Severe weather warnings have been updated with heavy snow expected to hit Sheffield next week as a cold blast of air known as the 'Beast from the East' sweeps in from Russia.
Forecasters said the freezing weather could bring travel disruption and power cuts as the UK faces its coldest February week in five years.
Temperatures could drop as low as -15C in some places in the next few days and a snow warning for Tuesday has been upgraded to amber - meaning 'be prepared'.
