STORM WATCH: Storm to drop 4-8 inches in Nassau, 8-14 inches in Suffolk
WHAT'S NEW: A winter storm watch is in effect starting 7 p.m. Friday, lasting through 7 p.m. Saturday for both Nassau and Suffolk counties.
WHAT'S NEXT: A major winter storm has an increasing chance of bringing significant snow for parts of Long Island, mainly eastern half of Suffolk County towards the East End. Light snow will begin late Friday, after the evening rush, but snow won't become steady until late Friday night (after 10 p.m.) and through the overnight hours. The storm will ramp up through the Saturday morning hours with heavy snow and winds gusting 30 to 50 mph. Snow will be heavy at times through the early afternoon hours before tapering off in the evening. Expect blowing and drifting snow, especially on the East End. Coastal flooding at high tide and beach erosion will also be a threat. Power outages may also be an issue with any down trees and power lines.
A total of 4-8 inches is possible in Nassau County and 8-18 inches in Suffolk. Totals will be adjusted over the course of the next 24 to 36 hours. The storm track has shifted slightly east, away from the island, so further adjustments to that track are likely to happen.
