The Met Office has issued the warning for the weekend, with “strong winds” expected throughout today, Saturday, until 9pm tomorrow.
The weather service says delays to road, rail, air and ferry transport are “likely”. Bus routes and train services are also predicted to be affected, with “some journeys taking longer”.
Winds of over 50mph are expected in Bolton, with a “small chance” that they could reach 70mph elsewhere.
A Met Office spokesperson said: “Strong westerly winds are expected to develop through the course of Saturday, with gusts of 50-60 mph developing quite widely across this region, and a small chance of gusts reaching 70 mph around some coasts and high ground areas.
“This has the potential to cause delays to public transport and some disruption to the road network, which may have a greater than usual impact given the busier pre-Christmas weekend travel.
“Dangerous coastal conditions can be expected too, with large waves an additional hazard.
“Strong and gusty northwesterly winds are expected to develop on Sunday. Gusts of 50-60 mph are expected quite widely, and around some exposed coasts and hills of gusts 70 mph are possible, especially in the north and west. In addition, squally showers are likely with some hail and thunder possible in places.”
