Transport bosses have moved to assure Londoners the capital will not grind to a halt as commuters braced themselves for five days of snow showers.
Transport for London (TfL) said staff have done “everything possible” to prepare as forecasters warned that freezing temperatures could spark travel chaos and power cuts across the UK.
A ferocious blast of cold air from Siberia, nicknamed the Beast from the East, is forecast to bring disruptive weather conditions as Britain is gripped by its coldest February week in five years.
And the Met Office said snow is expected to fall on London and the south-east on Monday, Tuesday, Wednesday, Thursday and Friday this week.
Gareth Powell, TfL managing director of transport surface, said “well-rehearsed” procedures are in place to minimise the consequences of wintry conditions.
He added: “We’re working with London councils and the emergency services to develop in-depth plans and keep the Capital moving. We would encourage customers to check before they travel.”
Local councils in the capital also working with TfL to ensure key roads and cycle routes are salted and cleared when necessary as they come together to tackle what could be a chaotic week ahead.
It comes as Met Office meteorologist Alex Burkill said he could not rule out snow falling “pretty much anywhere” in the UK in the coming days.
Speaking to the Standard on Sunday, he warned motorists of potential delays on the M25 during the Monday morning rush hour when the first of the wintry showers is expected.
Mr Burkill said: “Tonight [Sunday night] it’s going to be cold again, dropping to -3C or -4C with largely clear skies for much of the night before tomorrow morning when we will see a few snow shower towards the east of London, including eastern parts of the M25.
“We could see some problems for the morning rush hour.”
Mr Burkill said snowfall could be “quite frequent and persistent” on Tuesday, while further wintry showers were expected for Wednesday.
“On Thursday, it will be windy and feel very cold. The temperatures will barely climb above freezing but it will feel as if it is between -5C or -10C,” he added.
“Significant snow is forecast overnight into Friday coming from the South West. A few cm of lying snow is expected for people waking up on Friday morning.”
The Met Office has issued yellow ‘be aware’ warnings for snow for Monday, Tuesday and Wednesday. It is currently considering upgrading Tuesday’s warning to amber and issuing another warning from Thursday night into Friday.
The warnings are in place for London and the south-east, the east of England, the Midlands, the north of England and Scotland.
