Beyond New Jersey, flash flood warnings were also issued for Brooklyn, Queens, and Nassau County in New York, while Philadelphia and Camden County faced similar warnings due to reported flooded roads and numerous closures. Officials characterized the flooding in these areas as "life-threatening," with 2 to 3 inches of rain already recorded and the potential for more rainfall.

Forecasters predict that additional heavy rain and thunderstorms will continue through Monday night, with total rainfall expected to reach 3 to 4 inches in many regions, and possibly higher amounts in localized areas. The ground, already saturated from previous storms, has heightened the risk of rapid flash flooding across the region.
