Philadelphia, Pennsylvania — Heavy rain will move into the Philadelphia region Wednesday afternoon, intensifying during the evening commute with the highest impacts expected between 4 p.m. and 8 p.m. across Philadelphia, Camden, Wilmington, Chester, and Norristown.
According to the National Weather Service, showers will develop after 2 p.m. Wednesday and become widespread by late afternoon, with rainfall totals reaching up to 1.00 inch by early Thursday. The heaviest rain is expected from 4 p.m. to 8 p.m. across southeastern Pennsylvania and nearby New Jersey.
Rainfall at this rate will quickly create slick roads and pooling water on major routes including I-95, I-76, and the Schuylkill Expressway. Low-lying underpasses in Center City and flood-prone intersections in Camden and Chester may take on water within minutes, reducing visibility and slowing traffic.
This is part of a broader system moving through the Mid-Atlantic, driven by deep moisture and a passing disturbance that enhances steady rainfall.
Drivers should avoid water-covered roads and expect delays during the 4 p.m. to 8 p.m. peak window. Allow extra travel time and use caution on highways where visibility may drop अचानक during heavier bursts of rain.
