Tropical Storm Chantal is expected to produce heavy rainfall across portions of the coastal plain of the Carolinas through Monday. Storm total rainfall of 2 to 4 inches, with local amounts up to 6 inches, is expected. This rainfall will result in an elevated risk for flash flooding.

Tropical Storm Chantal has developed off the coast of Florida, and is moving slowly north at just 2 mph, becoming the season's third named storm.

South Florida faces a muggy Saturday with mid- to upper-80s heat, scattered late-morning storms, and lingering haze from fireworks, while rain chances ease into next week.
