The Met Office is warning of winds of up to 80mph at the weekend - as a separate rain alert remains in force until midnight today.
The forecaster said a "windy period is expected across the whole of the UK on Sunday and into Monday".
Scotland and Northern Ireland, as well as parts of North Wales and Cumbria, are expected to see the worst conditions and are under a yellow warning beginning at 3am on Sunday.
Gusts of 50-70mph (80-112kmh) are expected in the morning, but later in the day could hit 80mph (128kmh) in exposed areas such as western Scotland.
The Met Office said there is a small chance buildings could be damaged and waves and flying debris could cause injuries and pose a "danger to life".
The warning ends at midday on Monday.
