The Met Office has issued a fresh 12-hour warning of snow for three regions across the UK as temperatures are set to plunge to -16C in some areas.
A yellow warning for snow and ice is in place for northern Scotland until midnight on Thursday and another snow and ice warning is in force for Northern Ireland until 11am on Thursday as sleet and snow showers are set to continue.
Meanwhile, a yellow fog warning has been issued for Northern Ireland until 9am on Thursday.
Met Office Chief Meteorologist, Steve Willington, said: “With low temperatures persisting across southwestern parts of England, sleet or snow will fall to low levels in parts of Devon, Cornwall, Dorset and Somerset through Wednesday afternoon and evening.
“At locations above 150 m, 2-5 cm is possible, but over the higher ground of Dartmoor and Exmoor up to 10 cm could accumulate.
“More widely across southern England, a dusting of snow, up to a couple of centimetres, is possible as the system moves eastwards.
“The snow could cause some disruption to the transport network during this evening’s rush hour.”
