The first billion-dollar weather disaster of 2012 for the U.S. was the March 2 – 3 tornado outbreak in the Midwest and Southeast, said global reinsurance company AON Benfield in their latest monthly Global Catastrophe Recap Report. The total cost of the tornadoes that killed 41 people in Kentucky, Indiana, Ohio, and Alabama was $2 billion. The outbreak spawned two EF-4 tornadoes, one which devastated Henryville, Indiana, and another that plowed through Crittenden, Kentucky. The two other tornado outbreaks of note that occurred in February and March had damages less than $1 billion: the Leap Day tornadoes in Illinois and surrounding states ($475 million), and the Dexter, Michigan tornado EF-3 tornado of March 15 ($275 million.) I expect that the tornadoes that swept through the Dallas, Texas region last week will likely have a damage tally in the hundreds of millions, but fall short of the billion-dollar mark. In 2011, we already had two billion-dollar weather-related disasters by the first week of April, so we are behind last year’s pace. NOAA’s National Climatic Data Center logged a record fourteen billion-dollar weather disasters in 2011. There has been just one other billion-dollar disaster in the world this year, according to AON Benfield–severe flooding in Australia’s New South Wales and Victoria states in late February and early March that caused $1.58 billion in damage. A separate flooding episode in late January and early February caused an additional $920 million in damage in Australia.

A week for severe severe weather across the Plains and Midwest
Expect severe weather and tornadoes every day this week across the Plains and Midwest U.S., says NOAA’s Storm Prediction Center (SPC). A warm, unstable airmass will collide with cold air funneling down from Canada most of the week, creating conditions ripe for severe thunderstorms and tornadoes all week. The main focus of severe weather today will be over Western Oklahoma and portions of the Texas Panhandle, where SPC has issued their second highest level of alert, a “Moderate Risk.”

Video 1. Wunderground tornado expert Dr. Rob Carver alerted me to this remarkable railroad surveillance video recently posted to YouTube that captures a train derailed by a Tornado January 7, 2008 in Harvard, IL. The tornado moved across the Chicago and Northwestern railroad where it blew 12 railroad freight cars off the track. The train was moving at the time the tornado hit it, so as the main engine stopped, the remaining cars on the track continued along it and slammed into the front part of the train. No one was injured, but 500 residents in the nearby unincorporated town of Lawrence were evacuated because of the potential for a hazardous materials situation.
