A powerful offshore nor’easter is pounding the East Coast from the Carolinas into New England, placing more than 30 million people under wind advisories and another 30 million under coastal flood alerts through the weekend of Sept. 26 and 27, 2026. The slow-moving system has washed out coastal highways, triggered states of emergency in New York and New Jersey, and left tens of thousands of residents without power.
Severe Flooding and Travel Disruption Along the Mid-Atlantic
The storm’s heavy surf and high tides began impacting the Outer Banks of North Carolina on Sept. 24, washing out a section of the coastal highway before pushing into Virginia on Sept. 25 and reaching New Jersey by Sept. 26. According to Brian Hurley, a meteorologist with the Weather Prediction Center, moderate to major flooding is forecast at more than 40 gauges between North Carolina and Long Island. Governors in New York and New Jersey declared states of emergency ahead of the weekend intensification. Officials in New York City warned residents of potential basement flooding and power outages, while the Federal Aviation Administration cautioned that strong winds could disrupt flights at all three major New York-area airports. Reuters reported that by Saturday afternoon, about 425 U.S. flights had been canceled and 1,338 delayed. PowerOutage.com recorded more than 50,000 customers without power across New York, Connecticut, and New Jersey on Saturday evening.
Equinox Tides Compound Coastal Risks
The flooding threat is heavily magnified by astronomical factors, as the storm arrives during a full moon coinciding with an equinox, creating naturally highest monthly tides known as king tides. Hurley noted that even without the storm, normal tides would be elevated. The offshore system’s onshore winds are pushing water into streams and waterways, preventing normal ocean drainage while heavy rains fall upstream.
“If we had no storm at all the tides would be higher than normal,” Hurley said. He explained that the storm will linger through three high tide cycles, which may cause water to have nowhere to go and result in a compounding problem where each subsequent high tide is even higher.
AccuWeather warned of major risks from the Jersey shore into southern Long Island, Cape Cod, and eastern Massachusetts, forecasting wind gusts up to 80 mph and 4 to 8 inches of rain between Long Island and Boston. Saturated soils have increased the vulnerability of trees to toppling. The severe weather also forced schedule changes, including moving a Major League Baseball game between the Chicago Cubs and Boston Red Sox to Tropicana Field in St. Petersburg, Florida, alongside the cancellation of concerts by Ed Sheeran, Alicia Keys, and Lenny Kravitz.
Tragic Fatality and Ongoing Weekend Outlook
As the nor’easter drifted near the New Jersey coastline, regional impacts turned fatal in New York City, where New York City Housing Authority employee Leighton Brown, 56, died after a tree fell on him in Brooklyn, according to city officials. AccuWeather and the National Weather Service reported wind gusts exceeding 70 mph in Surf City, New Jersey, alongside 4 to 6 inches of rainfall across coastal cities from New Jersey to Massachusetts. While the highest winds begin to transition, NOAA’s Weather Prediction Center warned that dangerous beach conditions, strong rip currents, rough surf, and significant beach erosion will persist from the Carolinas through southern New England through at least the evening of Sept. 27. Additional wind gusts up to 40 to 50 mph remain possible from New Jersey to Long Island, threatening further power outages as the weakened system continues to impact the Northeast into early next week.
