New Jersey is in midst of an all-day nor’easter storm Tuesday with widespread concerns of flooding from up to 6 inches of rain possible by the time the powerful storm moves away from our area early Wednesday.
Some parts of New Jersey have already received more than 3 inches of rain before 7 a.m. as a flash flood watch continues until 8 p.m. for the entire state. Some flood warnings, which indicate imminent threats, are also in effect this morning.
“The exact location and movement of a slow moving band of heavy rain with embedded thunderstorms through this afternoon will determine whether and where a swath of 5 to 6 inches of rainfall falls,” the National Weather Service’s New York office said. That office, which, covers Bergen, Essex, Hudson, Union and Passaic counties, says the heaviest and steadiest rain should fall through about 4 p.m.
In addition to the widespread 1.5 inches of rain that has already fallen, the northern half of the state is likely to receive an additional 1 to 2 inches of rain starting at 8 a.m., the National Weather Service’s Mount Holly office said in an updated briefing issued Tuesday morning.
A pocket of Sussex and Morris counties could see 2 to 3 more inches of rain.
Coastal areas of Middlesex and Monmouth counties as well as areas north of Interstate 78 are at the greatest risk of flash flooding. There’s also a chance of wind gusts as high as 25 to 35 mph along the Jersey Shore this evening.
While rain isn’t expected to taper off until Wednesday morning, the intensity of the rain is likely to ease this afternoon, the weather service said in its morning forecast discussion. Some dry stretches will move into South Jersey by this evening.
Minor flooding is taking place at the Ho-Ho-us Brook in Ho-Ho-Kus, the weather service says. Several other waterways, including the Neshanic River, the Rockaway River and Green Brook are near flood stage before 7 a.m.
Multiple local road closures have been reported, though power outages have not been a major problem with about 2,500 homes and business without electricity early Tuesday. That could increase, however, as winds build through the day.
Wednesday high tides could also bring minor flooding to the Jersey Shore and along the Delaware Bay. Spotty minor flooding is expected on Tuesday.
Highs will be in the low 60s during the day before dropping into the 50s overnight.
Flash flood watch
A flash flood watch remains in effect across most of northern and central New Jersey until 5 p.m. Tuesday and in Bergen, Essex, Hudson, Passaic and Union counties until 6 p.m. Tuesday.
At about 9:30 a.m., the National Weather Service canceled the flash flood watch that had been in effect in Atlantic, Camden, Cape May, Cumberland, Gloucester and Salem counties in South Jersey, along with Berks, Chester, Delaware, Montgomery and Philadelphia counties in eastern Pennsylvania.
