Flooding: Several rivers may experience moderate to major flooding, especially across northern NJ and southeast PA. River flooding risk continues Wednesday and beyond. Widespread urban & small-stream flooding is possible. Snowmelt and heavy rain across the northern areas will enhance runoff.
Strong/Damaging Winds: High Wind Watch for the NJ and DE coastal counties for the potential for southeast to south wind gusts up to 65 mph Tuesday night. There is lower confidence regarding how strong the winds get farther inland. A line of heavier showers Tuesday night with the cold front could potentially produce a period of stronger winds. Gusty west-to-southwest winds continue on Wednesday.
Marine: Storm Watch is in effect for all marine zones with gusts up to 55 knots possible. Dangerous seas building to 15-20 feet later Tuesday and lingering into Wednesday.
Coastal Flooding: Tuesday PM into Wednesday. Coastal Flood Watch for the potential for moderate flooding for the tidal Delaware River, Upper Delaware Bay, and eastern MD Shore areas. The severity of flooding will depend on surge timing with respect to high tide, and excessive runoff from heavy rain may elevate water levels even more.
Flooding Rains across the entire area, with the heaviest occurring Tuesday afternoon into Tuesday night. Widespread urban & small stream flooding, widespread moderate/major river flooding especially for northern New Jersey. Flooding continuing Wednesday and beyond.
