What to expect as Storm Éowyn hits UK
The attic wall of a house in south Belfast has collapsed during the storm.
The debris is lying across the road on the Ormeau Embankment, a few miles outside of the city centre. The home is next to the River Lagan, which runs through Belfast.
Earlier, we reported that Storm Éowyn has already broken records for gusts in the Republic of Ireland.
That was after a wind gust of 114mph (183kmh) was recorded at Mace Head in Galway.
With a red wind warning now in effect in Scotland.
Sustained winds of up to 85 mph (137 km/h) have been recorded in the Republic of Ireland. Wind speeds are measured over a period of 10 minutes, while gusts are recorded in three-second bursts.
Here's a look at the damage high winds can cause - our graphic uses the Saffir-Simpson scale, which measures damage based on sustained wind speeds.

That’s the strongest gust since 93mph (150km/h) was recorded at Ballykelly in County Derry on Boxing Day in 1998.
It’s also the strongest gust of wind on record for the weather station in Killowen.

A few minutes before the red alert came into effect at 10:00 GMT, Paisley Road West in Govan was close to deserted.
In a parade of 14 shops, only three were open - and one shop assistant told me he was hoping to be able to go home.
In the neighbourhood, the shops that were open were takeaways, small food shops and a chemist.
A few cars were on the road - and the first debris and branches from the storm are beginning to litter the street.

"Travelling in this weather is dangerous to all road users and responders," it says.
The A75 is the main route across Dumfries and Galloway, running from Gretna to Stranraer.

A Three spokesperson says: "Following an issue affecting voice calls yesterday, services have returned to normal overnight.
"We continue to monitor and review all services throughout today to ensure full stability. However, today we expect to see an additional impact on our service due to Storm Éowyn in some areas."
The spokesperson says extra engineering resources have been deployed to deal with any disruption caused by the storm.
The company has also launched an investigation into the "small number" of reports of 999 call failures.

Irish Water is urging people in Ireland to conserve water, as they could face supply issues due to the storm.
It says that around 155,000 premises are at risk, but the majority should still have water due to reservoirs.
But the service says significant disruption is expected, and crews will begin to restore supply when it's safe.
In a statement, it adds: "In areas where supply has been disrupted, most properties should have adequate storage in their attic tanks for hygiene purposes for at least 24 hours.
"However customers are urged to conserve water where possible in order to protect supply while the outages are resolved."

It’s possible the west coast of Ireland has been hit by a "sting jet".
This can occur in powerful storms where strong winds higher in the atmosphere are forced to the ground, resulting in wind speeds in excess of 100mph (160km/h).
We can normally detect a sting jet on a satellite image as the hook – or "sting in the tail" – to the southern side of the storm.
They normally occur as a storm system reaches its most powerful stage and can last for up to four hours, bringing the most damaging winds.
During the infamous great storm of 1987 in southern England, it is thought a sting jet was responsible for the strongest gusts.
But, in the late 1980s, little was known about the phenomenon and we didn’t have high resolution satellites to help in identifying them.
The second red warning issued by the Met Office has taken effect in Scotland. The alert, which began at 10:00 GMT, covers the Central Belt - which includes the major cities of Glasgow and Edinburgh.
Hundreds of schools are closed, more than 1,000 properties are without power and there is no rail travel at all in the country.
A red warning indicates a danger to life, and the Scottish government is meeting with emergency services and key agencies like health and transport providers to co-ordinate the response.
People are advised by Police Scotland to stay at home.
The warning will be in place until 17:00 GMT.

BBC Scotland political correspondent
Scotland's deputy first minister is urging people to follow Police Scotland advice not to travel in or to the red weather warning area as Storm Éowyn hits.
Kate Forbes told the BBC that if people stay at home they reduce the risk to themselves.
Over the course of today, the Scottish government's "resilience room" will host further meetings to understand the scale of the impact and what might come next.
Government ministers will meet with emergency services and key agencies like health and transport providers to co-ordinate the response.
She said the red weather warning is particularly severe and it's rare for the Met Office to issue such alerts, adding that utility companies have already been in touch with vulnerable customers to encourage them to prepare.
The deputy first minister also welcomed the closure of main shopping stores, saying businesses have a responsibility for the safety of their workforce.
The warnings in place across the UK are mostly for wind, but there is still some threat of rain - and with that can come flooding.

There is no similar flood tracking system in Northern Ireland, but you can report flooding by phoning 0300 2000 100.
As the day begins, we're starting to see images showing the force of the winds that are ripping across the UK and the Republic of Ireland.
Trees have been knocked down, a telephone pole has been broken in half, and waves are cresting as the storm makes itself known.

Storm Éowyn is already breaking records in Ireland.
A wind gust provisionally registered at 114mph (183kmh) at Mace Head in County Galway is the strongest gust ever recorded by the national weather agency Met Éireann.
I am 70 miles north of that point – at Westport in County Mayo.
The storm made landfall here on the Atlantic Coast shortly after midnight - and the gales are truly ferocious, with the peak yet to come.
There are hardly any vehicles on the road, with the vast majority of people seemingly heeding the advice of authorities to stay at home if at all possible.
A red warning, indicating danger to life, is now covering the whole of both Northern Ireland and the Republic of Ireland – the first time this has happened.
In the Republic, 560,000 homes and business are currently without power.
