Hundreds rescued as deadly Tropical Depression Sally sweeps Gulf Coast

"Catastrophic" flooding from Tropical Depression Sally spilled inland across eastern Alabama and southwestern Georgia on Wednesday, bringing peak winds down to 45 mph winds, per the National Hurricane Center.

Why it matters: The mayor of Orange Beach, Ala., said one person died in the storm and hundreds of others have been rescued, per AP. Sally made landfall as a Category 2 hurricane near Gulf Shores, before later being downgraded to a tropical storm and later a depression. But the NHC warned late Wednesday it's "still causing torrential rains over eastern Alabama and western Georgia."
