Delaware–New Jersey Weather Alert: Coastal Storm to Bring Heavy Rain and 60 MPH Wind Gusts
PHILADELPHIA, PENNSYLVANIA — A powerful coastal storm is forecast to impact New Jersey, Delaware, and southeastern Pennsylvania from late Saturday night through Monday, bringing heavy rainfall, strong northeast winds, and coastal flooding to the region. The system could lead to power outages, beach erosion, and significant travel disruptions as it intensifies along the East Coast.
Heavy Rainfall and Flooding Concerns
According to the National Weather Service in Mount Holly, widespread rainfall totals of 1 to 3 inches are expected, with localized amounts reaching up to 5 inches near the coast. Forecasters warn that urban and poor-drainage flooding is likely, particularly along the I-95 corridor from Philadelphia to Wilmington and Trenton.
Coastal communities including Cape May, Atlantic City, and Rehoboth Beach may face moderate to major tidal flooding during high tide cycles on both Sunday and Monday. Residents in flood-prone zones are advised to move vehicles to higher ground and prepare for possible road closures.
High Winds and Power Outage Risk
A High Wind Watch is now in effect for coastal counties of New Jersey and Delaware, where wind gusts could reach 55–60 mph. Inland areas may see gusts between 30 and 50 mph, especially across open stretches of road.
The National Weather Service warns that such winds could cause downed trees, power lines, and scattered outages throughout the region. Drivers should use caution on elevated bridges and highways such as Route 1 and the Garden State Parkway, where crosswinds may create dangerous travel conditions.
Marine and Coastal Impacts
Conditions offshore will deteriorate rapidly by Saturday night, with seas building to 15–20 feet and gale to storm-force winds battering the Delaware Bay and Atlantic coastal waters. The storm is expected to cause significant beach erosion and possible dune breaches, particularly along barrier islands.
Local officials urge residents along the coast to secure outdoor items, avoid unnecessary travel, and remain alert for emergency alerts or evacuation orders if conditions worsen. Those living near beaches or tidal zones should be prepared to take immediate action if flooding begins.
Outlook and Next Steps
The storm will gradually pull away from the coast late Monday, with rainfall tapering and winds beginning to ease by Tuesday morning. However, lingering gusts and high surf could persist into midweek. Meteorologists caution that additional systems could follow later next week as the fall storm pattern remains active across the Mid-Atlantic.
