once-in-1,000-year rainfall event

A once-in-1,000-year rainfall event from an unnamed storm floods homes
and forces rescues in North Carolina

 Floodwater surged into homes, stranded vehicles and forced water
rescues in coastal North Carolina on Monday after a tropical
storm-like system dumped historic amounts of rain in a matter of
hours.

"It's probably the worst flooding that any of us have seen in Carolina
Beach," Town Manager Bruce Oakley told CNN of the tourist town not far
from Wilmington. "We've had to rescue people from cars, also some from
houses and businesses."
