A major storm system is drenching the southeastern U.S., bringing heavy rain and severe weather from the Gulf Coast to Virginia.

The storm, which began on May 12, has triggered flood advisories and severe thunderstorm warnings, with some areas expecting up to 10 inches of rain.

Over 36 million people are at risk, with possible tornadoes, damaging winds, and hail.

Flooding has already impacted parts of North Carolina, and officials are monitoring the storm’s potential to worsen over the coming days.
