UK weather: Heavy snowfall sweeps eastwards causing disruption
Heavy snow is sweeping eastwards across the UK, disrupting travel and leaving around 100 drivers stuck on a major trunk road in Cornwall, BBC reported.
The South West is worst affected - with teenage students at one college in Bodmin having to stay there overnight.
The freezing weather is moving across southern England and Wales, affecting Wiltshire, Hampshire, Sussex and Kent.
There are warnings of rail delays and flights cancellations into Friday morning.
The Met Office has warned of "treacherous driving conditions" in some southern areas.
There are two yellow warnings in place for snow and ice for large parts of the UK, lasting until Friday afternoon.
Snow depths of 12cm (5in) have been recorded in Bodmin, Cornwall, the Met Office said. Parts of Cumbria have seen 8cm of snow, while there was 7cm recorded in Inverness-shire and 5cm in Powys.
Disruption also includes:
An "intensive effort" is taking place to rescue motorists stuck on the A30 at Bodmin Moor, local police said.
Highways England said traffic was moving "very slowly forward".
Paula Martin, chief executive of Cornwall Air Ambulance, was in one of the cars which got stranded.
"I got within two miles of home and the snow arrived very quickly and very suddenly.
"Within minutes the A30 very quickly became impassable, especially for the lorries - and it went from bad to worse", she said.
My view: London is very cold
