Damage and disruption as Storm Floris crashes into UK
As we've been reporting, Storm Floris is bringing unseasonably strong winds to Scotland.
And, one tree in a reader's South Lanarkshire home has already fallen victim to the gales this morning - take a look.

Met Office forecaster Peter Sloss tells Radio Scotland's Lunchtime Live Storm Floris is a very unusual event in August.
"I think we've had five named storms, since the naming process started a number of years ago in August.
"This one really is the most powerful of these storms that we've seen."
The forecaster says we are "sort of in uncharted territory at the moment".
For example Tiree saw a gust of 75mph which is a record for this month, he adds.
Scotland is set to be worst hit by Storm Floris, but parts of England and Wales are also facing high winds and wet weather.

Strong winds and travel disruption have dashed the hopes of comedian Casey Railton's improvised comedy group, the Spontaneous Wrecks.
The aptly-named group say their only spot at Edinburgh Fringe is now "completely cancelled" after several of their members were unable to catch trains.
Casey says: "We started to see train cancellations pop up yesterday, and now that the amber warning is in effect, I'm stuck at home."
The group had debated performing with just the members already in Edinburgh, but "given the weather conditions and the need to flyer for an hour beforehand, we decided to cancel".
As we reported earlier, several events in the city have already fallen foul of the weather.

Network Rail Scotland say its engineers are dealing with fallen trees on the tracks in the west of the country.
The Glasgow Queen Street-Cumbernauld route has been partially blocked by a fallen tree, which has reportedly caused minor damage to overhead wires.
At Giffnock, on the other side of Glasgow, a tree is also on the line and has damaged fencing around the track.
There are also reports of a fallen tree blocking the line at Summerston, in the north west of the city.

Scottish and Southern Electricity Networks is reporting scattered power outages across a large part of Scotland.
Some outages have been reported in mainland Orkney and Shetland.
Northern Ireland Electricity Networks is also reporting power cuts across all counties. The utility company estimates reconnection will be around lunch time.
Multiple power outages are also being reported in the Republic of Ireland, according to ESB Networks.

View from the Highlands as Storm Floris strikes
I'm in the highland town of Kingussie where the wind is really starting to pick up.
It’s due to be hit hardest later this afternoon.
The trees are swaying, and many of the road signs are bending back and forward.
It's not ideal for the holidaymakers who are visiting this beauty spot in the Cairngorms National Park.
Image source, PA MediaThe RAC says Storm Floris will result in "major disruption" in the north and west of the UK while roads are much busier with holiday traffic.
Those on the roads have been urged to drive at lower speeds, leave extra stopping distance and delay journeys in the worst-hit areas.
"Extra luggage and passengers, combined with wet roads, increase stopping distances as the brakes take have to cope with the extra weight," Alice Simpson tells us.
"It's best to drive slowly and keep a firm grip on the steering wheel so you can cope with being buffeted by the wind. Drivers should also be very wary of high-sided vehicles, which are more likely to be affected by strong winds, and watch out for debris in the roads."

BBC Scotland news reporting from Peterhead
The worst of the weather is still to hit Peterhead in the north-east of Scotland.

In both cases, passengers are being asked to contact their airline directly for updates on the status of their flight.
Image source, Getty ImagesIt's not just humans hunkering down for the day, as we're hearing that Edinburgh Zoo has closed partially for the public.
In a post shared on X, Edinburgh Zoo says: "Due to strong winds from Storm Floris the top of the zoo (from the path to lions and above) will be closed today."
A scan of the map suggests that the lions, tigers, giraffes, zebras and anteaters may be out of action today.
The rest of the zoo is still open to the public. In a statement, Edinburgh Zoo says that all pre-booked ticket holders have been contacted by email.

Heart of Midlothian host Scottish Cup holders Aberdeen at a sold-out Tynecastle Stadium at 20:00 BST.
Authorities say as things stand the Scottish Premiership match is still set to go ahead despite the high winds across Scotland.
"Please take care when making your way to and from the capital and should anything change, we will endeavour to update as soon as possible," Aberdeen Football Club say in a social media post.

Most of Scotland's major road bridges have been closed to certain vehicles.
The Clackmannanshire Bridge and Skye Bridge are closed to high-sided vehicles, while double decker buses are currently suspended from the Tay Road Bridge in Dundee.
Meanwhile the Forth Road Bridge is also closed to double deckers, as well as motorcycles and pedestrians.
The Tyne Bridge in East Lothian is closed in both directions. In an update shared on X, Traffic Scotland said that all traffic is to divert onto the A199 as an alternative route.
However, the Queensferry Crossing between Edinburgh and Fife is open, as is the Friarton Bridge in Perth and the Kincardine Bridge, between Falkirk and Fife.
A yellow wind warning covering the Northern Isles of Scotland has been extended until 08:00 BST on Tuesday.
This means that there may be some damage to buildings in this region, with injuries and a danger to life from debris also possible.
Residents should also expect power cuts and delays to travel with interruptions to infrastructure possible.
