A storm is forecast to hit parts of the UK with strong winds and heavy rain as multiple amber warnings come into force.
Storm Isha - the ninth storm since September - will bring winds of up to 80mph, according to the Met Office.
Forecasters also warned of large waves and debris being blown inland in coastal areas, posing a potential risk to life and damage to buildings.
The amber warnings could lead to power cuts and increased congestion as roads and bridges are likely to be shut, while rail and bus services could face delays and cancellations.
East Midlands Railway said it expected "significant disruption" on Sunday and Monday, while Police Scotland advised people to avoid unnecessary travel.
Yellow warnings for rain and wind are in place for the rest of the country on Sunday, with floods likely.
The heaviest rain is expected on Sunday, with 30mm to 50mm in many places and 80mm to 100mm in hillier areas.
Warmer weather will accompany the adverse conditions after a week of snow and sub-zero temperatures.
Met Office meteorologist Alex Burkill said weekend temperatures were "going to be much higher than they have been" with highs of 12C to 13C (53.6F to 55.4F).
However, he said the strong winds, rain and clouds could overshadow the milder weather so it might not "feel quite so warm".
He added: "Temperatures will be on the mild side, lifting as we go through this weekend and staying mild through much of next week.
"There may be some chillier spells but I think that any frost is likely to be isolated if we see any at all."
