Meteorologist PettusWX reported a Blizzard Warning in effect for coastal regions from Boston down to southern parts of Delaware during the two-hour period ending 6:15 PM UTC on February 21, 2026, according to his X post. Winter Storm Warnings and Watches cover more inland areas, with additional winter storm alerts for parts of the Appalachian mountain region. This update from PettusWX details a wide variety of winter weather alerts across the Northeast ahead of the upcoming blizzard, building on prior National Weather Service Blizzard Warnings for the New York City area forecasting 13-18 inches of snow from Sunday 6:00 AM to Monday 6:00 PM UTC, as shared by NYC Councilmember Mark Levine earlier today. The expanded warnings align with earlier forecasts from the 12Z NAM model predicting historical blizzard conditions with 24+ inches for many areas including NYC, as reported by Meteorologist BlediB7 in the 29 minutes ending 4:15 PM UTC.
