PHILADELPHIA - The strong nor’easter weekend weather continues to impact the Philadelphia region and nearby coastal areas Monday, bringing another round of tidal flooding, rough surf and lingering gusty winds. 

While rainfall has tapered off inland, coastal New Jersey and Delaware communities are facing ongoing flooding and beach erosion as water levels remain elevated into the afternoon, according to Monday's briefing by the National Weather Service, Mount Holly.

Wind and Marine Conditions

Winds are gradually diminishing, but gusts between 40 and 50 mph continue this morning along the coast, with inland areas around Philadelphia and Wilmington seeing 30 mph gusts at times.

The High Wind Warning for Monmouth and Ocean Counties remains in effect until noon, while a Wind Advisory covers inland and Burlington County through midday.

Out at sea, waves remain between 12 and 18 feet, creating dangerous conditions for boaters and prompting ongoing Gale Warnings. The NWS warns of substantial beach erosion and dune breaches in several coastal communities.

Rainfall Totals

Most of the heavy rain has moved offshore, but Monmouth and Ocean Counties could see an additional 1–2 inches of rain through Monday night, while inland locations around Philadelphia and South Jersey will see less than half an inch.

Nor'easter Outlook

Conditions are expected to gradually improve Monday night into Tuesday, though lingering coastal flooding is possible through the next high tide cycle. Forecasters expect calmer weather and cooler temperatures midweek as the nor’easter pulls away from the coast.
