Here's the latest from the Met Office
A major weather incident could cause some "changeable" weather towards the end of this month, the Met Office has confirmed.
But sometimes the Polar Vortex can break down altogether - which is known as a Sudden Stratospheric Warming and has been linked to many cold snaps in recent years, including 2018's infamous 'Beast from the East'. The latest weather predictions reveal that another "major" Sudden Stratospheric Warming is now likely to take place from mid-February.
The head of long-range forecasting at the Met Office, Professor Adam Scaife, said that there is now over an 80% chance of a major Sudden Stratospheric Warming occurring. He explained that while the impact of this will become clearer nearer the time, its effect on UK weather will "most likely" be felt in late February and into March.
