Executive Summary
A polar vortex breakdown is sending brutal cold, ice, and snow across the US and Europe, straining power grids, transport, and household preparedness
- A stretched polar vortex is driving a major winter outbreak across the US and parts of Europe
- The storm brings freezing rain, heavy snow, and life-threatening cold across a wide area
- Officials warn of catastrophic ice buildup, long power outages, and impassable roads
- More than 2,700 weekend flights were canceled as travel disruptions mounted
- At least 16 states and Washington DC declared states of emergency and opened warming shelters
- Meteorologists link the event to Arctic warming, low sea ice, and heavy Siberian snowfall
- The cold risk is expected to last into early February, with extreme wind chills in the Northern Plains and Upper Midwest
Quick Facts
- What: A polar vortex breakdown drives severe winter weather
- Where: Continental United States and parts of Europe
- Why: Arctic warming and low sea ice destabilized the jet stream
