The Met Office has issued a yellow weather warning for strong winds as gusts of 60mph could bring “dangerous conditions” to parts of the UK.
Areas in northern Wales, northern England and southern Scotland can expect the extreme conditions on Thursday from 1am until 9am.
There is already another yellow warning for heavy rain in western Scotland, which came into force on Wednesday morning and will run until 8am on Thursday.
Forecasters said some places, including Glasgow, could see 75-100mm (3-4in) of rain in 24 hours, with “as much as 150mm (6in)” on the hills.
This could cause difficult driving conditions, travel disruption and flooding in places.

Thursday’s high winds will further complicate the conditions with the Met Office warning “gusts will be strong enough to blow over a few trees, given that they are currently in full leaf”.
In an update on its website, the Met Office added: “A spell of very strong southwesterly winds will occur during the early hours of Thursday, easing from the west during the morning.
“Gusts of 50mph are likely fairly widely with some gusts of 60mph in exposed locations, including roads and bridges in north Wales, as well as roads passing over high ground in northern England and southern Scotland.”
People on coastlines were urged to “stay safe” and to be “aware of large waves” while forecasters said the winds could bring travel disruption and power cuts.
The Met Office said remnants of Hurricane Ernesto, which ripped through the North Atlantic last week, will play a role in the rain and windy weather.

Chief meteorologist at the Met Office Jason Kelly said the rain in Scotland will be “slow moving” before the winds bring worsening conditions.
“Gusty winds will accompany the rain, with 50-60mph possible near Irish Sea coasts and the west of Scotland,” he said.
“Coupled with spring tides, this could lead to some dangerous coastal conditions before winds gradually ease later on Thursday.”
