The storms that have recently ripped through the South included dozens of tornadoes. And as the bad weather barreled north today, the National Weather Service declared a tornado watch for eastern parts South Carolina, North Carolina, Virginia, and Maryland, and warned of severe weather as far north as Boston. Strong wind from any sort of severe weather can wreak havoc, but the speed and spinning winds of a tornado are especially destructive. In most years, tornadoes kill about 60 Americans, about the same number killed by lightning strikes. But this is not going to be an average year. The death toll from the terrible storms in the South is approaching 300 and the number is climbing. Advice from the Centers for Disease Control and Prevention and the National Weather Service’s Storm Prediction Center can help you survive a tornado if one is headed your way.
