strong winds, causing some minor damage in Stephens county. At the same time, numerous thunderstorms developed ahead of a cold front that moved into northwest Oklahoma during the afternoon hours of the 26th. These thunderstorms developed through the evening hours, with the aid of convergence along the front, and lift associated with an upper level storm system moving through the central plains. The thunderstorms formed into several complexes due to the presence of numerous outflow boundaries. Surface moisture and instability along and just behind the front were sufficient for the thunderstorms to become severe. The thunderstorms moved off to the east with strong winds and large hail reported. A landspout developed over southwest Kingfisher county, remaining nearly stationary for over 10 minutes. No damage was reported with the landspout. Note: The measured wind gust of 63 knots is equivalent to 72 mph.

Hurricane Bill developed into a tropical depression over the eastern Atlantic on August 15, 2009. Bill then strengthened into a hurricane over the next week, passing well to the east of Nantucket, August 22-23. While Bill passed Southern New England well offshore, he still made quite an impression on the area. Tropical moisture feeding into the area resulted in heavy rainfall which led to flooding and flash flooding. High swells churned up by Bill resulted in high surf and coastal flooding along portions of the Southern New England shoreline. These effects were felt the most by residents of Hillsborough County, New Hampshire, where five inches of rain fell in less than eight hours resulting in significant flooding across portions of the county.

During August, extreme to exceptional drought conditions continued across South Texas. There was beneficial rainfall across southeast Webb County, Duval County, and Victoria County. Most locations outside of these areas received less than 25% of normal rainfall for the month of August. For the month of August the Corpus Christi International Airport only received 0.45 of rainfall, which was 13% of the normal rainfall for August. Victoria received 1.62 of rainfall, which was 53% of normal rainfall for August. The drought continued to have historic implications, with most of the region now in a 1-in-50 (some locations in a 1-in-100) year drought, rivaling the drought during the 1950s. The drought and lack of ground moisture also had impacts on summer temperatures. The Corpus Christi International Airport (CRP) broke the August record for the monthly average mean for daily average temperatures, and the Victoria Regional Airport (VCT) had its fifth warmest August on record. For the summer months of June through August, the Corpus Christi International Airport shattered the record for highest average maximum temperature by 2 degrees F, and also broke the record for average mean for daily average temperatures during this three month period. By the end of August, exceptional drought conditions were occurring across Victoria, Goliad, Calhoun, Refugio, Aransas, Bee, San Patricio, Nueces, Kleberg, Live Oak, Jim Wells, and Duval counties. Extreme drought conditions were observed across Webb, McMullen, and La Salle counties. (per the U.S. Drought Monitor: http://www.drought.unl.edu/dm/monitor.html) The agriculture industry in South Texas continued to be devastated through the month of August. Crops remained in very poor condition, and insurance companies were adjusting and paying farmers. For the first time in over a century, the historic South Texas drought claimed the entire cotton production of Kleberg County. Similarly, Nueces County had a 95% failure rate of cotton and San Patricio County had a 90% failure rate. For the entire state of Texas, crop and livestock losses from the drought were estimated at $3.6 billion, and predicted to surpass the $4 billion mark. Supplemental feeding of livestock with hay continued, however the condition of livestock overall remained poor due to little forage. Most surface water impoundments, creeks and storage reservoirs were dry, and livestock herds were either liquidated or being heavily fed. Periods of elevated to critical fire danger occurred through the month with sporadic wildfires observed. In addition, reservoir levels continued a gradual fall. Choke Canyon Reservoir was near 68% capacity and Lake Corpus Christi near 29% capacity by the end of the month. The City of Victoria continued mandatory water restrictions due to the drought conditions and low flow on the Guadalupe River.

Dry conditions and above normal temperatures at the end of July continued the first few days of August and maintained the end of July drought level intensities across Deep South Texas and the Rio Grande Valley. These values ranged from severe (D2) drought along the Rio Grande including most of Zapata County and a pocket in southeastern Hidalgo and Southwest Cameron County, to exceptional (D4) from the eastern half of Jim Hogg County through all of Brooks and Kenedy County, stretching south to Willacy County. By the end of the month, the drought would result of tens of millions of dollars in dryland crop, pastureland, and livestock loss across all of Deep South Texas.

Dry, record to near record heat, and frequently breezy to windy weather courtesy of persistent high pressure ridge above the surface extending from the southwest U.S. to the central Gulf of Mexico worsened the drought across Cameron and Hidalgo County through mid month. Drought conditions would reach their peak for the entire year for the final two weeks of August.

Continued record to near record heat, frequently breezy to windy conditions, low humidity for the time of year, and lack of rainfall allowed the 2009 Drought to peak before the end of August, ensuring massive dryland crop, pastureland, and livestock loss. The agricultural loss in the heart of Deep South Texas dryland crop country will be one of the worst in recent times. The pattern, featuring a persistent high pressure ridge above the surface from the southwest U.S. through the central Gulf of Mexico, would begin to break at month's end, but the rains were far too little, far too late, to save much of the crop yield.

