Britain is set to face heavy wind, rain and possible snow as Storm Clodagh crashes into the coastline from the Atlantic.
The Met Office has issued a yellow warning of severe weather for most parts of the United Kingdom, also urging caution over ice and treacherous driving conditions.
Gusts of up to 70mph are expected to hit the western coast, with winds of 60mph forecast in inland areas in northern England.
The Environment Agency also issued a number of flood warnings for much of England and Wales, particularly in the north west and south west, with predictions of heavy rain into afternoon.
A spokesman for the Met Office said: "Although rainfall accumulations are not expected to be particularly large, rivers remain high from previous rainfall and are expected to respond, leading to the risk of flooding.
"The strongest winds are expected to reach Northern Ireland around dawn on Sunday, and most areas by the end of the morning, before gradually subsiding from the west during the afternoon and evening."
Up to 15cm of snow is also expected in some areas of Scotland, with the possibility of some snowfall in northern England.
Some areas have been forced into suspending their festive plans in light of the bad weather, with Bognor Regis, Portsmouth and parts of Ayrshire are all affected.
