Thousands of homes remain without power, mainly in the north of Scotland, though there are also power cuts in the north of England and parts of Wales, three days after gales gusting up to 113mph first struck Britain.
Although the ferocity of the wind has eased, engineers have been struggling to restore electricity in conditions described as treacherous and worsening. Many transport links were affected on Sunday, including trains running north of Glasgow and Edinburgh to Inverness, and ferries to the Hebrides and other islands. With forecasters predicting more snow and gales, there are warnings that disruption will continue and perhaps worsen in the next few days.
A Met Office “be aware” warning of strong winds, severe gales in places and heavy rain has been issued for all of Scotland and most of northern England for Monday, with warnings of localised flooding where rain falls on saturated ground or melting snow.

Scotrail warned of cancellations and delays, with flooding or fallen trees and other debris brought down by the storms blocking many lines.
In parts of Scotland the Red Cross has been delivering hot food and drinks, and gas heaters, to some households.
Two walkers who were stranded by the snow and took refuge overnight in a bothy near Loch Etchachan were rescued by the Braemar mountain rescue team on Sunday morning.

In Sussex, the body of a 24-year-old Brighton man was recovered from the sea, but the friend he attempted to rescue in the small hours of Saturday is still missing, presumed drowned.
Freddie Reynolds, whose body was recovered four miles away at Saltdean, went in near the Palace Pier in Brighton to help his friend, Dan Nicholls, who had been knocked off his feet by a wave after walking along the water’s edge for a dare.
Although the alarm was raised immediately, conditions were described by the coastguard as awful.
Reynolds’s family described him as a loyal and brilliant friend. The search for Nicholls’s body continues.
