N.J. weather: Flash flood watch expands to 17 counties. Nor’easter could dump up to 4 inches of rain.
A flash flood watch for New Jersey has been extended to 17 counties as the state braces for a nor’easter storm with severe thunderstorms and damaging winds that could deliver up to 4 inches of rain between Monday night and Tuesday afternoon.
The nearly statewide flash flood watch (all counties except Camden, Cumberland, Gloucester and Salem) runs from 8 p.m. Monday until 5 p.m. Tuesday, the National Weather Service said. It’s still expected to rain in the South Jersey counties not under the watch, though.
About 2.5 to 3.5 inches of rain is expected in a large chunk of the state, which could lead to flash flooding of creeks, streams, urban areas and areas with poor drainage.

Monday should be mainly dry with most of the rain falling from late Monday night through much of the day Tuesday, the weather service said in its morning forecast discussion. Some showers could move in late this afternoon, though.
Severe thunderstorms are possible Monday night with damaging winds that could pull down trees and power lines, leading to outages. The heaviest wind gusts — up to 45 mph — are likely Tuesday night along the Jersey Shore.
A nor’easter storm is expected to slam New Jersey with severe thunderstorms, high wind and heavy rain with accumulations up to 4 inches Monday night and into Tuesday.
Forecasters caution that a slight shift in the track of the storm could significantly impact rain totals. If the low moves closer to the Shore, it might mean more rain, while if the system slides further from the coast, impacts would likely be lesser.
Minor coastal flooding is expected along the Jersey Shore and the Delaware Bay from Tuesday morning through Thursday morning. Just spotty minor flood is likely along the Delaware River from Trenton south.
Meanwhile, most of Monday will be cloudy and mild as highs climb into the low 70s to mid 70s — 10 to 15 degrees above normal for later October. Lows will be in the 50s tonight before temps reach the low 60s Tuesday when the bulk of the rain falls. We’ll dry out Wednesday, though it will be cloudy. The sun is expected to return Thursday with highs in the low 60s.
