Delaware (October 9, 2025) — A significant coastal storm is expected to impact Delaware and New Jersey from Sunday, October 12, through Monday, October 13, bringing the potential for moderate to major coastal flooding, strong winds, heavy rainfall, and dangerous marine conditions, according to the National Weather Service and TVDelmarva Chief Meteorologist Hunter Outten.
Coastal areas along the Atlantic coast and Delaware Bay are at the highest risk for flooding, particularly during high tides. Preliminary guidance from the NWS indicates that flooding could extend beyond standard tide forecasts, with potential for beach erosion and damage to structures along the shoreline. Residents in low-lying areas are urged to take precautions and prepare for possible impacts.
Strong northeast winds are expected along the coast, with gusts over 45 mph likely and the possibility of gusts exceeding 55 mph depending on the storm’s intensity and track.
Offshore waters are expected to see significant waves, creating hazardous conditions for marine traffic. A storm watch has been issued for Delaware Bay waters from East Point, New Jersey, to Slaughter Beach, Delaware, in effect from 6 p.m. Sunday to 8 p.m. Monday. Small craft advisories are also active through Thursday for the same area. The storm is forecast to bring heavy rainfall to areas along and south or east of the I-95 corridor. Rainfall totals could reach two inches or more in some locations, increasing the risk of localized flooding in urban areas. Actual rainfall amounts will vary depending on the storm’s track and intensity.
TVDelmarva Chief Meteorologist Hunter Outten warned, “Serious concerns of local water ways around the Virginia Capes, Indian River Bays, and the Delaware Bay of tidal surges of 3-5 feet are in the realm of possibility during Sunday’s high tide cycle. With already stressed beaches from the recent passes of 3 hurricanes sending swells towards Delmarva, it’s a recipe for widespread significant coastal flooding for area residents along tidal waterways.”
The National Weather Service emphasizes that residents and visitors in affected areas should take precautions to protect life and property. Officials advise securing outdoor items, avoiding travel through flooded areas, and staying informed through local weather updates. Preparations are recommended to mitigate risks from flooding, strong winds, and storm surge.
This storm adds to a season of active coastal weather in the region, with forecasters cautioning that timing and intensity remain subject to change. Residents are encouraged to monitor updates from the NWS and follow guidance from local authorities.
