Meteorologists forecast a polar vortex collapse for mid-March. North America expects extreme winter weather. This polar vortex collapse winter weather may cause travel disruptions. The Polar Vortex Collapse Impact could reach the UK and Europe too.
Meteorologists predict cold temperatures for the US and Canada. A sudden stratospheric warming (SSW) event will likely trigger the polar vortex collapse. This warming pushes Arctic air southward. The polar vortex collapse weather pattern brings severe conditions.
The collapse marked the second in 2025. The last one in February caused deep freezes, bringing snow and sub-zero temps to millions. The Polar Vortex Collapse Impact may repeat this chaos soon.
How It Happens
A polar vortex collapse occurs above Earth’s surface. In just two days, temperatures rise by 50 degrees at 10-50km up. This SSW weakens the jet stream and releases cold polar air into North America, experts say.
AccuWeather’s Paul Pastelok predicts displacement. He told The Independent that the polar vortex will likely shift toward Europe and eastern Canada. Timing is uncertain for the US, Pastelok added. Meteorologists expect polar vortex collapse weather shifts from late March to early April.
A jet stream split remains possible but rare. A full split could impact four to seven weeks. Pastelok favors a shorter displacement. Central and eastern North America will experience this polar vortex collapse winter weather.
Wider Effects
The Met Office warns the UK of potential cold. They said, “Weather impacts might emerge weeks later.” SSW events favor blocked patterns. Colder conditions could hit Britain due to the Polar Vortex Collapse Impact.
The polar vortex refers to a large low-pressure area. It spins around Earth’s poles with the jet stream. When weakened, it loses stability and spills Arctic chill south. Extreme and unpredictable polar vortex collapse weather is the result.
