More than 8 million people are facing the threat of powerful tornadoes as a severe weather event sweeps across the Southeast to the Ohio Valley. The storm system, which intensified on Monday and Tuesday, has already caused significant damage in several states.
On Monday, severe thunderstorms hit areas from Texas to Illinois, resulting in reports of tornadoes in Oklahoma and large hailstones. The Storm Prediction Center has issued warnings for potential long-track tornadoes, hail larger than 2 inches in diameter, and destructive winds up to 75 mph.
