Deadly storms in the past two weeks have unleashed dozens of tornadoes in the United States, mainly in the South and Midwest, killing at least 63 people and damaging or destroying hundreds of people’s homes.
This year's early severe weather, especially in the Midwest, is part of a trend seen over the past few years, according to Bill Bunting, chief of forecast operations at the National Weather Service Storm Prediction Center in Norman, Oklahoma.
