The National Weather Service New York office upgraded Winter Storm Watches to Blizzard Warnings along the coast and to Winter Storm Warnings elsewhere between 10:45 AM and 11:45 AM UTC on February 21, 2026, as a strong nor'easter approaches Sunday into Monday, according to an official NWSNewYorkNY X post issued during the reporting window. This upgrade builds on Blizzard Warnings previously expanded to the Mid-Atlantic region earlier this morning, forecasting 12-20 inches of snow accumulation amid high winds, as reported by meteorologist Faytuks on X between 9:15 AM and 10:45 AM UTC. The new statement specifies heavy snowfall impacts from the nor'easter across the area. The prior warnings for New York City, Long Island, southeast New York, and southern Connecticut predict 13-18 inches of snow and wind gusts up to 55 mph from Sunday 6:00 AM to Monday 6:00 PM UTC, per PIX11News reporter Mike Masco's earlier report. Expected impacts include near-zero visibility, whiteout conditions, life-threatening travel, power outages, and tree damage, particularly Sunday night into Monday.
