The UK could be facing another extreme bout of snowfall similar to the 'Beast from the East' that battered the country back in 2018.
A Sudden Stratospheric Warning (SSW) has potentially been picked up in new long-range forecasts by the Met Office, which could trigger the spell of bad weather.
This major weather event causes the air high up in the stratosphere to warm up, causing the jet stream to veer off its normal route - resulting in bitterly cold conditions.
