Three people have been killed as hurricane-force winds from Storm Ophelia battered Ireland and the UK.
A woman in her mid-50s died when her car was struck by a falling tree as she was driving close to the village of Aglish in Waterford, Ireland. A female passenger in her 70s was also injured and taken to Waterford Regional Hospital for treatment.
A man in his 30s was killed in a chainsaw accident as he tried to remove a fallen tree in Cahir, Co Tipperary, while a recovery operation is underway in Ravensdale, Dundalk after a car he was in was struck by a tree at around 2.45pm killing a man.

The RNLI has warned people to stay away from the sea during the extreme weather.
Matt Crofts, lifesaving manager, said seas are “particularly dangerous and unpredictable, with large waves and swells being a major risk”.
“Stormy conditions may be tempting to watch but big waves can easily knock you off your feet,” he added.
“The sea is far more powerful than you think and your chances of survival are slim if you are dragged into the swell.
“Our volunteer lifeboat crews will always launch to rescue those in danger at sea, but to launch into conditions like these could also put their lives at risk.
“We understand why people want to experience extreme weather but it’s not worth risking your life, so we strongly urge people to respect the water and watch from a safe distance.”
Anyone who sees a person in trouble in the water should dial 999 and not try to attempt a rescue themselves, he said.
The storm is expected to move across Wales, northern England and Scotland into Tuesday.
Planes were grounded at a number of airports in the affected areas and passengers have been warned to check ahead.
Schools and colleges were closed in Northern Ireland, which is covered by an amber weather warning, meaning there is a “potential risk to life and property”, issued when forecasters believe people need to be prepared to change their plans and protect themselves from the impact of severe weather.
Flights and ferries have been cancelled in parts of Scotland.
Motorists on the M77 in western Scotland faced lengthy tailbacks as a lorry overturned in high winds at about 8.30am and blocked the southbound lane for more than a hour.
A yellow warning for high winds is in place for much of Wales, Scotland, north-east England, north-west England, south-west England and the West Midlands.
Parts of Scotland and Wales have been upgraded to amber.
Forecasters have warned of flying debris, such as tiles blown from roofs, as well as large waves around coastal districts with beach material being thrown on to coastal roads, sea fronts and properties.
“It will be gradually easing up into Scotland overnight and into Tuesday morning, it’s weakening as it goes,” Met weather forecaster Grahame Madge said.
“Parts of England, areas like the North West, are covered by a warning. The impacts will be felt in northern England into Tuesday.”
