Coastal Flood Advisory Affects Philadelphia Area Through Sunday Morning
Up to one foot of flooding expected in low-lying coastal areas from early Sunday morning through 6 AM, potentially closing vulnerable roads.
PHILADELPHIA, PENNSYLVANIA — The National Weather Service has issued a coastal flood advisory for Philadelphia and surrounding counties, effective through 6:00 AM EDT on Sunday. Residents are warned of potential inundation in low-lying areas near shorelines and tidal waterways.
The advisory, initially issued at 3:00 PM EDT on Friday and updated at 1:37 AM EDT on Saturday, warns of up to one foot of water above ground level in vulnerable coastal areas. The flooding window extends from 1:00 AM to 6:00 AM EDT on Sunday morning.
Affected Areas
In Pennsylvania, the advisory covers Delaware County, Philadelphia, Eastern Montgomery County, and Lower Bucks County. Across the Delaware River in New Jersey, Gloucester, Camden, and Northwestern Burlington counties are also under the same warning.
The National Weather Service Mount Holly office, which issued both advisories, warns that flooding will begin on the most vulnerable roads along tidal waterways during this timeframe.
Expected Impacts
Weather officials indicate that some partial or full road closures are possible as water levels rise in coastal and tidal areas. The advisory specifically targets low-lying regions that typically experience flooding during high tide events.
Residents in affected areas should monitor local conditions and avoid driving through flooded roadways. The advisory remains active until Sunday morning when water levels are expected to recede.
Safety Recommendations
The National Weather Service advises motorists to never drive through flooded roads, as even shallow water can be dangerous for vehicles. Officials recommend finding alternate routes if coastal roads become impassable during the overnight hours.
The coastal flood advisory represents a relatively minor flooding event compared to more severe coastal flood warnings, but still poses risks to transportation and property in the most vulnerable shoreline communities throughout the Philadelphia metropolitan area.