A developing upper level low pressure trough in the mid and upper Mississippi Valley helped push a weak cool front into north central Texas on August 20 and 21. This front helped to increase compression - and heating - of the surface air mass across South Texas and Deep South Texas, while drawing up additional tropical moisture from the southeast. The result was two consecutive nights of widespread 80 or higher degree ambient temperature, along with a single day of afternoon heat index values which reached or exceeded 111 for 2 to 4 hours across much of the Rio Grande Valley.

CoCoRaHS observers reported between 2.5 and 3 inches of rain in both Palm Valley (about 2.2 miles west of Harlingen) and Rancho Viejo from a small thunderstorm complex which moved from Port Isabel west and developed stronger in west central Cameron County during the early afternoon of the 30th. Some poor draining streets had nuisance flooding, but most locations soaked up the rainfall, which was the first of significance during the entire month and going back to July 11th for most in the area. An unstable atmosphere, very weak upper level disturbance, a dissipating front north of the area, and the afternoon sea breeze helped trigger the first widespread rains in the Lower Rio Grande Valley during the month of August, on the penultimate day of the month. While the torrential rains were sucked up by very thirsty ground, a few areas saw nuisance poor drainage flooding with well over 2 inches falling in a short period of time during the early and mid afternoon.

A well organized tropical wave with an area of low pressure and significant thunderstorm activity moved offshore the African coastline on August 9th. The system moved northwest until reaching the southern Cape Verde Islands, then turned westward out into the open Atlantic. The system was upgraded to a tropical depression on August 11th, but easterly vertical wind shear kept the system from strengthening, and led to a reduction of thunderstorm activity which devolved the system into a remnant low pressure area on the 13th. By the 14th, the system redeveloped thunderstorm activity and redeveloped into a tropical depression, which strengthened into a tropical storm early on the 15th well to the east of the Lesser Antilles. Late on the 15th, a tropical storm watch was issued for the U.S. Virgin Islands, when the system was located about 910 miles east southeast of Saint Croix. At 5 am on the 16th, the tropical storm watch was extended to Puerto Rico, when the system was located about 850 miles southeast of San Juan. Soon afterwards, vertical wind shear from the west began to displace thunderstorms east and northeast of the center, beginning Ana's weakening trend. Also, the high pressure system steering Ana caused the system to accelerate westward. The weakening tropical storm Ana crossed the Lesser Antilles, and was downgraded to a tropical depression on the 16th at 5 pm, when it was located about 440 miles east southeast of Saint Croix. In spite of this, the tropical storm watch was kept in effect in case of any unexpected changes. Ana's local effects were mainly periods of heavy rain, gusty winds and cloud to ground lightning, and some much needed rain to Saint Croix. During the day on the 17th, aircraft reconnaissance determined that the system had dissipated southwest of Puerto Rico, as it no longer had a low-level circulation. At 5 pm on the 17th, the tropical storm watch was discontinued for the U.S. Virgin Islands and Puerto Rico.

Storm Data Disclosure

Storm Data is an official publication of the National Oceanic and Atmospheric Administration (NOAA) which documents the occurrence of storms and other significant weather phenomena having sufficient intensity to cause loss of life, injuries, significant property damage, and/or disruption to commerce. In addition, it is a partial record of other significant meteorological events, such as record maximum or minimum temperatures or precipitation that occurs in connection with another event.

Some of the information appearing in Storm Data may have been provided by or gathered from sources outside the National Weather Service (NWS), such as the media, law enforcement and/or other government agencies, private companies, individuals, etc. An effort is made to use the best available information, but because of time and resource constraints, information from these sources may be unverified by the NWS. Therefore, when using information from Storm Data, customers should be cautious as the NWS does not guarantee the accuracy or validity of the information. Further, when it is apparent information appearing in Storm Data originated from a source outside the National Weather Service (frequently credit is provided), Storm Data customers requiring additional information should contact that source directly. In most cases, NWS employees will not have the knowledge to respond to such requests. In cases of legal proceedings, under Department of Commerce regulations and/or rules of the court, NWS employees are not legally obligated to provide written or verbal testimony.

Fatality Codes: For events that include a fatality, there is a code containing the gender, age and fatality location at the end of the event narrative. 1st -letter: Gender (M/F) / 2nd -numbers: Age / 3rd -letters: Fatality location (see table below) Example: M51IW – Male, 51 years of age, fatality occurred In Water.

Other Notes:

An “Episode” is an entire storm system and can contain many different types of events.

An “Event” is an individual type of storm event.

When listing wind speed values under “Character of Storm”, i.e. High Wind (G81): The G indicates a “Gust” which is a peak 5-second averaged wind speed in Knots (kts). 1 kt. = 1.152 mph. This number can be either E (estimated) by damage caused, or M (measured) by known calibrated anemometers. Examples: (M61) = measured 61 knots; (E75) = estimated at 75 knots.

All wind speeds listed are estimated by NWS personnel by the amount and type of damage unless otherwise noted with an “M” which represents an actual wind speed as measured by official NWS approved anemometer.

When listing hail size under “Character of Storm”, ex. Hail (2.25), the hail size is given in inches and hundredths of inches.

When listing property and crop damage, the figures indicated are the best guess made by the NWS from the available sources of information at the time of the printing.

The fatalities, injuries, and damage amounts appearing in tropical cyclone events are attributed only to wind damage experienced in the coastal counties/parishes listed. Other tropical cyclone related events such as tornadoes and flooding are listed within their separate event types.
