The Met Office has warned of a “potential risk to life” as heavy snow is expected to hit most of the UK in the coming days.
Freezing weather sweeping in from Russia – known as “The Beast from the East” – is set to cause travel disruption and power cuts as Britain faces its coldest February week in five years.
Severe weather warnings have been issued for England, Wales, Scotland and Northern Ireland, with 20cm of snow predicted in places.
Temperatures are expected to drop close to -15C (5F) in some areas and forecasters say the icy conditions could last until the middle of March.
A yellow “be aware” warning is in place for Monday in eastern England, the Midlands, Yorkshire, the North East and London, with five to 10cm of snow expected.
A more severe amber alert – meaning there is a “potential risk to life and property” – has been issued on Tuesday for eastern England, the South East and London, Yorkshire, the Midlands and the North East, when up to 15cm of snow is predicted.
