Nor'easter Slams Northeast, Killing One and Cutting Power to Thousands A nor'easter battering the Northeast has killed a man in Brooklyn, left over 100,000 without power, canceled hundreds of flights and prompted states of emergency in New York and New Jersey. Millions of people across the Northeast, including New York City and Boston, face dangerous coastal flooding, beach erosion, strong winds and heavy rainfall as a nor'easter strikes the region this weekend, the National Weather Service warned. The storm has killed at least one person, a 56-year-old man in Brooklyn hit by a falling tree on Saturday, and left more than 100,000 households without power across New Jersey, Massachusetts, Delaware and New York, according to the outage tracker PowerOutage. Several events were canceled, including the Global Citizens Festival set for Saturday in New York City's Central Park and Ed Sheeran's concert at Gillette Stadium in Massachusetts. More than 450 flights were canceled and 3,000 delayed on Saturday.Forecasters said conditions will peak from Saturday into early Sunday, though strong winds, rough surf and coastal flooding will linger into Monday, with rain showers continuing on and off.New York and New Jersey Hit HardestThe nor'easter has brought dangerous wind gusts and coastal flooding to the entire Northeast, but the New York City metropolitan area and New Jersey are expected to take the brunt, according to forecasters.The National Oceanic and Atmospheric Administration warned that the strongest gusts and widespread coastal flooding will most likely occur near the waterfront and shorelines of New Jersey, New York City and Long Island. The worst flooding is expected during the daytime high tide cycles on Saturday and Sunday.Flooding will also extend inland from the waterfront along tidal rivers and bays. By Friday afternoon, both New York and New Jersey had declared a state of emergency.In New York, Governor Kathy Hochul placed New York City and Westchester, Nassau and Suffolk counties under a state of emergency and issued a coastal flood warning for Long Island, New York City and the lower Mid-Hudson region.The worst flooding, the governor's office said, is expected along the south shore of Long Island, as well as parts of lower New York Harbor and coastal areas of the Bronx, Westchester and northern Nassau County along the Long Island Sound.In New Jersey, Governor Mikie Sherrill declared a state of emergency for eight counties expected to face the most severe impacts: Atlantic, Burlington, Cape May, Cumberland, Middlesex, Monmouth, Ocean and Salem. Showers and thunderstorms, including some severe ones, may produce localized heavy rain from the Southern Plains to the upper Mississippi Valley, NWS forecasters said.How Long the Storm Will LastThe latest NWS update warns that high tide cycles through Sunday afternoon will bring potential for moderate to locally major coastal flooding along most of the local coastline, with the worst likely to hit the southern and eastern bays of Long Island.Some two to four inches of additional rainfall is expected across New York City, Long Island and southern Connecticut, while 1.5 to 3 inches are expected elsewhere. Widespread minor urban, poor drainage and small stream flooding, with isolated flash flooding, is likely through Sunday night, forecasters said.The nor'easter is expected to gradually weaken on Sunday, though its impacts will continue into Monday, including on-and-off rain showers, gusty winds and some coastal flooding.John Davitt, chief meteorologist for Spectrum News NY1, wrote on X that the storm will not leave the region until Monday night, referring to New York City, and added that waves of rain are coming. In the city, strong to damaging winds will peak on Saturday night into Sunday morning, according to the city's NWS branch.Safety Advice for ResidentsBoth Sherrill in New Jersey and Hochul in New York urged residents to take the weather warning seriously and be cautious over the next couple of days.Sherrill said in a statement that she urged all New Jerseyans to take the storm seriously, stay safe and be prepared, asking them to charge phones, secure loose items outside, stock up on food and water, and stay off the roads if possible.She added that anyone who needs to travel should plan ahead and stay up to date on alerts, as conditions can change quickly, and never drive through flooded roads.Hochul said residents should take the storm seriously, stay alert and avoid unnecessary travel. NOAA recommends that residents of affected areas make sure they have food, water, medications and other basic necessities for themselves, their families and their pets to sufficiently ride out the storm and its aftermath.
