Hundreds of schools across Wales and southern parts of England are closed due to snow and icy conditions.

More than 500 schools are shut in Wales, with about 200 in Berkshire, 250 in Wiltshire and 300 in Buckinghamshire also closed.

The Met Office has two yellow warnings in place for snow and ice in parts of England, Wales and north and eastern areas in Scotland.

Over 35 flights at Heathrow have been cancelled and Bristol Airport is shut.

Flights have been suspended until 12:00 GMT while snow is cleared from the runway.

British Airways, which cancelled dozens of flights from Heathrow Airport on Friday morning, advised customers to check their flight status and said people due to travel on short-haul flights were being offered the option to postpone their journey.

Meanwhile, the Met Office has warned of “treacherous driving conditions” in some southern areas.

The South West was worst affected on Thursday night, with snow depths of 12cm (5in) recorded in Bodmin, the Met Office said.

Parts of Cumbria have seen 8cm of snow, while there was 7cm recorded in Inverness-shire and 5cm in Powys.

Sammy Wheeler, who runs the Jamaica Inn, said some of those who spent the night had walked “a good three, four or five miles” through the snow to get there.

All 36 rooms at the pub were occupied overnight, with some shared by strangers. Two makeshift dormitories were also set up in the restaurant and lounge areas to help look after the guests, who included children and an eight-month old baby.

“People were incredibly high spirited,” Ms Wheeler said.

“We kept the kitchen open all night and people were playing games in the bar until the early hours in the morning.”

Paula Martin, chief executive of Cornwall Air Ambulance, was in one of the cars that got stranded on the A30.

“I got within two miles of home and the snow arrived very quickly and very suddenly,” she said.

“Within minutes the A30 very quickly became impassable, especially for the lorries – and it went from bad to worse.”

What warnings are in place?

There are yellow warnings for snow and ice until lunchtime on Friday in large parts of Wales and England, including London, and northern and eastern Scotland.

They warn of some snow, but not prolonged falls, and say some stretches of road will be icy.

An amber warning means there is a likelihood of impacts from severe weather including a potential risk to life and property. People should be prepared to change their plans to make sure that everybody is safe.

Yellow warnings are issued for low level impacts including some disruption to travel. People should check the latest forecast and check how they might be impacted.
