Heavy rains and hail cause havoc in NJ on Sunday
More of New Jersey will be soaked by rain again on Monday.
A Flash Flood Watch has been issued for much of the state starting at noon in anticipation of more heavy rain for Hunderdon, Somerset, Middlesex and Monmouth counties as well as counties unaffected by Sunday's storms inclluding Mercer,Burlington Camden, Gloucester and Salem counties. Rain could fall as fast as 2-inches per hour creating flood conditions quickly and could include low visibility, gusty winds, hail, and frequent lightning.
Moderate-to-heavy rain was already falling in coastal Ocean County and in Gloucester County.
A cold front that brought Sunday's rain has moved further to the south on Monday meaning more of the state will get rain. "The chance for heavy rain and flooding will continue for both tomorrow and Tuesday," says Townsquare Meteorologist Dan Zarrow. "It looks like the area of heaviest rain will shift southward a bit, affecting mostly central and southern New Jersey.
The area south of Interstate 195 was been dry all day Sunday with only a few widely scattered showers. Coastal Monmouth County got a soaking on Sunday afternoon.
Sunday's storms produced hail anywhere from pea size in Warren County to nickel-and-quarter size in Sayreville and Laurence Harbor according to the National Weather Service, which reports several roads flooded out in Middlesex County. Roads were reported to be flooded in Old Bridge but other sections of town got barely a drop.
4.50 inches of rain fell in South Amboy in 90 minutes according to one NWS observer. Zarrow says in just 1 day, Newark Airport went from a 3" deficit for May to ABOVE normal precipitation.
Zarrow says these storms formed thanks to the combination of heat, humidity, and an approaching cold front. "There was a lot of atmospheric moisture to work with today, and that's why the very heavy rain was widespread across North Jersey," said Zarrow.
The rain did not make for a good ride for those heading north on the Garden State Parkway. Earlier heavy rain caused lanes to be flooded out on the Garden State Parkway in Union near Route 22, Routes 1 and 9 in Rahway and Interstate 280 in Newark. The Weather Channel reported casts stuck in high water on Route 22 in North Plainfield.
Flooding continued early Monday with sections of Routes 22 and 27 closed in Newark. The off-ramp from I-280 eastbound at #14 for Martin Luther King Boulevard remained closed while flooding blocked 2 lanes of I-287 in Hanover at Route 10.
