Fourteen schools in Surrey, mostly primary and junior schools, are closed in the face of icy conditions for commuters.

Blizzards will be confined mostly to the north and eastern parts of Scotland – where temperatures could drop to -6C – and will settle by around 11am.

Ipswich Quay, the Deben Estuary and Felixstowe could be swamped by flooding as early as 12.30pm.

In Lincolnshire, 100 soldiers have been deployed to “warn and inform” about potential risks from a flood surge expected at lunchtime.

EA chief executive Sir James Bevan told BBC Radio 4 he did not think the storm would be as powerful as the 1953 east-coast floods.

The deluge, described as the worst national peacetime disaster to hit the UK, killed 58 people in Canvey Island and 37 in Jaywick.

He said: “It’s very important to underline that there are two high tides today coming down the east coast, north to south.

“The first is coming in at the moment slightly under the height that we expected, the second, due this evening, may come out slightly higher than has been anticipated.

“And so we will stay very active throughout the day on the ground, we will continue to warn and inform the communities that are at risk, and I would like to urge everybody to remain vigilant and to continue to follow our flood warnings.”

Winds of up to 93mph were recorded in Yorkshire yesterday and up to eight inches of snow was forecasted to hit the UK until Saturday.

Tube stations, including Canary Wharf’s, were also closed yesterday due to flooding.

Up to seven inches in snow fell in Scotland overnight and snow gates on the A93 closed between Spittal of Glenshee and Braemar.

There were either accidents or traffic jams, in freezing conditions, along the M74, M77 and A9.

Met Office chief meteorologist Paul Gundersen said: “There's a chance any snow that settles could be disruptive to transport and possibly lead to interruptions to power supplies. Another potential travel problem could be the ice risk overnight.

"Forecasting snow is always challenging and there's often a fine line between whether it will rain or snow in a particular location depending on slight changes in air temperature. Keep an eye on the forecast and warnings for your area for the latest information."

RAC spokesman Simon Williams said: "Motorists all over the UK are facing very challenging driving conditions from the full array of winter weather.

"Driving in rain, snow and ice is a real danger so the best advice is to drive more slowly, leave far more space behind the car in front than normal, and expect the unexpected.
