Nor’easter storm brings coastal flooding, as New York and New Jersey declare emergency

A powerful nor’easter is bearing down on tens of millions of residents across the northeastern United States this weekend, leaving a trail of early disruption that includes coastal flooding, widespread power cuts, travel gridlock, and a wave of canceled major public events.

The U.S. National Weather Service (NWS) has warned that the storm will reach its peak intensity on Saturday, bringing a hazardous combination of dangerous coastal flooding, unsafe beach conditions, high-speed winds, and heavy downpours to heavily populated areas stretching from New York City to Boston. Forecasts indicate precipitation and gusty winds will extend across a 900-mile stretch of the East Coast, from Virginia all the way north to Maine.

In response to the rapidly unfolding severe weather, state officials have declared states of emergency in both New York and New Jersey. New Jersey, in particular, is already grappling with early coastal inundation in multiple low-lying shore communities, where Saturday morning already found residential streets and local homes submerged in floodwater in Surf City and Manasquan. Forecasters added that this weekend’s coinciding full moon will exacerbate high tide levels, worsening the coastal flooding threat for at-risk areas.

The NWS issued an urgent alert for coastal communities, advising residents to “prepare immediately for significant inundation in low-lying areas near the shore, including roads underwater and impacts to homes and businesses.” In New York City, officials warned that wind gusts could reach up to 55 miles per hour (88 kilometers per hour) through the end of the weekend, raising risks of downed trees, snapped power lines, and extended power outages. New York Mayor Zohran Mamdani urged caution in a public video address to residents, saying, “Don’t travel if you don’t have to. Do not drive or walk through floodwater.”

The storm has already forced widespread cancellation of major scheduled events across the region. Ed Sheeran’s highly anticipated concert at Boston’s Gillette Stadium was scrapped for public safety, venue officials confirmed. Other called-off events include the Global Citizen Festival in New York City’s Central Park, which was set to feature headlining performances from Lauryn Hill, Wyclef Jean, and John Legend. Major league sports schedules have also been upended: the Boston Red Sox moved their scheduled weekend series game against the Chicago Cubs from Sunday afternoon to next Friday, while a professional MLS match between Red Bull New York and St. Louis City SC was also canceled.

As of Saturday morning, the storm had already knocked out power to nearly 150,000 households across the affected region, according to outage tracking site PowerOutage.us. Air travel has also been severely disrupted: the Federal Aviation Administration has urged all passengers to confirm their flight status with carriers before heading to airports, and flight tracking service FlightAware reported that more than 1,100 domestic flights have already been delayed, with another 400 flights completely grounded ahead of the storm’s peak.
