UPDATE: The Met Office is warning of snow on Sunday in Devon with strong winds and "temporary blizzard conditions" possible.

The warning has been expanded to include Monday as "more persistent spell of rain, sleet and snow affecting Wales, the Midlands and southwest England" is expected on Monday as a very cold air mass spreads south from Scotland..

The Met office adds that this is more uncertain and further updates are likely in the coming days.

Forecasters say that snow showers may spread along eastern and western coasts of England and Wales and that the public should be aware of the potential for disruption.

The showers will be "associated with strong winds so drifting and temporary blizzard conditions are possible as well as icy stretches".

The Met Office chief forecaster said: "Frequent showers are likely to form in this airmass, primarily affecting northern parts of Scotland and Northern Ireland but also running along eastern and western coastal districts of England and Wales at times.

"With the cold air snow is likely to accumulate even to low levels wherever showers affect. 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.

"There is the potential for disruption throughout this period due to the accumulating snow and ice but also with temporary blizzard conditions leading to very difficult driving conditions.
