Strong winds and torrential rain were expected to pose a serious flood risk across the Southeast on Thursday, part of a severe storm system that spawned tornadoes in Oklahoma and Arkansas, injuring at least 10 people — one of them critically.
Flash-flood warnings were in effect for parts of Mississippi, Tennessee, Louisiana and Arkansas, the National Weather Service said, while flood watches were issued as far as northern Florida, Alabama and Georgia.
Tornado warnings were also in effect for parts of Louisiana and Arkansas as of 4:30 a.m. ET.
"There's severe risk in play from Nashville to Tallahassee," said Kait Parker, a meteorologist for The Weather Channel.
