A "vigorous" autumn storm will bring severe gales of up to 75mph to England and Wales this weekend, forecasters have warned.
The Met Office says Wales, the Midlands and northern and eastern counties of England are most likely to be hit by the "potentially damaging" winds.
Scotland and the Midlands are also being warned to expect flooding.
The worst of the weather is predicted to hit England and Wales at midnight on Friday and continue into Saturday.
The brewing storm has been described by the Met Office as "a developing, severe weather situation".
But its precise path remains uncertain, say forecasters. "Although the very strong winds are expected to be the main concern, the storm will also bring heavy rain and an increased threat of flooding," the Met Office said in a statement.
The Coastguard Agency has also issued a severe weather warning to mariners all around the UK.
It said there were "extremely high winds forecast for the next few days" and said the outlook from Friday suggested "gale force eight to storm 10, perhaps even violent storm 11 later - storm 11 is one force less than a hurricane."
Coastguards also warned against wave watching from promenades or piers because of the increased risk of being swept into the water.
People are being advised to watch weather forecasts and to ensure they plan well for any weekend activities. The warnings have come after Britain enjoyed the warmest extended summer period on record.
