Alabama schools are looking at plans for Friday ahead of expected early morning storms.

All of the state is at risk of seeing strong storms, with the northern two-thirds of Alabama having the better probability of severe weather. Strong to severe storms are expected to approach Alabama from the west early Friday morning — as early as 4 a.m. — and track eastward through the day.

The Madison County Sheriff’s Office is cautioning drivers to be aware of flooding in low-lying areas as the National Weather Service in Huntsville says to expect “multiple rounds” of showers and storms through Friday.

Flood warnings are in place through mid-morning for much of north Alabama as the upper part of the state could see as much as 5 inches of rain over 24 hours.

Jim Stefkovich, a meteorologist with the Alabama Emergency Management Agency, said between 1-3 inches of rain fell overnight with an additional 1-2 inches expected through this afternoon. Some of today’s storms could produce damaging wind gusts, he said.

A flood watch will continue for the northern part of the state through Friday at 6 p.m. The majority of the state will be under a wind advisory from midnight to 9 p.m. Friday.
