Winds could hit 70mph (113km/h) across parts of north Wales overnight into Saturday, forecasters have warned.
The Met Office has issued a revised yellow alert for high winds covering the region from 03:00 GMT until 18:00.
Residents across Conwy, Denbighshire, Flintshire, Gwynedd and Anglesey have been told to expect gusts of 50 to 60mph – but even more on exposed high ground.
The gales could lead to some travel disruption in those areas affected.
Forecasters have also highlighted a “slight risk” of damage to buildings, while the public has been warned to be aware of spray and large waves along the coast.
