Snow has been forecast for parts of West Somerset over the weekend as the region remains gripped in a big freeze.

The Met Office predicts the chance of snow at up to 60 per cent for Dulverton between 4am and 7am on Saturday, and there is a 50 per cent risk of wintry showers in the early hours of Sunday.

The forecast comes as the Exeter-based agency updated its Yellow Warning for ice covering western areas of the UK, including part of Exmoor, to noon on Sunday.

Frost and fog is forecast for the region on Friday night, with a minimum of minus 7C.

Travel Somerset is expecting light show showers arriving from the west overnight.

Saturday is expected to see a maximum of 5C and Sunday to Tuesday will remain cold with sunny spells and wintry showers.

The Met Office warned disruption is likely due to icy surfaces, and there is a risk of injury from slips and falls on icy surfaces.

It said the weather was likely to cause icy patches on untreated roads, pavements and cycle paths.

Temperatures are expected to plummet below zero again overnight on Friday into Saturday morning.

Wellington was forecast minus 2C, with minus 4C expected at Dulverton, although Minehead was due to stay above freezing into Saturday.

In many places, the temperatures will only rise above freezing during the day through next week.

Travel Somerset, which issues updates on behalf of the county’s highways department, said gritters were out again on Friday afternoon on all routes, and would also be gritting in the morning.

A statement said they were expecting some light snow showers drifting in from the west during the night, resulting in a thin covering.

The road surface temperatures are expected to drop to a minimum of 5.7C.
