Drought conditions

In Iraq, the worst sandstorm in living memory—according to reports—lasted for more than a week, beginning at the end of June and continuing into the first week of July. Hundreds of residents with respiratory complaints flooded local hospitals and numerous flights were delayed in Baghdad (Source: Reuters). Another large storm kicked up dust once again at the end of the month.

At the beginning of July, Britain continued to experience its warmest heat wave in three years, with a level three heat wave alert (their second highest alert level) issued for the first time since 2006. Britain's health service reported more than 300 calls for heat-related illnesses. The heat wave also affected Belgium, Germany, and France (Source: AP).

As of July 28th, moderate to severe drought persisted across much of California and Wisconsin, parts of Nevada, New Mexico, Oklahoma, and portions of the Hawaiian Islands. Overall, about 11 percent of the U.S., including Alaska, Hawaii, and Puerto Rico, experienced moderate to severe drought.

As severe drought conditions continued to plague Southern California, a brushfire broke out near the Getty Museum in Los Angeles on July 8th, burning 80 acres and causing evacuation of about 1,600 visitors and 800 employees from the world-famous art complex and 75 conference attendees from nearby Mount St. Mary's College. Ventilation systems were shut down to prevent smoke damage to the museum's priceless artwork. No damages were reported but the museum remained closed through July 9th as the fire was contained (Source: AP).

In South Central Texas, drought conditions continued to deteriorate through July, with most of the region experiencing exceptional drought, as defined by the U.S. Drought Monitor. Average temperatures were generally above-to-well above normal during this period, with many areas reaching the triple digits on consecutive days, including a record high temperature of 109°F (43°C) set at Poteet, Texas on July 6th. Conditions severely impacted crops and livestock production, as crops wilted and farmers were forced to cull their cattle. According to reports, over 60 percent of beef cows in the state are located in counties in extreme to exceptional drought (Source: AP). Experts at Texas A&M University estimate that agricultural economic losses could surpass the 4.1 billion dollar mark set during the last drought in 2006 (Source: UPI).

A heat wave in the U.S. Pacific Northwest during the last week in July led to numerous reports of record temperatures. High temperatures reportedly reached 92°F (33°C) in the typically cool region of Astoria, Oregon on July 28th, shattering the old daily record of 82°F (28°C). According to the National Weather Service, the high temperature at the Seattle-Tacoma International Airport on July 29th was 102°F (39°C)—the highest temperature ever recorded at that locale during the 118-year period of record. With abnormally dry to moderate drought conditions already in place, the remainder of the 2009 summer wildfire season is expected to be above normal, primarily due to lightning strikes, according to a U.S. Forest Service bioclimatologist (Source: msnbc.com)

As of July 31st, moderate drought was present in small sections of the provinces of Inner Mongolia, Hebei, Jilin, and Xinjiang (Source: Beijing Climate Center).

At least two homes were reported to be damaged from falling debris (Sources: AP, NY Daily News). The violent storms moved northeastward through much of Massachusetts. In Hopkinton, a super-cell—the most powerful form of thunderstorm—with golf-ball sized hail and 80 mph (129 km/h) winds, ripped off tree limbs and blew debris through the air.
