Severe weather threatens millions across Southeast and Northeast.

Nearly 23 million people in the Southeast are at risk of severe thunderstorms, including destructive winds, damaging hail, and strong tornadoes, with the possibility of a derecho. The threat has been increased to a level 4 on NOAA's Storm Prediction Center's 5-point severe thunderstorm risk category scale. The severe storms are expected to come in multiple rounds through Wednesday night and could pack wind gusts of over 80 mph, hail larger than 3 inches in diameter, and even a couple of EF-2 or stronger tornadoes. Additional rounds of severe weather are likely this weekend.
