Damage estimates from superstorm Sandy have grabbed headlines, but the most expensive US weather disaster in 2012 may turn out to be the drought that has gripped half or more of the continental United States since late June.
As of early December, slightly more than 62 percent of the US remained in the grips of moderate-to-exceptional drought, with about 6.5 percent under exceptional drought – largely up and down the central Plains, but with small patches appearing at the southern tip of Texas, as well as in parts of Alabama and Georgia.
Rough estimates of the drought's economic impact range from $60 billion to more than $100 billion, according to Steve Cain, a disaster communication specialist with Purdue University's College of Agriculture in West Lafayette, Ind. The dry conditions not only are expected to lead to higher food prices, but have also contributed to wildfires that have blackened more than 9.1 million acres this year – the third-largest annual extent on record, after 2006 and 2007.
