Some parts of New Jersey have been saturated with as much as 6 to 7 inches of rain, and more is on the way.
For anyone who was hoping the washed-out weekend marked the end of the soggy misery across New Jersey, there's some bad news: More rain is on the way. And, just like the rain that fell the past two days, it could be heavy at times.
That's what the National Weather Service is predicting, as a pesky mass of warm and humid air that has been stuck over the Garden State since Saturday is taking its time to move away.
"There's a frontal boundary that's kind of stalled out and meandering around the area," said Lee Robertson, a meteorologist at the National Weather Service's regional forecast office in Mount Holly.
As a result, rain showers and thunderstorms will continue to develop Sunday night, Monday morning and into Monday evening, Robertson said. Although there could be a break in the precipitation at times, it could quickly start up again and pick up in intensity.
State of emergency lifted in Princeton area
With the threat of heavy downpours adding to the 4 to 6 inches of rain that has already fallen over parts of Central New Jersey, flash flooding can develop and make driving dangerous on saturated roads, the weather service said. A flash flood watch is in effect for seven counties through 11 p.m. Monday: Hunterdon, Mercer, Middlesex, Morris, Somerset, Sussex and Warren.
Even though the alert doesn't include other counties at this time, Robertson noted heavy downpours can develop over any part of New Jersey now through Monday night. One area not in the flash flood watch zone is central Ocean County, where 5 to 6 inches of rain fell during a few hours on Sunday morning.
Update: At about 9 p.m., a heavy band of rain was moving through northeastern sections of New Jersey, prompting the weather service to issue a flash flood warning for Bergen, Passaic and Hudson counties, effective through 12:30 a.m. Monday. The warning also includes New York City, and the weather service reported several water rescues on flooded roads in Wayne, where 2 to 4 inches of rain fell during a short span.
RAINFALL TOTALS ACROSS N.J.
Here's a look at the rainfall totals from Saturday and Sunday across the state, as reported by the National Weather Service, the Community Collaborative Rain, Hail and Snow Network, and the New Jersey Weather & Climate Network at Rutgers University. (Note: Every town in the state does not have a weather monitoring station, and some stations have not yet reported their updated rainfall totals for Sunday. So some of the totals below can actually be higher.)
