Wildfire Risk Increases With Record Drought Conditions

The worsening drought across the United States is the subject of numerous news reports. A couple of stories caught our eye:

CNN reports that as of last Tuesday, some 61 percent of the contiguous U.S. was experiencing drought conditions – stretching from Nevada to South Carolina. Apparently, this
is the highest percentage in the 12-year record of the U.S. Drought Monitor.

The Lede blog at the New York Times posts that more than 1,000 counties in 26 states across the
country have been named natural disaster areas by the U.S. Department of Agriculture. It cites government officials saying this is the single largest designation in the program’s history and the worst drought since 1988.

Higher temperatures and drier conditions increase the risk of wildfire activity. In just the past three weeks, total acres scorched by wildfires jumped from 1.1 million to 3.1 million.

Over at Wunderblog, Dr. Jeff Masters posts that it has been another severe year for wildfires in the U.S., with the National Interagency Fire Center reporting 4800 square miles of burned acreage so far in 2012, an area about 87 percent the size of Connecticut:

This is pretty close to the 10-year average for this point in the year, and ranks as the fourth highest of the past ten years. However, with summer not yet half over, and more than 2/3 of the Western U.S. experiencing moderate to extreme drought, the Western U.S. fire season still have plenty of time to add significant acreage to its burn total.†

So far, Colorado has been hardest hit by this year’s wildfires. In its 2012 Half Year Natural Catastrophe Review Munich Re noted that two major wildfires in Colorado in June (the “High Park” fire near Fort Collins, and the “Waldo Canyon” fire near Colorado Springs) caused record damage in the state. Insured losses from both fires are estimated at US$ 500m, Munich Re said.
