After a year of wild, expensive and dangerous weather in 2011, 2012's weather in the United States was only a bit calmer. 2011 had a record 14 disasters that caused at least a billion dollars in damage. The damage from 2012's 11 billion-dollar-plus disasters could end up costing even more than 2011, with expensive repairs needed after Hurricane Sandy, as well as severe losses from the Midwest drought.
"NOAA estimates that the nation experienced 11 such events, to include seven severe weather/tornado events, two tropical storm/hurricane events, and the yearlong drought and associated wildfires."
