BBCMany people on the Isle of Man are expected to wake up to a blanket of snow on Sunday.
An amber severe weather warning – the second highest level – has been issued by Ronaldsway Met Office and it will be in place from 23:00 GMT on Saturday until the early hours of Monday morning.
Forecasters warned “significant amounts of snow” could accumulate on higher ground on Sunday, including the possibility of up to 11 inches (28cm) in places more than 800ft (243m) above sea level.
The Manx government said routes above 500ft (152m) would be pre-salted on Saturday evening. Both the Mountain Road and Sloc Road are expected to be closed from 22:00.
Forecasters also warned of “overhead power line icing” and the risk of drifting snow in blizzard conditions.
Lower-level areas in the west of the island could see sleet or snow, they added.
Members of the public have been asked to grit local driveways and pathways using salt bins as required.
Motorists are urged to exercise caution and “drive to the conditions”.
The situation will be monitored by the island’s adverse weather group over the weekend.
Decisions about whether schools can open will be made by 07:00 on Monday, the government said.
