The National Weather Service has issued a Flash Flood Watch for much of Northwest Georgia.

It is in effect from midnight tonight through Thursday afternoon.

Rainfall will become heavy over North Georgia late tonight and Thursday with rain amounts of 2 to 3 inches possible, with isolated higher amounts expected.

Runoff from the rain could push rivers and creeks above flood state.

Also, temporary street flooding and road ponding are possible due to poor drainage and clogged storm drains.
