Ferry and rail passengers have been warned of cancellations and delays as gusts of up to 65mph (105km/h) are forecast to batter the English and Welsh coasts at the weekend.
The Met Office issued a yellow weather warning for wind in parts of England and Wales from 6am on Saturday until 9pm the same day, and prolonged rain was forecast.
Boat crossings on the Irish Sea in the morning and the Channel in the afternoon were likely to be affected.
Parts of south Wales and south-west England could experience gusts of up to 50mph, which could reach up to 65mph in coastal areas, the weather service said.
A separate yellow weather warning for rain was issued for Northern Ireland for Saturday morning, from midnight to midday. The Met Office said this could cause flooding of train tracks and homes, power cuts and road closures.
Gusts of up to 35mph were also likely, reaching up to 50mph near areas of the eastern coast.
Flooding and train delays have affected parts of the UK over the last week. Between 25mm and 30mm of rain fell across parts of north-east England on Wednesday, while about 20mm fell in areas of London, the Met Office said.
About a square mile of Wembley, north-west London, was under 1 metre-deep flood water, with firefighters called to rescue a man from a van and evacuate 19 people.
The south coast was battered with 45mph-50mph winds, and 60mph gusts were recorded at the Needles on the Isle of Wight.
