Hazardous Weather Outlook In N.J., More Flooding Expected [VIDEOS]

Just a day after as much as six inches of rain fell on New Jersey, more downpours, thunderstorms and flooding are expected to hit the state, according to the National Weather Service.

A hazardous weather outlook was issued for the entire state, saying scattered, slow-moving torrential downpours can lead to localized flooding, especially on Monday afternoon and evening.

A flash flood watch is in effect until 11 p.m. for portions of New Jersey and Pennsylvania, including eastern Monmouth, Hunterdon, Mercer, Warren, Middlesex, Morris, Somerset and Sussex counties in New Jersey and Berks, Carbon, eastern Montgomery, Lehigh, lower Bucks, Monroe and Northampton counties in Pennsylvania.

Additional showers and thunderstorms are likely through Monday evening across the flood watch area. Rainfall from these showers and thunderstorms could lead to more flash flooding, especially in areas that have already received heavy rainfall, according to the NWS.

The potential exists through Monday evening for some locations to see one to two inches of new rainfall in less than an hour, according to the NWS.

Showers and thunderstorms over the weekend produced very heavy rain and serious flooding across the region, with four to six inches of rain falling in some locations.

The Flemington-Raritan First Aid and Rescue Squad reported severe flash flooding in the southern portion of Hunterdon County, especially in a swath through Flemington, Raritan Township and Readington Township.

"While not the worst flooding in the area's history, the storm caused an extremely rapid flooding condition," according to the squad's Facebook post.

In once instance, the squad reported that a man was trapped in a vehicle in rapidly rising water, while another driver was unable to safely escape the flooded area. The squad's crews entered the water, pulled alongside the driver and helped the driver into the rear cargo area. The driver then drove out of the flooded area to safety.
