The threat of flash flooding returned to North Carolina on Thursday, only days after Tropical Depression Chantal dumped heavy rain across the central part of the state, flooding homes and highways and leading to dozens of rescues.

A "considerable" flash flood warning has been issued in Boston as heavy, life-threatening rain pounds the city and areas to the south. Two to 4 inches of rain has fallen so far. Rainfall rates are reaching up to 2 inches per hour.
