Minnesota WeatherTalk Newsletter for Friday, January 7th, 2011 To: MPR Morning Edition Crew From: Mark Seeley, University of Minnesota Extension Dept of Soil, Water, and Climate Subject: Minnesota WeatherTalk Newsletter for Friday, January 7th, 2011 Headlines: -Cold continues -Overlooked feature of 2010 weather -Experimental Extreme Cold Warning -Weekly Weather Potpourri -MPR listener question -Almanac for January 7th -Past weather features -Feeding storms -Outlook Topic: Cold continues to start 2011 Following a colder than normal December, January is continuing the pattern as mean temperatures are averaging 5 to 9 degrees F colder than normal through the first week of the month. Minnesota has reported the coldest temperature in the 48 contiguous states four times so far this month, the coldest being -33 degrees F at Bigfork on the 3rd. In fact several places including Bemidji, International Falls, Bigfork, Babbit, and Cass Lake have recorded -30 degrees F or colder already this month. Temperatures are expected to continue colder than normal well into the third week of the month, with perhaps some moderation in temperature and a January thaw during the last ten days of the month. Topic: Overlooked feature of 2010 weather In my write-up and radio comments of last week about significant weather in 2010 several people mentioned that I overlooked the flash flood event in southern Minnesota over September 22-23, 2010 affecting at least 19 counties. One of the largest flash floods in history, this storm produced rainfall amounts greater than 10 inches in some places (11.06 inches near Winnebago) and near record flood crests on many Minnesota watersheds. Indeed several roads and highways were flooded and closed. You can read more about this weather event from 2010 at... http://climate.umn.edu/doc/journal/flash_floods/ff100924.htm Topic: Experimental Extreme Cold Warning Several regional National Weather Service Offices, including Minneapolis and Duluth are participating in the trial use of an Extreme Cold Warning. This warning is triggered by expected low temperatures of -20 to -25 degrees F or colder. In the absence of very cold temperatures coupled with any significant wind which would normally lead to wind chill advisories and warnings, this warning will be issued to the public based on actual air temperatures that fall to dangerous levels. Other NWS offices in North and South Dakota will be using this warning as well. Its usefulness will be evaluated after the winter season. Weekly Weather Potpourri: More heavy snow was falling in Scotland this week, closing schools in some areas. According to the United Kingdom Meteorological Office December of 2010 was the coldest in the country since comprehensive records began in 1910. The month was dominated by cold, near record-setting temperatures and snow. Only five months in history have been colder than December 2010 in the United Kingdom: January 1940, February 2947, January 1963, February 1963, and February 1986. You can read more about this at..... http://www.metoffice.gov.uk/news/releases/archive/2011/cold-dec For Australia, 2010 was the 3rd wettest year in history and the especially heavy doses of rainfall in November and December produced widespread flooding there, especially throughout Queensland. Many areas received 15-20 inches of rainfall in December alone. Several rivers were well above flood stage and with showers in the forecast for this week they were expected to stay that way well into the new year. Portions of northern India have been in the grip of a cold wave this week with several deaths from exposure reported. Temperatures in Delhi fell as low as 39 degrees F, coldest of the winter so far. In parts of Kashmir temperatures were as cold as -10 degrees F for two days. MPR Listener Question: How did the 2010 mean temperature and total precipitation rank relative to state history? Did some record their wettest year in history? Answer: According to the Minnesota State Climatology Office preliminary climate data for 2010 indicate that it was the 9th warmest year on a statewide basis, but the 2nd wettest (trailing only 1977). The statewide average precipitation for 2010 was 33.44 inches. Indeed some observers did report their wettest year in history. These included: Wabasha with 49.92 inches, Caledonia with 49.01 inches, La Crescent with 48.07 inches, Hutchinson 41.71 inches, Marshall 43.86 inches, Pipestone 39.02 inches, Winnebago 44.53 inches, Amboy 44.08 inches, and Mora 41.71 inches. You can read more about the 2010 climate summary at the Minnesota Climatology Working Group web site.... http://www.climate.umn.edu/doc/journal/warm_wet_2010.htm Almanac for January 7th: The average MSP high temperature for this date is 21 degrees F (plus or minus 13 degrees standard deviation), while the average low is 5 degrees F (plus or minus 15 degrees standard deviation). MSP Local Records for January 7th: MSP weather records for this date include: highest daily maximum temperature of 52 degrees F in 2003; lowest daily maximum temperature of -11 degrees F in 1887; lowest daily minimum temperature of -34 degrees F in 1887; highest daily minimum temperature of 34 degrees F in 1965; record precipitation of 0.30 inches in 1989; record snowfall of 3.6 inches in 1989. Average dew point for January 7th is 5 degrees F, with a maximum of 37 degrees F in 1965 and a minimum of -33 degrees F in 1976. All-time state records for January 7th: Scanning the state climatic data base: the all-time high for this date is 59 degrees F at New Ulm (Brown County) in 1933 and at Amboy (Blue Earth County) in 2003; the all-time low is -54 degrees F at International Falls (Koochiching County) in 1909. The all-time record precipitation amount for this date is 2.50 inches at Hutchinson (McLeod County) in 1999. The state record daily snowfall for this date is 36.0 inches at Wolf Ridge Environmental Learning Center near Finland (Lake County) in 1994. Past Weather Features: January 7, 1873 began as a mild day with temperatures near 32 degrees F. But a massive winter storm brought blizzard conditions to the state by late in the day. The blizzard raged for most of 3 days, dropping temperatures into the -20 F and bringing several inches of snowfall. Over 70 deaths were reported, many livestock were lost, and the railroads were paralyzed for days due to high drifts. On January 7, 1909 northern Minnesota residents were caught in the midst of an arctic cold wave. Over 20 communities reported temperatures of -30 degrees F or colder. At International Falls the temperature remained below zero F from midday on the 4th to midday on January 13, a period of 216 consecutive hours. During that time the thermometer read -50 degrees F or colder on three days and climbed no higher than - 29 degrees F on January 6. January 7-9, 1969 brought a blizzard to central and northern Minnesota communities. Even though snowfall amounts ranged from 5 to 10 inches, winds up to 50 mph piled huge drifts across roads and highways, causing many closures. Most schools were closed for at least two days. January 6-8, 1989 brought a blizzard to Red River Valley communities in Minnesota. Many observers reported over a foot of snowfall (17 to 18 inches at Detroit Lakes and Fergus Falls) driven by winds of 35 to 50 mph. Both Interstates 94 and 29 were closed for a period of time. The abundant snowfall that melt helped contribute to flooding on the Red River later that spring. Record-setting snowfall occurred over the north shore (Lake Superior) region of Minnesota on January 6-7, 1994. Duluth reported 24.5 inches and Two Harbors reported 18 inches of snowfall. At Wolf Ridge Environmental Learning Center near Finland snowfall of 45 inches was measured over the two days, an incredible 36 inches coming on the 7th. Snow depth there was 49 inches, meaning snowshoes were mandatory to walk around outside. They reported a record 59.6 inches of snowfall in January of 1994. Words of the Week: Feeding storms This terminology is not used in the USA but more in Scotland. It refers to a snow storm that simply adds to the snow already on the landscape. Thus after permanent snow cover is established early in the winter season, one could argue that all snow storms are "feeding storms", adding to the quantity of snow cover. Given the existing spring snow melt flood threat already present on many Minnesota watersheds, we hope that the rest of the winter brings fewer "feeding storms" to our state. Outlook: Cold and dry over the weekend, with increasing clouds late on Sunday and a chance for flurries. Chance of light snow for Monday and Tuesday and continued colder than normal conditions next week. Increasing chance for snow towards next weekend.

