There were three potential storm-related deaths in North Carolina amid flooding from the remnants of Tropical Storm Chantal, a state official said Tuesday.

Tropical Storm Chantal has been downgraded to a tropical depression but is raising concerns of flash flooding in central North Carolina and south-central Virginia.

Tropical Storm Chantal might have had the perfect recipe for catching people unawares: It formed rapidly (only reaching tropical storm status on Saturday) over a holiday weekend and moved slowly while dropping torrential rain.
