A five county area southwest of Lubbock experienced hazardous blowing dust conditions that contributed to twelve chain-collision automobile accidents and destroyed vast cotton crops. An elderly man was killed in a multi-vehicle collision, numerous motorists were injured, and total property losses were estimated to exceed $2.1 million dollars. The dust storm was a classic example of the haboob phenomenon, commonly observed in the deserts of Africa, and less frequent in the arid regions of the southwestern U.S. The South Plains haboob was associated with outflow from a complex of severe thunderstorms, and was characterized by a visually dramatic and densely whirling wall of dust as it progressed southwestward up to seventy miles from its source region. Wind speeds that accompanied the dust storm were generally sustained in the 30 mph range, with a few gusts over 50 mph. Visibilities were reduced to near zero along U.S. Highway 62/82 as the dust storm enveloped a portion of that route from Lubbock to Brownfield between 15:00 and 16:00 CST. Twelve separate vehicle accidents were attributed to low visibilities in blowing dust over a ten mile stretch, and involved at least twenty-seven vehicles including motorcycles and several large trucks. A 71 year old gentleman was killed when his vehicle slammed into the back of a jack-knifed tractor-trailer at highway speeds. Another fifteen motorists were injured in the life-threatening travel conditions. The impacts of the west Texas South Plains dust storm was additionally felt in the region’s agricultural market. Local and state officials report at least 10,000 acres of cotton were “burned” during the event, equating to a loss of over $1.5 million. Experts say the wind-driven dust stripped leaves from the young cotton plants which were already struggling to emerge due to drought-related stress.

The result was nearly five days of showers and thunderstorms across the Washington/Baltimore Region. Due to the tropical nature of the airmass, exceptionally heavy rain occurred in short periods of time. The high rain rates combined with scattered thunderstorms, which in a few cases reformed over the same areas, producing exceptionally heavy rainfall. The entire region, from the Allegany Front and Potomac Highlands of the Appalachian Mountains, east to the Chesapeake Bay, had at least two inches of rainfall during this period. Five to ten inches was fairly common all across the Washington Metro Area. While Baltimore did not have quite as much rainfall as Washington, it was still excessive. Many of the Baltimore suburbs had more rain than either the Inner Harbor or Baltimore/Washington International Airport reporting stations. Eastern portions of the city had over 10 inches of rainfall during the period June 23 through June 27. However, many places that experienced reforming and training thunderstorms had over ten inches of rainfall. The Delmarva had enhanced thunderstorm-induced rainfall conditions on June 24 and June 25th. Places like Federalsburg, Maryland had to be evacuated when over ten inches fell in only 24 hours. Washington DC and Columbia, Maryland had similar conditions on June 25th, when seven to ten inches of rain fell in only 24 hours. Northeast Maryland, just east and northeast of Baltimore, experienced extreme rainfall on June 25th, when seven to ten inches of rain fell in only 24 hours. One of the highest rainfall totals in the entire region was at North Bel Air, MD, just north of Baltimore, which had nearly 12 inches. Another maximum rainfall area was just west of Baltimore in the Laurel and Mount Airy areas, with around 10 inches. Washington DC had several federal buildings closed, a mudslide occurred over the Capital Beltway, dozens of roads were closed, and cars were swept from parking garages and streets. Many swift water rescues were needed and dozens of buildings and homes were damaged and uninhabitable. Unfortunately, five people lost their lives to the ravages of flood waters during this flooding event. New Washington National Airport records: 24 hour rainfall record: 7.94 inches Record rainfall for one week: 11.20 inches Record rainfall for a 2 day period: 9.41 inches Daily rainfall record for Sunday, June 25: 5.19 inches Daily rainfall record for Monday, June 26: 4.22 inches First time more than four inches of rain fell on two consecutive days Record rainfall for June: 14.02 inches New Baltimore records at Baltimore/Washington International Airport: Daily rainfall record for Sunday, June 25: 2.75 inches Few of Baltimore’s official excessive precipitation records were exceeded by this event. These records were firmly set in August 1955, due to the remnants of Hurricanes Connie and Diane. 5 The photos are from Rock Creek Park in Washington, DC.

MYRICK NOAA/National Weather Service, Reno, Nevada JEREMY R. MICHAEL NOAA/National Weather Service, Elko, Nevada (Manuscript received 29 October 2013; review completed 8 January 2014) ABSTRACT A slow-moving complex of thunderstorms formed across northwestern Nevada on 10 June 2013 in the deformation zone of an approaching upper-level low-pressure system. Storm redevelopment along outflow boundaries resulted in urban and rural flash flooding. On the eastern flank of the thunderstorm complex, strong outflow boundaries lofted dust to form a large haboob. The haboob propagated eastward across north- central Nevada and resulted in a 27-car pileup on Interstate 80 near Winnemucca. Three examples are presented that demonstrate how dual-polarization radar technology aided forecasters in (i) discriminating heavy rain from hail and (ii) tracking the haboob. 1.

These native elk were extirpated just prior to 1900. In February 1913, private conservationists released 83 elk from Yellowstone National Park into Cabin Draw near Chevelon Creek. Two other transplants of Yellowstone elk followed in the 1920s—one south of Alpine and another north of Williams. As a result of these original transplants, Arizona’s elk population has grown to levels that support annual harvests of 8,000 or more elk. Regulated hunting of the transplanted Yellowstone elk began in 1935 and continues today, with only a brief hiatus during 1944 and 1945 due to World War II. During the late 1940s and early 1950s, concerns over growing elk herds lead managers to increase permits, culminating in 1953 when 6,288 permits were issued and 1,558 elk were taken, more than 1,000 of which were cows. Elk permits leveled off and remained below 5,000 through the mid-1960s, when they were again increased in response to expanding populations.

    Sand and Dust Storms: Acute Exposure and Threats to Respiratory Health

    American Thoracic Society PATIENT EDUCATION | RAPID RESPONSE SERIES Sand and Dust Storms: Acute Exposure and Threats to Respiratory Health Sand and dust storms are lower atmosphere events that occur when strong winds pass over dry loose sand or soil. Sand and dust storms, also known as a haboob (Arabic for strong wind) are caused by airborne organic and inorganic debris, ranging from large sand particles to small dust particles, lifted from the surface of the land. This phenomenon excludes other sources of dust such as indoor environmental dust, cosmic dust, volcanic dust and smoke particles. Sand and dust storms can cause respiratory problems for people who are exposed, particularly those who have lung disease. As an example, in early July 2018, Arizona experienced strong winds resulting in the first big dust storm of the 2018 monsoon season. Dust storm.
