Coastal Flood Warnings cover parts of NJ, NYC, and Long Island; High Wind Warning for NJ and DE Atlantic coasts ahead of Friday second nor'easter
NWS issued Coastal Flood Warnings for parts of New Jersey, New York City, Long Island, and southern Connecticut. A High Wind Warning covers the New Jersey and Delaware Atlantic coasts with gusts to 60 mph. The nor'easter is forecast to stall near the Northeast through Sunday night, producing multiple high-tide flooding cycles through the weekend. Check weather.gov/phi and weather.gov/okx before driving to any waterfront access point.
Update October 16: The nor'easter arrived over the Northeast coast Friday as forecast. NWS has Special Marine Warnings in effect for portions of the coastal zone on Saturday, October 16, with wind gusts to 34 knots or greater. Small craft should stay in. The Coastal Flood Warnings and High Wind Warning from October 15 remain in effect for the stated zones, but expiration times and zone coverage may have changed since that report. Pull the current product for your specific zone at weather.gov/phi (NJ and DE) or weather.gov/okx (NY and Long Island) before any departure through Sunday night.
NWS Philadelphia/Mt. Holly (weather.gov/phi) issued a High Wind Warning for the New Jersey and Delaware Atlantic coasts with gusts to 60 mph ahead of the second nor'easter arriving Friday, October 16. NWS New York/Upton (weather.gov/okx) issued Coastal Flood Warnings for parts of New Jersey, New York City, Long Island, and southern Connecticut. The storm is forecast to stall near the Northeast through Sunday night into Monday. That stall produces multiple high-tide flooding cycles rather than a single overnight event; each successive tide reloads surge against the coast. Check both NWS sources for zone-specific expirations and re-issuances before heading to the water.
The High Wind Warning on the NJ and DE Atlantic coast means gusts that shut down departures from Jersey Shore inlets between Sandy Hook and Cape May and from Delaware ocean inlets from Rehoboth to Fenwick Island. This is the second system in two weeks to close the mid-Atlantic offshore corridor. The fall run window for bluefish, false albacore, and offshore striped bass that peaks in mid-October is being compressed by consecutive storms. NWS Mt. Holly marine zone products for NJ and DE are at weather.gov/phi.
The Coastal Flood Warnings for NJ, NYC, Long Island, and southern Connecticut mean that waterfront access roads, marina parking, and boat ramp staging areas in the affected zones may have standing water through multiple tidal cycles from Thursday evening through Sunday. Marina access conditions after a flooding event depend on how quickly individual sites drain between tides. A marina call before driving to a launch site is the right check. The zone text for the Long Island Sound corridor and the NYC area is at weather.gov/okx; NJ coastal flood products are at weather.gov/phi.
NWS products are the pre-launch check for every departure through Sunday night. Both weather.gov/okx and weather.gov/phi are updated as conditions change; a printed advisory expiry time does not mean conditions cleared, because NWS may re-issue before the clock reaches zero. Pull the current product for the specific zone before any departure.
