The Met Office has issued yellow warnings for wind covering all of Scotland and Northern Ireland, as well as large swathes of northern England and north Wales.
The warnings are valid at various times on Saturday afternoon, overnight and into Sunday.
Widespread gusts of 50-60mph (80-97km/h) are expected with the chance of 70mph (113km/h) gusts in exposed areas, especially around coasts.
Central and northern parts of Scotland could see winds peaking at 80-90mph (129-144km/h) with large waves bringing dangerous conditions along the coasts.
Winds as strong as these bring the threat of damage, power cuts and significant travel disruption.
Some roads and bridges could close, which could have major impacts on what is predicted to be the busiest Easter in four years for drivers.
Disruption to train and ferry services is also possible.
