Tidal flooding is expected to impact parts of New Jersey, Delaware, and southeastern Pennsylvania, including the Philadelphia area, during Wednesday’s high tide cycles. Persistent northeast winds are pushing water inland, prompting the National Weather Service in Mount Holly to issue a Coastal Flood Advisory for several communities along the tidal Delaware River and nearby coastal zones.
Areas Under Advisory and Flood Concerns
The advisory affects several key locations, including:
Philadelphia and Wilmington along the Delaware River
Atlantic City, Cape May, and Long Branch in New Jersey
Lewes to Bethany Beach along Delaware’s coast
Minor flooding is expected during high tide, especially late Tuesday night into Wednesday, when water levels may rise enough to briefly cover roads, flood low-lying neighborhoods, and cause delays in busy shore towns.
High Rip Current Risk Along Beaches
Along with the flooding risk, officials have issued a high rip current warning from Sandy Hook to Cape May in New Jersey, and from Lewes to Bethany Beach in Delaware. Lifeguards are warning the public not to enter the water until conditions improve, as the strong currents and rough surf pose a serious danger to swimmers and surfers.
Flood-Prone Roads at Risk of Closures
Several flood-prone areas are especially vulnerable, including:
Route 47 near Wildwood
Roads along the Christina and Brandywine Rivers
Riverfront neighborhoods in Wilmington and Philadelphia
These areas may see temporary closures during peak tide levels, especially around early morning and evening high tides.
Safety Tips for Residents and Visitors
To stay safe during this period of coastal flooding and dangerous surf, officials are urging residents and travelers to:
Avoid driving through standing or flooded water
Secure outdoor furniture and loose items
Stay away from the surf and tidal shorelines
Monitor local weather updates and check tide forecasts
Conditions Could Linger Into Thursday
While the worst impacts are expected on Wednesday, forecasters say strong onshore winds could continue into Thursday, possibly extending the flooding threat into the next high tide cycle.
