Scotland, Northern Ireland and northeast England face travel disruption as an Atlantic storm sweeps towards the UK.
Strong winds and gale force gusts could affect many areas, with airports monitoring the likely impact on flights.
Gusts of up to 80 mph are forecast for later today and tomorrow in central, southern and northeastern Scotland, northern parts of Northern Ireland, and northeast England.
Elsewhere in the UK winds will still be strong on both Thursday and Friday, with gusts of up to 50-60mph, the Met Office said as it issued a severe weather warning.
Further severe weather warnings have been issued due to the risk of snow in western Scotland, Northern Ireland and northwest England on Friday and Saturday.
The Met Office has also issued a cold weather alert for northwest England and the West Midlands.
“We are working with Transport Scotland and the Highways Agency to ensure they have the latest information about which areas are likely to be most affected,” a statement said.
Forecaster Brent Walker said: “As the storm passes through and moves to the east of the UK on Friday north-westerly winds will bring in cold air which will see a drop in temperatures.
“This is expected to bring snow to northern and western parts of the UK, while other parts of the country will see a cold night on Friday with widespread temperatures of around -1 °C.”
