Ida was a tropical storm with winds near 45 mph when it came ashore near Mobile Bay in southern Alabama on Tuesday morning.

The National Weather Service has issued a flash flood warning for north and central Georgia. Forecaster Kent McMullen said Tuesday that residents should expect from 3 to 5 inches of rain on Tuesday. He said some spots could be doused with up to 8 inches.
