A spell of snow will move west across many parts of southwest Britain on Saturday night and Sunday. Snow will turn heavy in places on Sunday, and may last for much of the day across parts of southwest England. 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, especially in parts of southwest England, due to wet snow bringing down branches or other structures.
The warning has been extended west across Cornwall, and also until 2100; this later clearance most likely in the far southwest.
