As of February 1, 2026, a powerful bomb cyclone, designated as Winter Storm Gianna, is battering the U.S. East Coast. The storm is currently undergoing “bombogenesis”—a rapid drop in atmospheric pressure of at least 24 millibars in 24 hours—with some reports indicating an even more extreme drop of 35-40 millibars.
The storm is creating a “snow-squall” effect from the Carolinas through New England, leaving millions under blizzard warnings and extreme cold alerts.
Current Impacts & Regional Forecasts
The storm’s track is focusing its heaviest snow on the Southeast, while the Northeast faces hurricane-force wind gusts and punishing wind chills.
The Carolinas & Virginia: Historic Totals
For parts of the South, this is the most significant winter event in nearly a decade.
North Carolina: Raleigh and Greensboro are bracing for 8-12 inches of snow, potentially the heaviest since 2018.
South Carolina: Columbia is facing its largest snow threat since 2010.
Blizzard Conditions: Coastal areas of the Carolinas are reporting 70 mph hurricane-force winds, creating zero-visibility “whiteout” conditions.
The Mid-Atlantic & Northeast: Wind & Ice
While the storm is tracking slightly offshore, its reach is massive:
D.C. & Philadelphia: Expecting 1-3 inches of snow, but the primary threat is the Arctic blast. Wind chills are expected to plunge to -10°F.
New York City: Forecasted for 3-6 inches through Sunday evening. Frigid temperatures have turned existing snow into “snowcrete”—a rock-hard layer of ice that will not melt for days.
Boston & New England: Expecting 6+ inches in coastal areas with significant risk of coastal flooding during high tide.
Widespread Disruption
The storm has already caused significant fatalities and logistical chaos following a previous system earlier in the week.
Casualties: At least 85 weather-related deaths have been reported across multiple states since late January.
Travel: Over 1,800 flights were canceled by Saturday afternoon, with American Airlines cutting 16% of its schedule.
Power Outages: Approximately 190,000 residents in the Southeast are currently without power as heavy snow and wind snap lines.
Safety Warning: Meteorological data indicates that temperatures will remain 20-25 degrees below normal into next week. Pipes are at high risk of bursting, and hypothermia is a critical concern for those without adequate heating.
