Met Office warns of possible disruption and difficult driving conditions with potential of heavy snow on Sunday.
A snow warning has been issued for North Devon for Sunday with blizzard conditions possible, the Met Office has said.
It said there was potential for disruption and difficult driving conditions as the showers affected western coasts, with strong winds leading to possible drifting snow.
“With the cold air snow is likely to accumulate even to low levels wherever showers affect,” said a chief forecaster.
“Periods of enhanced snowfall are possible within this general flow but details of these are very uncertain at this time.
“As such this alert is likely to be updated and refined in the coming days to better represent individual features.”
