Scotland braced for a big freeze after Storm Caroline's 93mph gusts
Some 16,000 homes lost power while more than 100 schools were closed and trains on four railway lines were suspended.
Fair Isle, south of Shetland, recorded the highest guts, of 93mph, with 89mph at Sumburgh Airport on the southern tip of Shetland.
Fair Isle Bird Observatory warden David Parnaby said: “You can see it’s wild outside. We are used to fairly extreme conditions but this is more than we usually get.”
A separate snow and ice warning has been issued for all but the south-east of Scotland until 6pm on Saturday.
The Met Office warned of up to 20cm of snow from “increasingly frequent showers”, mainly in the north, and 2-5cm elsewhere.
A spokeswoman said: “Possible travel delays on roads, stranding some vehicles and passengers with possible delays and cancellations to rail and air travel. Some rural communities could be cut off and power supplies interrupted. Probably some icy stretches on some untreated roads, pavements and cycle paths.
“Some injuries from slips and falls on icy and snowy surfaces[expected].”
Temperatures are expected to fall to -1C in Edinburgh on Friday and Saturday night and -2C in Glasgow and Inverness. The coldest spots could include Aviemore and Braemar, down to -6C on Saturday night, and Dalwhinnie to -8C on Sunday night.
