Weather Update: Flash Flood Watch Effective Until Tuesday Morning

Merely hours after being pounded with heavy rain, New Jersey residents could be in for another bout of showers and thunderstorms on Monday.

Flash flood watches and advisories have been issued for much of the state, including Madison. The National Weather Service issued a flash flood watch for Madison, effective at noon on Monday through 6 a.m. Tuesday.

Showers and thunderstorms are expected across the region on Monday and are expected to become more numerous this afternoon and this evening, according to the National Weather Service. Weather forecasters say some of the storms could produce excessive “short duration rainfall,” dumping as much as 2 inches of rain in an hour in some areas.

These amounts could cause dangerous roadway flooding and could be amplified by blocked storm drains.
