The last weekend of October is set to deliver a coastal storm to the area, with potential for soaking rain, gusty winds and some coastal flooding, forecasters say.
The system would be moving across the region from Friday night into early Sunday, the National Weather Service said, though timing and other elements are subject to change.
As of Tuesday evening, the expectation was for the region overall to see an inch to an inch and a half of rain, most of it arriving Saturday, along with gusts from the northeast of 30 to 40 mph. That could lead to some downed trees and branches, that could result in isolated power outages.
"It should be a typical coastal noreaster with strong winds, periods of heavy rain and probably some coastal flooding because of onshore winds and the moon’s phase ... it is full on Wednesday," said News 12 Long Island meteorologist Bill Korbel in an email.
There also could be widespread minor coastal flooding, with localized moderate flooding along the South Shore of Nassau County and western Suffolk.
Still, with the system days away, that picture could shift, said the weather service, which puts its confidence in the forecast at this time as medium.
Long Islanders will want to “keep monitoring the weather situation,” as details are fine-tuned closer to the event, said Brian Ciemnecki, weather service meteorologist in Upton.
Still, the potential for snow should not be a worry for Long Islanders, as colder areas of northern New York and parts of northern New England would have better chances for that, the National Weather Service’s Eastern Region, headquartered in Bohemia, said in a tweet.
Also, this “first nor’easter of the season” is expected to tap into moisture from the remnants of Hurricane Willa.
After Willa, which was expected to make landfall Tuesday evening on the west coast of Mexico, moves inland and weakens, “deep moisture” from its remnants will bring “a swath of heavy rainfall” over northern Mexico and areas of Texas, the National Hurricane Center said.
Ultimately, that moisture will also help fuel the system that will be moving up the East Coast.
