An area of the storm that dropped more than an inch of rain on New York City in an hour this afternoon was moving northeast, according to the weather service. The speed with which the area of rainfall was moving should mean no single town should be effected by the heavy rain for long, the weather service noted in the flood advisory.
Ponding on roadways and flooding of streams and rivers is possible.
Scattered showers and thunderstorms are expected to continue Saturday, which may include heavy downpours and result in flooding.
