Winds from Storm Floris, which have brought gusts of up to 82mph, have now peaked in almost all parts of the UK - here's the latest forecast
Warnings: An amber warning is still in force for large parts of Scotland, while a yellow warning covers Northern Ireland, northern areas of England and Wales, and other parts of Scotland
Power cuts: More than 43,000 homes in Scotland are without power, according to the energy provider - and some homes in Northern Ireland and Ireland are affected too
Roads: Most of Scotland's major bridges are closed to certain vehicles, while trees have been blown down in South Lanarkshire and on a house in Belfast
Trains and planes: Some rail operators have issued "do not travel" warnings, while dozens of flights to and from UK airports have been cancelled
"It felt like a trip to Thorpe Park," says our reporter on a turbulent flight, while this footage shows another plane struggling to land in Leeds
Damage and disruption as Storm Floris crashes into UK

The latest view from space shows the centre of Storm Floris is located to the south of Shetland.
Strongest winds at the moment are around the Moray Firth, gusting to about 80mph (129km/h).
But winds are expected to rapidly increase over the coming hours in Orkney as the storm continues to head eastwards.
Steven Topping tells Radio Scotland's Drivetime that at the caravan park where his family is staying in Sutherland, if you try to stand in the wind, you're almost blown over.
He describes the scene at the Parkdean Resorts Grannie's Heilan' Hame Holiday Park: "There's a lot of debris, a lot of chairs, a lot of tables have fallen over.
"We had a barbeque here yesterday - today is the total opposite."
He says they've had no electricity at the caravan park all afternoon.
"The caravan is now rocking much less," he adds on a more optimistic note.
Mike and Sue Carson are the last campers left at a site just outside Kilchoan, a village on the Ardnamurchan peninsula in Scotland.
Since about 04:00, Sue tells this live page they've had to hold their tent down, "literally doing shifts".
"We haven't been able to leave the tent without one of us being in here."
They say it feels like doing a good workout.
The worst part? "It's been the gusts," says Mike. "It does feel a bit like the tent is on top of a car on the motorway."
The couple say the wind started from the south east, blowing right up the Sound of Mull, but has now moved westward - so they're getting a brief break.

Measured in emissions per kilowatt hour of electricity, that meant a drop from 168 grammes at 21:00 last night to 46 grammes by mid-afternoon.
The wholesale price of power is set every half hour, and National Grid says it fell from £107 per megawatt hour at 21:00 last night to less than £6 by the end of this afternoon.
But at high wind speeds, wind turbines sometimes cut out.
Scottish Power says its turbines have a safety mechanism with sustained gusts above 56mph (90km/h) - though the company's preferred measure is 25 metres per second (56mph).
To avoid overheating the gearbox, it disengages at that high speed, but only for a few minutes.
Scottish Power has seen several automatic cut-outs today, but reports "no issues" with its turbines functioning normally in today's high winds.

Storm Floris will continue to move eastwards and bring the potential for disruption across Scotland, although many northern parts of the UK will also see the unseasonably strong winds continue.
The amber warning across Scotland is valid until 23:00 tonight, though we’re expecting the winds to peak across the north-east of Scotland in the early part of this evening with gusts of 70-80mph (113-129km/h) - perhaps even higher than that in exposed spots.
The Northern Isles will stay windy throughout the night, again with gusts possible of 70-80mph.
South Uist in Scotland still has the highest recorded wind speed, with a gust of 80mph - which is no change from earlier.

But Scotland's Justice Secretary Angela Constance warns the storm isn't over yet, and the amber warning remains in place until 23:00.
The minister, who's been at the heart of the Scottish government's response to Storm Floris today, tells Radio Scotland's Drivetime: "There has been significant disruption, particularly across the travel networks."
Constance says the same advice as earlier still applies:

