A weather phenomenon bringing cold air from the Arctic could see temperatures plummet to -11C.
A major sudden stratospheric warming (SSW) event is taking place, and is expected to displace the polar vortex; a large region of cold, rotating air that encircles both of Earth’s polar regions.
As the atmosphere above the poles warms up dramatically, the 'vortex' of cold air spills out of the arctic region and moves elsewhere. Such an event led to the ‘Beast from East’ which froze the nation in 2018, causing 17 fatalities and bringing heavy snow, ice and strong winds.
