London is currently under a ‘be prepared’ warning for ice after snow fell and temperatures plummeted over the weekend.

At the moment it looks like things are not too bad on the Tube network with just minor delays between Amersham/Chesham and Watford to Harrow-on-the-Hill as a result of a signal failure.

There were also problems on London Overground because of another signal failure causing the line to be part suspended and resulting in severe delays.

But as far as snow and ice go, it’s not too bad.

People are being warned to allow more time for their commutes into work and things seem a little busier than normal on roads heading into London.

The RAC has told some people – particularly in the Midlands – to expect their journeys to take up to three hours longer.

TfL has warned that some services may be affected later on.

Dozens of flights are showing as cancelled at Heathrow – with the airport saying the disruption is ‘due to crew and aircraft being out of position’.

British Airways says it has reduced its flight schedule from Heathrow due to the forecast of continued bad weather.

Passengers are being advised to check the flight status before they travel to the airport. Seven flights have been cancelled at Edinburgh airport, while Manchester airport has 13 departures listed as cancelled.

Pete Williams, the RAC’s road safety spokesman, said they are expecting 11,000 breakdowns on Monday, a figure which is 20% above the seasonal norm.

‘I think the big thing is people are not going to leave enough time,’ he said.

‘Journeys will take two to three times longer. It’s going to be treacherous driving conditions.’
