The Met Office has issued an ice warning for much of Devon for Saturday and Sunday.
The yellow-graded weather warning, the lowest kind issued by the Exeter-based agency, is in place for parts of North Devon including Exmoor, Torridge, South Molton, Chulmleigh, the A361 North Devon Link Road and the A377.
It is in place from just after midnight until 11am on Sunday.
A spokesman for the Met Office said: “The wintry weather will continue through the weekend, albeit in a less severe form.
“The continuing low temperatures will mean that lying snow will remain and ice will become a problem, both were snow partly melts, or in the southwest of England and Wales where heavier rain fell early on Friday.
“Although some further slight snowfalls are likely, with 1 to 2cm of fresh snow in a few places, the focus switches to ice, with sub-zero temperatures persisting over existing snow cover for many areas and spreading back into parts of the South West towards daybreak on Saturday.
“The public should be aware of the risk of localised disruption to transport during this spell of wintry weather.”
