Coastal Flooding Advisories For Southeast PA Tuesday: NWS

PENNSYLVANIA - Gloomy skies and a wet forecast continue Tuesday as unseasonably cool temperatures and coastal flooding threaten Pennsylvania.

Several rounds of rain are set to pour down another 1 to 2 inches of rain on the region following a rainy weekend and Monday. Tuesday's embedded thunderstorms could bring heavier downpours, according to the National Weather Service, resulting in potential flooding, especially in localized urban and poor drainage areas.

Temperatures are also set to reach the mid-50s, with some locations poised to challenge record lowest high temperatures for Oct. 4, the National Weather Service said. Wind gusts could also reach up to 30 mph, with gusts up to 40 mph near the coast.

As of Tuesday morning, three Pennsylvania counties (Delaware, Philadelphia and Bucks) are under a coastal flood advisory, bringing up to one foot of flooding to some vulnerable areas through 9 p.m.

“Flooding of lots, parks, and roads with only isolated road closures possible,” the National Weather Service said in a statement. “If travel is required, allow extra time as some roads may be closed. Do not drive around barricades or through water of unknown depth. Take the necessary actions to protect flood-prone property.”

The good news: the rainy forecast is set to dissipate by late Wednesday after possible rounds of thunderstorms and rain. Cool temperatures in the high 50s are also set to arrive this weekend, per Accuweather.
