The nor’easter that forecasters tracked toward New York all week has moved into the region, and coastal flooding is actively occurring. Power outages reached nearly 150,000 across the region by Friday evening, and coastal inundation is affecting low-lying neighborhoods, with National Weather Service warnings remaining active through Sunday.
The National Weather Service issued coastal flood warnings covering New York City, Long Island, and parts of New Jersey through Sunday. Expected inundation in vulnerable areas runs 1 to 2 feet above ground level, with locally up to 2½ feet in Jamaica Bay and Rockaways locations. Wind gusts reached 55 mph and higher in exposed coastal areas, and rainfall totals of 2 to 4 inches are forecast. Active flooding was reported in New Jersey coastal communities as of Friday.
Residents in low-lying coastal zones should move vehicles to higher ground and secure basement property before the next high-tide cycle. Commuters should check for service alerts on coastal rail lines and expect possible closures on coastal parkways. Avoid driving through flooded roads — even shallow floodwater can damage vehicles and make roads impassable. Check your NWS warning zone and local evacuation advisories before heading out.

Southern Queens, Staten Island, coastal Brooklyn, and the South Shore of Long Island face the greatest flood exposure. The NWS warning zone also covers Manhattan and parts of New Jersey. Inundation is expected to peak during morning high-tide cycles — extending the flooding window beyond the storm’s rainfall peak.
The NWS is warning of successive high-tide cycles extending coastal inundation beyond the initial rainfall peak. Warnings remain active through Sunday. The storm is coinciding with a full moon, which raises tidal levels and adds to flood risk in low-lying areas.
