Philadelphia, PA – Damaging wind gusts and flash flooding are possible across Pennsylvania, New Jersey, Delaware, and northeast Maryland this afternoon as severe thunderstorms roll through between 2 and 8 p.m. Sunday.
According to the National Weather Service in Mount Holly, scattered storms are expected to develop early in the afternoon, with the strongest cells capable of producing wind gusts up to 60 mph and rainfall rates that could quickly overwhelm drainage systems. A Level 1–2 risk for severe weather and excessive rainfall covers much of the region, including Philadelphia, Trenton, Wilmington, and Allentown.
Localized flash flooding may impact low-lying roads, urban areas with poor drainage, and small creeks. Residents in flood-prone zones—especially near the Delaware River corridor—should remain alert and avoid travel during heavy downpours. Power outages are also possible due to falling limbs or downed wires from strong gusts.
In New Jersey, communities from Atlantic City to Newton could see rapidly changing conditions. Maryland’s Eastern Shore and parts of northern Delaware are also under threat.
The storms are expected to weaken after sunset. Additional alerts or warnings may be issued later today—stay tuned to local media and enable wireless emergency alerts on your device.
