Dozens of Tornadoes in 6 Southern States

Dozens of tornadoes spawned by a powerful storm system wiped out entire towns across a wide swath of the South, killing at least 200 people in the deadliest outbreak in nearly 40 years, and officials said Thursday they expected the death toll to rise.

Alabama's state emergency management agency said it had confirmed 131 deaths, while there were 32 in Mississippi, 15 in Tennessee, 13 in Georgia, eight in Virginia and one in Kentucky.

The National Weather Service's Storm Prediction Center in Norman, Okla., said it received 137 tornado reports around the regions into Wednesday night.

Dave Imy, a meteorologist with the prediction service, said the number of deaths was the most in a tornado outbreak since 1974, when 315 people died

One of the hardest-hit areas was Tuscaloosa, a city of more than 83,000 and home to the University of Alabama. The city's police and other emergency services were devastated, the mayor said, and at least 15 people were killed.

President Barack Obama said he had spoken with Bentley and approved his request for emergency federal assistance.

"Our hearts go out to all those who have been affected by this devastation, and we commend the heroic efforts of those who have been working tirelessly to respond to this disaster," Obama said in a statement.

The storms came on the heels of another system that killed 10 people in Arkansas and one in Mississippi earlier this week. (R)
