Snow will continue across much of southwest England during Sunday afternoon, easing at times during the evening, but further spells of snow are likely into the early hours of Monday. Strong east or northeasterly winds will lead to some drifting of snow, especially over hills, with significant wind chill.
Travel delays on roads are likely, stranding some vehicles and passengers. Delays and cancellations to rail and air travel are likely. There is a good chance that some rural upland communities could become cut off. Disruption to power supplies is possible.
The warning has been updated to remove southeast Wales and parts of the West Country, where the snow is now easing, but extending the end time into the early hours of Monday.
