Tropical Storm Imelda formed Sunday, joining the monster Hurricane Humberto in the Atlantic, and forecasters warned it'll likely bring heavy rains to the Carolinas.
The big picture: Imelda is expected to strengthen over the Bahamas on Monday and become a major hurricane that night or early Tuesday. Forecasters expect the U.S. East Coast to be spared the worst of it — though there's a chance of heavy rainfall in the Southeast, and the Carolinas could see several inches of rain that may trigger flooding.
