Two people have died after Storm Ali swept across parts of the UK and Ireland, bringing winds of up to 100mph.

A woman died after the caravan she was in was blown off a cliff in the Irish Republic, while in Northern Ireland a man was killed by a falling tree.

Others have been injured, including a woman who was badly hurt when a tree fell on a car in Cheshire.

Thousands of homes are without power, lorries have overturned and a cruise ship broke free from its moorings.

A yellow warning, meaning "be aware", is in place for Northern Ireland, Scotland and northern England until 22:00 BST.

Ali is the UK's first named storm of the season.

A man in his 20s was killed and another in his 40s was injured, after a tree fell on them at the gates of Slieve Gullion Forest Park, near Newry, County Armagh.

The men were working on behalf of Northern Ireland Water.

It is understood the woman who was killed in County Galway was a tourist in her 50s who had been staying at a campsite in Claddaghduff.

Cheshire Police said a woman in Crewe was taken to hospital with serious injuries after a tree fell on a car on the A49.

In Scotland efforts will continue throughout the night to restore power supplies and clear debris from roads and rail.

One person was injured after being blown over by high winds outside the new V&A Dundee museum, which was later closed.

Five hundred cruise passengers and crew were stranded in Greenock after severe weather broke their ship's mooring lines. Tugs were called in to assist the Nautica.

A 102mph gust was recorded on the Tay Road Bridge between Dundee and Fife at 15:00.

Belfast City Council said it had closed all its parks, pitches and playgrounds, while Derry City and Strabane District Council closed all its parks and cemeteries "until further notice".

BBC Weather said on Wednesday evening that the wind had dropped - although the yellow warning remains in force across the whole of Scotland, and parts of North Wales and northern England.

Those areas are likely to experience gusts of up to 60 mph but could face similar levels of danger and damage.

BBC Weather said the storm could have a greater impact because of the time of year.

It said most trees were still in full leaf and were "acting like sails", making it more likely they could be pulled over and cause travel problems.
