TRENTON, N.J. — New Jersey is under a flood watch through late tonight as a strong storm system moves in from the west, bringing the threat of flash flooding with rainfall totals potentially reaching five inches in some areas.
The National Weather Service issued the alert for large swaths of the Garden State, including Atlantic, Ocean, Monmouth, Morris, Sussex and Warren counties, as well as neighboring regions in Pennsylvania, Delaware and Maryland.
Beginning around 2 p.m., widespread thunderstorms are expected to develop and intensify throughout the evening. The combination of high humidity, warm temperatures near 89 degrees, and a passing cold front is setting the stage for heavy downpours and rapid runoff.
“A very warm and humid airmass will be in place ahead of an approaching cold front,” the Weather Service noted in its advisory. “Forecast rainfall amounts of 1 to 2 inches can generally be expected, with localized amounts of 3 to 5 inches possible.”
Officials warn of possible flooding in low-lying areas, creeks, and streams, especially where storm drains are blocked or overwhelmed. Rainfall rates may exceed 2 inches per hour, increasing the risk of flash flooding in urban zones.
Tonight’s forecast includes a 90% chance of rain with possible thunderstorms, a low around 65 degrees, and wind gusts up to 20 mph from the northeast.
Emergency services across affected counties are on alert as residents prepare for rapidly changing weather conditions.
Flash flooding may impact travel and pose hazards to vehicles and pedestrians in flood-prone areas.
