NEW YORK — Tens of millions of residents along the I-95 corridor are bracing for a “blockbuster” nor’easter after a dramatic Saturday forecast shift turned a routine winter storm into a life-threatening blizzard. As of Saturday evening, February 21, 2026, the National Weather Service has issued Blizzard Warnings for a massive swath of the Northeast, including New York City, Philadelphia, and Boston, affecting nearly 30 million people.
The storm is expected to undergo bombogenesis—rapidly intensifying into a “bomb cyclone”—as it moves off the coast Sunday night, bringing whiteout conditions and potentially historic snow totals.
The “Dramatic Shift”
Just 24 hours ago, meteorologists were predicting a manageable 4-to-8-inch snowfall. However, new data shows the storm tracking closer to the coast and tapping into intense Atlantic moisture, leading to a massive upgrade in expected totals.
- New York City: Facing its first blizzard warning since 2017. Mayor Zohran Mamdani has warned of 12–18 inches of snow, with a “worst-case” potential for two feet.
- New Jersey & Long Island: Forecasts now call for 18–24 inches in some areas, coupled with wind gusts up to 70 mph.
- The “I-95 Corridor”: From Philadelphia to Boston, 12–18 inches is now the baseline expectation.
States of Emergency Declared
Governors across the region have acted quickly as the forecast solidified on Saturday afternoon:
| Official | Location | Action Taken |
| Gov. Kathy Hochul | New York | Declared a State of Emergency for 22 counties, including NYC and Long Island, effective Sunday morning. |
| Gov. Mikie Sherrill | New Jersey | Declared a State of Emergency effective at noon on Sunday, citing “severe blizzard conditions.” |
| Gov. Ned Lamont | Connecticut | Urged residents to prepare for a “long-duration event” through Monday night. |
| Mayor Zohran Mamdani | New York City | Advised all residents to vacate low-lying areas prone to coastal flooding and stay off roads. |
Timing the “Bomb Cyclone”
Conditions are expected to deteriorate rapidly throughout the day on Sunday, with the most dangerous period occurring overnight.
- Sunday Morning: Rain and wet snow develop from D.C. to New York.
- Sunday Evening: The storm “bombs out” off the coast; precipitation turns to heavy, wind-driven snow.
- Sunday Night/Monday Morning: Peak intensity. Snowfall rates of 1–3 inches per hour combined with 60 mph winds will create zero-visibility whiteouts.
- Monday Afternoon: The storm begins to taper off from south to north, though drifting snow will continue to plague New England.
The Triple Threat: Snow, Wind, and Sea
Authorities are warning that this is not just a “snow event,” but a multifaceted disaster risk:
- Power Outages: The combination of heavy, wet snow and extreme wind gusts is expected to down trees and power lines across the coastal Northeast.
- Coastal Flooding: A “Storm Warning” is in effect for coastal waters, with high tide late Sunday night threatening significant beach erosion and flooding in shoreline communities.
- Travel Shutdown: Over 2,000 flights have already been canceled for Sunday and Monday at JFK, Newark, and Boston Logan.
“Two days ago we were expecting a run-of-the-mill February storm… but over the last 24 hours, this forecast has shifted dramatically and New York State is in the crosshairs.” — Gov. Kathy Hochul, Feb 21, 2026