    Supporting Shine (School Hydrological Information Network) Increasing Children’S Awareness and Participation in Disaster Risk Reduction

    Project ENCORE Enhancing Community Resilience to Disasters Supporting SHINe (School Hydrological Information Network) Increasing children’s awareness and participation in disaster risk reduction On September 26, 2011, Typhoon Nesat (Pedring) hit close to 3,500 communities in the northern region of the Philippines. Typhoon Nalgae (Quiel) hit on October 1, taking the same route. About 4 million were affected by the typhoons, destroying agricultural lands, road and water systems, health centers and 914 schools. A total of 101 people died, including 42 children. Save the Children’s Project ENCORE (Enhancing Community Resilience to Disasters) builds on the Nesat/Nalgae emergency as well as other programs’ experience to increase the understanding of the hazards the province of Bulacan faces. Through an innovative urban disaster risk reduction approach, the project aims to facilitate the organizing of child-led groups to disseminate DRR/mitigation messages and implement DRR/mitigation activities supporting the province's SHINe (School Project ENCORE aims to: Hydrological Information Network) program.

Nesat affected thousands of families in the 17 cities and municipalities in Metro Manila, especially those living in low-lying and flood-prone areas. The situation was worsened with the Typhoon Nalgae which brought-in heavy rains and badly affected provinces in Northern and Central Luzon. The National Disaster Risk Reduction and Management Council (NDRRMC) reported that a total of 1,183,530 families or 5,534,410 persons have been affected in 3,252 villages in 349 municipalities, 41 cities in the 34 provinces of Regions I, II, III, IV-A, IV-B, and V, CAR, NCR and Region VI. The number of Typhoon Nesat affected population alone practically comprised three-fourths of the average number of disaster-affected population in a given year, which is at 7 million. The NDRRMC also reported that the national death toll from Typhoons Nesat and Nalgae climbed to 55 individuals with 63 others injured and 30 more others still missing. Destruction of property was placed at 7,540 totally damaged houses and 41,224 partially damaged houses.

