The National Weather Service has now issued a blizzard warning for all of Long Island from Friday morning through Saturday afternoon.
The nor'easter is expected to bring upward of 10 inches to 15 inches of snow to the Long Island, with some areas possibly getting 16 to 18 inches. The forecast specifically for Southampton says to expect 7 to 11 inches of snow accumulation Friday night, and another 2 to 4 inches Saturday morning.
Wind gusts associated with this classic New England nor'easter will range from 30 to 40 miles per hour with howling gusts hitting 60 miles per hour. Downed trees, tree limbs and flying debris could also be part of the problem and winds will also cause whiteout conditions and possibly down power lines, creating power outages.
The National Weather Service forecasts the strongest winds and heaviest snowfall will occur from Friday evening into Saturday morning, although snowfall should begin early Friday morning before switching over to rain throughout the day.
The National Weather Service has also issued a coastal flood advisory for the Twin Forks.
A blizzard warning means severe winter weather conditions are expected or occurring within the next 12 hours. Falling and blowing snow with strong winds and poor visibilities are likely.
A technical "blizzard" would mean the following conditions over a period of three or more hours: sustained winds or frequent gusts to 35 miles per hour or higher with considerable blowing and/or falling snow that frequently reduces visibility to less than a quarter of a mile.
Patch will continue to monitor the nor'easter as it approaches Long Island.
