Another Round Of Heavy Rain In NJ Forecast: See Timing, Details

NEW JERSEY — Another round of heavy rain is in the forecast this week for New Jersey one week after the remnants of Hurricane Ida brought tornadoes and flooding to the region.

The National Weather Service warns that heavy rainfall could hit the Garden State on Wednesday, bringing with it severe thunderstorms, hail and dangerous cloud-to-ground lightning.

Wednesday's anticipated storm also brings the threat of damaging winds and isolated tornadoes, the National Weather Service said. The greatest tornado threat is near and north of Philadelphia.

According to the weather service, there is a 50 percent chance of showers and thunderstorms starting at 11 a.m. Wednesday. As of Tuesday afternoon, a flash flood watch has been issued for Bergen, Essex, Passaic, Hudson, Hunterdon, Mercer, Middlesex, Morris, Somerset, Sussex, Warren and Union counties.

While new rainfall amounts of less than a tenth of an inch are expected during the daytime, there could be higher amounts in areas that get thunderstorms.

"Given the very saturated soils from recent heavy rain events, additional brief heavy rainfall of one to two inches may quickly lead to flooding of flood prone and other low-lying areas due to rapid runoff," the National Weather Service said.

The chance of rain continues into Wednesday night, when some of the storms could produce heavy rainfall. The chance of precipitation increases to 80 percent Wednesday night. New rainfall amounts between a quarter and half of an inch are possible, according to forecasters.

On Tuesday, Hurricane Larry was churning the Atlantic Ocean with 115 mph winds several hundred miles southwest of Bermuda. Larry, a major category 3 hurricane, could cause “life-threatening surf and rip current conditions” along the Jersey Shore and other parts of the East Coast by the middle of this week, according to the National Hurricane Center.

The latest round of potentially heavy rain comes just a week after the remnants from Hurricane Ida pounded the region on Sept. 1, with flooding that devastated several towns and tornadoes that leveled at least 20 homes. More than 40 people in New Jersey, New York and Pennsylvania died in the wake of the storm. At least 27 of those who perished hailed from the Garden State, Gov. Phil Murphy confirmed on Monday.
