STATEN ISLAND, N.Y. — Staten Island residents can expect rain Friday, with a more significant weather threat developing Sunday into Monday as a coastal low pressure system brings the potential for substantial snowfall, according to the National Weather Service.
No active watches, warnings or advisories are currently in effect for Staten Island.
Friday’s precipitation is expected to arrive between 7 a.m. and noon, with plain rain forecast along the coast, including Staten Island. The National Weather Service notes that liquid precipitation totals of a quarter to a half-inch is expected through Friday night, with the system exiting the area overnight.
Winds will be out of the east-northeast, with gusts reaching 15 to 20 mph during the day Friday before shifting to the west-northwest overnight.
The more consequential weather event arrives Sunday morning, when a developing offshore low pressure system is expected to bring snowfall to Staten Island and New York City. According to the National Weather Service, snowfall is forecast to begin Sunday morning, intensify through Sunday afternoon and evening, then taper off Monday into Monday night.
The National Weather Service’s probability models now place a 30% to 40% chance of six or more inches of snowfall across New York City and surrounding areas, a 10% increase from previous forecasts.
Forecasters caution that significant uncertainty remains regarding the storm’s exact track, which will be the critical factor in determining snowfall totals across Staten Island and New York City. A sharp cutoff in snow accumulation is expected, though its precise location has not yet been determined.
Strong winds are also anticipated Sunday night into Monday as the low deepens offshore, driven by an increasing pressure gradient.
Saturday is expected to offer a brief respite, with mainly dry conditions and no significant weather concerns for Staten Island or New York City before the Sunday system arrives.
The potential Sunday-into-Monday snowstorm represents the most significant winter weather threat of the extended forecast period. Residents should monitor subsequent National Weather Service updates as confidence in the storm’s track and intensity is expected to increase over the coming days, with planning for potential travel disruptions and hazardous conditions warranted for the Sunday-Monday timeframe.