Some train operators have issued "do not travel" warnings for today.
ScotRail says the storm is causing significant disruption - a 50mph (80km/h) speed restriction is in place on all of its routes.
East Coast Main Line services north of Newcastle are cancelled, and West Coast Main Line passengers are being advised not to travel north of Preston.
Roads
Most of Scotland's major bridges are closed to certain vehicles, with many closed entirely.
There have also been reports of fallen trees closing or partially blocking roads, particularly in Scotland.
Storm Floris has caused 68 departure flights to be cancelled from UK airports so far - that's about 2.2% of all scheduled departures, according to aviation analytics firm Cirium, external.
So far today, 66 arrivals into UK airports have also been cancelled - again, around 2.2% of all scheduled arrivals.
The worst affected airports are:
Image source, ReutersAs we head towards rush hour, here’s where things stand with Storm Floris making itself felt across the UK.
An amber wind warning is in place for much of Scotland until 23:00 BST, with gusts of up to 80mph (129km/h) recorded in the Outer Hebrides.
A yellow wind warning also covers northern England, Northern Ireland and parts of Wales and Scotland, lasting until 23:59.
Scotland’s travel network has taken the brunt of the disruption, with services north of Newcastle cancelled and passengers advised not to travel north of Preston by train.
Northern Powergrid is urging people to report power cuts, as fallen trees damage infrastructure.
Although Met Office weather warnings end tonight, there’s a warning that disruption could continue into tomorrow, with Scottish exam results delivery delayed in some areas.

Looking out from his caravan near Dornoch in Scotland, Steven tells the BBC the view might look nice - but he can barely stay upright when he goes outside in the wind.
"There is no electricity here at all for the last hour and we've no idea when it will come back on," he says.
Steven is at the caravan park with his wife Caroline, son Lewis and daughter Amy.
He says they've been using a gas cooker to boil water for tea.
Scottish and Southern Electricity Networks (SSEN) says it has restored power to about 5,500 customers since Monday morning, but another 22,500 across the north of Scotland are still without electricity.
Andy Smith, SSEN director of customer operations for the north of Scotland, describes Storm Floris as "the strongest summer storm we’ve seen in a very long time".
Aberdeenshire, Moray and the Highlands have been especially badly hit, according to SSEN, and severe winds could affect more customers later on.
SSEN also says some people may be without power overnight.
Royal Mail says there will be delays to the delivery of Scottish Qualifications Authority (SQA) results in several parts of Scotland, due to disruption caused by Storm Floris.
Deliveries to the Outer Hebrides, Orkney and Shetland will be particularly affected.
There may also be further localised delays at short notice.
If you’ve signed up for MySQA, external in the past, you will still receive your results by text and/or email tomorrow morning around 08:00 tomorrow, across all of Scotland including those affected by the delay.
Anyone waiting for their results is advised to contact their school or college first, as they should be able to help.
Alternatively, learners can submit an enquiry through the SQA website, external. Queries will be responded to after 12:00 on Tuesday 5 August.

Live reporter writing from Luton Airport
For the second time today, I am standing at Luton Airport Parkway station.
It is miserable now - it wasn't at 07:00 this morning.
The weather is quite fitting to my mood. My flight to Inverness, delayed two hours, eventually took off.
After an hour in the sky the captain told the crew to prepare for landing.
This was followed by sudden turbulence - and a quick aborted landing, with a sharp pull up into the air.
We were almost vertical - and it felt like a trip to Thorpe Park.
My parents, who I was due to visit, saw the whole thing while I learned they were taking us back to Luton.
So here I am again, with all other options fully booked.
I will laugh one day!
As Storm Floris rolls across the UK, Scotland's travelling network is bearing the brunt of the disruption.
As we've been reporting, all East Coast Main Line services north of Newcastle are cancelled, and West Coast Main Line passengers are being advised not to travel north of Preston.
Now, a sign at Manchester Piccadilly station has been spotted advising people not to head to Scotland for the rest of the day, with amber wind warnings set to last until 23:00 BST.

Despite the winds, their large tent is holding up pretty well.
They tried to get an Airbnb for tonight, but there wasn’t any availability.
The plan is to spend today in a soft play centre - where it should be a bit drier.

Image source, Jessica Lawrence/BBCNorthern Ireland has been hit by strong winds of up to 63mph (101 km/h).
Workmen in hi-vis jackets are battling sudden strong gusts to clear the remains of a large tree that has fallen into a house in north Belfast.
The quiet residential area has been closed off since this morning, as workers with small cranes and chainsaws try to clear up.
A neighbour said he heard a loud bang just after 09:00 BST, thinking it was a bin. However, he soon realised it was something more serious and another neighbour alerted emergency services.
The owners of the home are an elderly couple in their 80s, who are shaken up after this morning's incident.
The fire service says the couple were briefly relocated to a safe location while the damage to their home was assessed.