    Pacific Study (Focusing on Fiji, Tonga and Vanuatu

    1 EXECUTIVE SUMMARY 1.1 Hazard exposure 1.1. Pacific island countries (PICs) are vulnerable to a broad range of natural disasters stemming from hydro-meteorological (such as cyclones, droughts, landslide and floods) and geo-physical hazards (volcanic eruptions, earthquakes and tsunamis). In any given year, it is likely that Fiji, Tonga and Vanuatu are either hit by, or recovering from, a major natural disaster. 1.2. The impact of natural disasters is estimated by the Pacific Catastrophe Risk Assessment and Financing Initiative as equivalent to an annualized loss of 6.6% of GDP in Vanuatu, and 4.3% in Tonga. For Fiji, the average asset losses due to tropical cyclones and floods are estimated at more than 5%. 1.3. In 2014, Tropical Cyclone (TC) Ian caused damage equivalent to 11% to Tonga's GDP. It was followed in 2018 by damage close to 38% of GDP from TC Gita. In 2015, category five TC Pam displaced 25% of Vanuatu's population and provoked damage estimated at 64% of GDP. In Fiji, Tropical Cyclone Winston affected 62% of the population and wrought damage amounting to 31% of GDP, only some three and a half years after the passage of Tropical Cyclone Evan. 1.4. Vanuatu and Tonga rank number one and two in global indices of natural disaster risk. Seismic hazard is an ever-present danger for both, together with secondary risks arising from tsunamis and landslides. Some 240 earthquakes, ranging in magnitude between 3.3 and 7.1 on the Richter Scale, struck Vanuatu and its surrounding region in the first ten months of 2018.

As of 10 August, four people were killed, some 8,000 people were left homeless, and 200 meters of railroads were washed away. More than 12,000 hectares of rice paddies were flooded in Kam Pot province alone. Floods Nov 1999 Continued torrential rains during October and early November caused flash floods and affected five southern provinces: Takeo, Kandal, Kampong Speu, Phnom Penh Municipality and Pursat. The report indicates that the floods affected 21,334 families and around 9,900 ha of rice field. IFRC's situation report dated 9 November stated that 3,561 houses are damaged/destroyed. So far, there has been no report of casualties. Flood Aug 2000 The second floods has caused serious damages on provinces in the North, the East and the South, especially in Takeo Province. Three provinces along Mekong River (Stung Treng, Kratie and Kompong Cham) and Municipality of Phnom Penh have declared the state of emergency. 121,000 families have been affected, more than 170 people were killed, and some $10 million in rice crops has been destroyed. Immediate needs include food, shelter, and the repair or replacement of homes, household items, and sanitation facilities as water levels in the Delta continue to fall.

    Hurricane & Tropical Storm

    5.8 HURRICANE & TROPICAL STORM SECTION 5.8 HURRICANE AND TROPICAL STORM 5.8.1 HAZARD DESCRIPTION A tropical cyclone is a rotating, organized system of clouds and thunderstorms that originates over tropical or sub-tropical waters and has a closed low-level circulation. Tropical depressions, tropical storms, and hurricanes are all considered tropical cyclones. These storms rotate counterclockwise in the northern hemisphere around the center and are accompanied by heavy rain and strong winds (NOAA, 2013). Almost all tropical storms and hurricanes in the Atlantic basin (which includes the Gulf of Mexico and Caribbean Sea) form between June 1 and November 30 (hurricane season). August and September are peak months for hurricane development. The average wind speeds for tropical storms and hurricanes are listed below: . A tropical depression has a maximum sustained wind speeds of 38 miles per hour (mph) or less . A tropical storm has maximum sustained wind speeds of 39 to 73 mph . A hurricane has maximum sustained wind speeds of 74 mph or higher. In the western North Pacific, hurricanes are called typhoons; similar storms in the Indian Ocean and South Pacific Ocean are called cyclones. A major hurricane has maximum sustained wind speeds of 111 mph or higher (NOAA, 2013). Over a two-year period, the United States coastline is struck by an average of three hurricanes, one of which is classified as a major hurricane. Hurricanes, tropical storms, and tropical depressions may pose a threat to life and property. These storms bring heavy rain, storm surge and flooding (NOAA, 2013). The cooler waters off the coast of New Jersey can serve to diminish the energy of storms that have traveled up the eastern seaboard.
