Damage from tornadoes was confirmed in Alabama, Louisiana and Florida on Sunday, but no injuries have been reported.
Today, flood watches have been issued for four states -- Georgia, South Carolina, North Carolina and Virginia.
The storm system stretches from Florida to Tennessee on Monday morning with the Mississippi Valley seeing heavy rain and a few thunderstorms.
Heavy rain and strong thunderstorms are possible over the Carolinas as the secondary coastal low tries to develop this afternoon over Georgia. Some of the storms could be strong to severe with damaging winds and a small chance for a tornado.
As the coastal low moves up the coast, heavy rain will spread into the mid-Atlantic. Severe weather is not expected in the Northeast.
By Wednesday, the coastal storm should spread rain into New York City, Boston and the rest of the Northeast. Some of the rain could be heavy, but major flooding is unlikely.
The heaviest rain will fall where flood watches have been issued in the Carolinas and southern mid-Atlantic, where 4 inches locally is possible.
