South Western Railway has already warned passengers that trains may be cancelled on Friday morning while work is done to check and clear the tracks.

By mid-afternoon on Thursday, the snow had hit the south-west. Devon and Cornwall police said it was causing disruption on the A30 near Jamaica Inn at Bolventor. As darkness fell about 100 vehicles were trapped on the same road at Temple on Bodmin Moor, where the Met Office said snow was up to 12cm deep.

The AA advised motorists to carry a winter survival kit containing items such as an ice scraper, de-icer and a blanket. A spokesman said: “People should also take it slow, as stopping distances are 10 times longer. Gentle manoeuvres are the key to safe driving in ice and snow.”
In Wales, Dyfed-Powys police asked for people to think twice before contacting the force. Head of specialist operations, Supt Craig Templeton, said: “We have been busy planning for the adverse weather so we can continue to serve our communities in the way they expect.
“To help us do this, we are asking the public to consider their options before contacting us, as in some cases, other organisations may be better placed to help you. For example, if you are calling about a tree or power/telephone pole that is down, you should only call us to report this if there is a significant risk to others, or there has been a collision and someone is injured.”
In Caerphilly, South Wales, a gritting truck overturned on ice, despite the road being gritted three times in one day.
Councillor Sean Morgan, cabinet member for highways, said: “This was a very experienced driver, but between the third and fourth gritting treatments the hill had iced over and this demonstrates that road surfaces can still be dangerous, even when gritted.”
