Forecasters have warned the UK should brace for more cold weather, ice and snow over the weekend, following Storm Goretti.
Saturday will bring sunnier and drier conditions than recent days, but this will give way to rain and some snow on Sunday, the Met Office said.
Yellow alerts for snow and ice have been issued for most of the country, ahead of a blast of cold air moving in overnight on Friday into Saturday.
Train services remain disrupted with Transport for Wales, West Midlands, Great Western and CrossCountry all reporting various disruptions and alterations.
On Friday, Storm Goretti brought heavy rain, snow and strong winds to much of the UK. The Met Office said a low of -12.3C (10F) was recorded in Braemar.
Power was also disrupted to tens of thousands of homes.
Around 28,000 properties remained without electricity in the South West at 6am on Saturday, according to the National Grid, along with about 1,700 in the West Midlands and 150 in the East Midlands.
Melting snow and rain will increase the risk of flooding in the coming days, forecasters warned.
Trees were brought down under gale force winds and some flights were cancelled because of the storm.
Footage showed a passenger plane swaying in strong winds as it came into land at Heathrow Airport.
"Storm Goretti slopes away eastward tonight leaving a much quieter picture for Saturday," Sky News Weather presenter Jo Wheeler said on Friday.
"However, the cold air returns with a severe frost expected tonight along with icy stretches on untreated roads and pavements."
The Met Office issued yellow alerts for snow and ice across most of Scotland and parts of England's northeast until 3pm on Saturday.

In the early hours of Sunday, a band of rain will move in from the west, which will create a widespread risk of snow when it hits cold air, the Met Office predicted.
Snow is especially likely in Scotland, with areas of higher ground predicted to see 10 to 20cm (4 to 8in) of snow, and lighter falls in other areas.
A yellow warning for snow and ice is in force from Sunday between 2am and 3pm, which covers a large part of northern England and virtually all of Scotland.
"Cloud gathers Saturday evening with rain moving in from the Atlantic," Wheeler said.
"Meeting the cold air, there's the potential for some short-lived disruptive snow.
"Mild air takes over after that with conditions less dramatic next week."
Temperatures will remain low across much of the country on Saturday, between 2 to 3C (35 to 37F), and will rise to 10C (50F) in some parts of the west and Northern Ireland on Sunday, creating a risk of localised flooding early next week.
