UK Braces for 'Beast from the East' Return?

Forecasting models suggest a potential for Sudden Stratospheric Warming (SSW) in early December, a phenomenon that could trigger a 'Beast from the East' weather event, bringing severe cold and heavy snow similar to 2018. This event occurs when rapid stratospheric warming alters wind patterns, drawing freezing air from the continent.

Currently, the UK is experiencing a significant cold snap with amber cold health alerts and yellow snow and ice warnings active. Scotland and North East England are most likely to see snow accumulations, with temperatures dropping well below freezing across the country. This harsh weather poses risks to vulnerable populations.

While SSW events do not always lead to extreme cold, they significantly increase the likelihood. The Met Office notes that an early-season SSW, like the one potentially occurring this year, raises the chances of a colder start to winter. However, precise impacts remain uncertain at this stage.
