Dangerous circulation passing south of Samantha in northern Tuscaloosa County.

Tornado warning for northern Tuscaloosa County.

No significant damage yet. Trees were reported down on Union Grove Road in Tuscaloosa a few minutes ago.

This activity will affect the northern half of the Birmingham metro by 3:15 am. Unstable air is really lifting up I-59/20 right now toward Birmingham so these storms will have to be taken seriously.

There are intense gradient winds all over the area, even outside the thunderstorms. These gradient winds could bring down isolated trees.
