Overview

 
A powerful nor’easter is forecast to sweep across Long Island and New York City over the weekend, bringing a mix of heavy rain, gusty winds, and coastal flooding. While some dryness may finally get addressed, low-lying areas and shorelines are at risk for nuisance to moderate flooding. 

What to Expect

 Meteorologists anticipate 1.5 to 3 inches of rain over the duration of the storm, with coastal zones likely seeing the greatest totals. The National Weather Service is warning that sustained winds of 25 to 35 mph, with gusts up to 60 mph, may batter parts of eastern Long Island and spots along the South Shore.

Because of high tides, minor to moderate coastal flooding is expected, especially in back bays and shallow zones around the Great South Bay and areas like Lindenhurst. Meanwhile, exposed shorelines could experience erosion from wave action and storm surge.

Voices on the Storm

“We’re looking at an approaching coastal storm that’s going to bring a couple different hazards to the island,” said Dave Radell, Science and Operations Officer at the National Weather Service.


Radell also noted,

“The second hazard will be some rainfall, which actually might be more beneficial than not because it’s been rather dry.”


He cautioned residents to secure outdoor furniture, watercraft, and any loose items before conditions deteriorate. He also stressed avoiding driving in heavy rain and high wind periods.
 
PSEG Long Island’s Michael Sullivan, VP of Electric Operations, assured the public that the utility is preparing for potential impacts:

“Our crews will work to safely restore any outages as quickly as conditions will allow,” he added.
 Sullivan also emphasized that residents should treat any downed line as “live” and call 911 or PSEG’s 24-hour service line to report it.

Timeline & Impacts

  • Saturday–Sunday: Rain intensifies and wind ramps up, especially along eastern Suffolk and the South Shore.
  • Sunday night into Monday: Highest risk period for wind gusts, flooding, and erosion.
  • Monday afternoon: Storm should begin to weaken, though residual coastal flooding and light precipitation may linger.
