The U.S. suffered its second billion-dollar weather disaster of 2012 on April 3, when a massive hailstorm and 21 tornadoes hit the Dallas/Fort Worth, Texas region, said insurance company Aon Benfield, in their latest monthly Global Catastrophe Recap Report. They put the damage at $1 billion. The tornado outbreak included one EF-3 twister, which hit Forney, Texas. A severe hailstorm during the outbreak hit the DFW airport, damaging over 100 airplanes, and forcing the temporary closure of the airport. The other billion-dollar weather disaster of 2012 was the March 2 - 3 tornado outbreak in the Midwest and Southeast. NOAA put the total cost of the tornadoes that killed 41 people in Kentucky, Indiana, Ohio, and Alabama during the outbreak at $1.5 billion. There were two EF-4 tornadoes, one which devastated Henryville, Indiana, and another that plowed through Crittenden, Kentucky. On average, the U.S. sees 3 - 4 billion-dollar weather disasters each year, with 1 - 2 of these being severe weather/tornado outbreaks. In 2011, we already had five billion-dollar weather-related disasters by the first week of May, so we are well 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 came close, causing an additional $920 million in damage in Australia.

Canada and Midwest U.S. frost/freeze damage in the hundreds of millions of dollars
Damage to fruit trees in Ontario, Canada due to a series of frosts and freezes over the past six weeks will easily top $100 million dollars, said the Windsor Star this week. About 80% of the Ontario apple crop was wiped out. At the Ann Arbor Farmer's Market yesterday, I talked to a local apple grower who told me that her orchard in Southeast Lower Michigan had suffered at least a 90% loss of its apple crop. She said the story was similar for all the growers of apples, pears, peaches, nectarines, grapes, cherries, and plums in Michigan. "The only year that can compare was 1945," she told me, "and that year wasn't nearly as bad as 2012." Fruit crops in Pennsylvania and New York State have suffered heavy damage as well, and the total damage to agriculture from this year's freezes will likely be in the hundreds of millions of dollars. All of this damage occurred despite the fact that April temperatures across the region were above average. The culprit was the extraordinary "Summer in March" weather in mid-March 2012, which brought a week of 80°F-plus temperature to the region that triggered a record early bloom.

Hurricane season is coming
It's now mid-May, which means that hurricane season is about to start in the East Pacific. The official start of the East Pacific hurricane season is May 15, and the action is already starting to heat up. The first "Invest" of 2012 in the East Pacific, Invest 90E, is located about 700 miles south of Puerto Vallarta, Mexico, and is moving westward out to sea, posing no threat to any land areas. The European Center model predicts the possibility of another system getting organized in the East Pacific, closer to the coast of Mexico, during the period Wednesday - Friday (May 16 - 18.)
In the Atlantic, where hurricane season officially starts on June 1, the action may also be about to heat up. For the past several days, the GFS model has been consistently predicting the development of a subtropical storm in the Western Caribbean, or waters near Florida, sometime May 19 - May 21. The European Center model has not been on board with this, but has been predicting a very moist flow of tropical air will develop, bringing heavy rains to Florida May 19 - 20. So, it is possible we will see the Atlantic's first named storm occur in May this year, but the models are very unreliable this far out.
Have a great weekend, everyone!
