The Met Office has warned of a possible “danger to life” – with 80mph winds set to hit parts of the UK.
A yellow warning for wind is in place for much of the country from 10am on Wednesday to 7am on Thursday.
It spans from the southwest of England, up to Scotland and across to Northern Ireland.
“Injuries and danger to life from flying debris” are possible, the Met Office said, as it warned of “large waves and beach material being thrown on to sea fronts, coastal roads and properties”.
It said the spell of “significantly disruptive” strong winds could cause damage to buildings, power cuts and travel disruption.

Mark Sidaway, deputy chief meteorologist at the Met Office, said: “A deep area of low pressure is expected to approach southwest Ireland early on Wednesday, and track across northern parts of the UK before clearing early Thursday.
“There is some uncertainty on the precise track and strength of this weather system, however the most likely outcome at present is for a wide swathe of 50 to 60mph gusts affecting inland areas.”
He added: “Some Irish Sea coasts could see gusts of 65 to 75mph, with a small chance of 80mph gusts on the most exposed coasts and headlands.”

It follows a period of heavy rain as the remnants of two hurricanes – Lee and Nigel – swept across the country.
The weather couldn’t have been more different earlier in the month though, when – for the first time ever in September – a heatwave saw temperatures in the UK top 30C for seven days in a row.
Saturday marked the autumn equinox, when summer officially ends and autumn begins.
