NJ Weather: Flood Warnings, Up To 2 More Inches Of Rain In Forecast

NEW JERSEY - A wet weekend is in store for New Jersey, with several inches of precipitation already triggering flood warnings and more rain on the way, forecasters said.

While over three inches of rain have already fallen in the last 24 hours in areas like Pemberton and Toms River, up to two more inches of rain are set to fall on the Garden State through Sunday night, the National Weather Service said.

The northeasternmost portion of the state is likely to see the most additional rainfall, while South Jersey and parts of the Jersey Shore could see between 1 and 1.5 inches through Sunday, the agency said. Less than an inch of rain is predicted in areas hugging the shore south of Toms River to Cape May, according to an updated rainfall map posted Saturday.

Good morning! Periods of rain continue today, heaviest and steadiest over our northern NJ counties. After a lull later today into tonight, more rain is expected Sunday and it could be heavy at times with the potential for some embedded thunderstorms. #NJWX #PAWX #MDWX #DEWX pic.twitter.com/vl59Q5TdKr

As of 2:30 p.m., there’s a flood warning in Monmouth and Ocean New Jersey counties through 4 p.m. Saturday.

“Flooding of rivers, creeks, streams, and other low-lying and flood-prone locations is imminent or occurring,” the National Weather Service said in the warning, adding that excessive water has impacted Barnegat Bay, Toms River, Long Branch, Asbury Park, Lakewood, Middletown, Howell, Marlboro, Barnegat, Tinton Falls, Holmdel, Red Bank and Beachwood.

Interstate 195 between mile markers 25 and 34 and the Garden State Parkway between mile markers 57 and 118 are also impacted, the agency said.

“Turn around,” forecasters added. “Don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Do not drive around barricades or drive through water of unknown depth.”

Salem County and inland Ocean County are also under a hazardous weather outlook, with minor coastal flooding possible Sunday.
