While it will be the strength of the wind linked to Storm Floris that has the biggest impact, a spell of rain is also sweeping across the country.
Between 25 and 50mm (1-2in) of rain has fallen in some parts of western Scotland since midnight, although the band of rain will turn lighter as it heads head across England and Wales.
Above, you can see how the rain radar looked during rush hour.

ScotRail has issued a call for people to secure their garden furniture, trampolines and tents "so that they don't blow onto the tracks and interfere with lineside equipment".
The Met Office warns that "flying debris could lead to injuries or danger to life" in parts of north-west Scotland where an amber weather warning is due to come into effect at 10:00BST.
Stay with us as we continue to monitor travel disruption caused by Storm Floris.

The centre of the storm, with the strongest winds wrapped around it, is still to the west of northern Scotland right now.
Expect winds to start increasing as it closes in over the next hour or so.

Surprisingly not, but the forecast strength of Floris is.
It may be the last of the three summer months, but the Atlantic storm season is kicking into gear and we can sometimes see a lively jet stream fire up.
There have been a number of notable named storms over the last few years as a result.
Only last year, Storm Lilian battered parts of England and Wales at the end of the month, ripping up tents and forcing the closure of three stages at the Leeds Festival, and causing the delay of Creamfields.
In 2023, there were two named storms that made their mark, Antoni (also on the 4th) and Betty on the 18th. Antoni brought the most impacts, and mainly to England and Wales.
2020 brought "two of the most notable August storms in 50 years" to the UK, Ellen and Francis.
Large waves battered coasts and peak wind speed of 79mph in Gwynedd with Ellen, 81mph in Isle of Wight from Francis.
Floris may well exceed both these speeds.

There are speed restrictions across the whole network because of the amber weather warning, he says.
"That means we will operate significantly fewer services than we normally would, and across a number of routes there will be no services at all throughout the course of the entire day."
He says the advice to passengers is to take a look at the ScotRail website or the app, to see exactly what’s running and when.

An amber warning is in place from 10:00 BST across much of Scotland. It is the second highest level of alert issued by the Met Office.
It means that a particular weather event is not only likely to happen but that it will have a high impact too.
It's likely that plans will be disrupted by the weather with the possibility of travel delays and cancellations, there could be power cuts and there is a potential risk to life and property.
Within the amber warning area, Storm Floris is likely to lead to road and bridge closures and travel delays from the strength of the wind. There will be large waves in coastal areas with beach material being thrown onto seafronts. There could be damage to trees and buildings such as tiles blown from roofs. Flying debris could lead to injuries or danger to life.
The wind will also be accompanied by heavy rain.
With winds of up to 70mph in coastal areas forecast for today, we want to hear how you have been impacted.
We also want to see your pictures of the stormy weather from the across the UK.

The Met Office started naming storms in 2015.
Areas of low pressure are generally only named when it is anticipated that they will bring significant impacts or disruption to daily life. However, due to the naming process, some named storms may be more notable than others.
Across Europe, various national weather services group together to name areas of low pressure that are forecast to have impacts in their part of the continent.
For us, the Met Office collaborates with the Irish and Dutch weather services. This means that some named storms may have their most significant impacts in Ireland or the Netherlands than here in the UK. Presenters take this into account when delivering the forecast.
Naming storms has been shown to improve awareness of severe weather and helps forecasters to provide easy to follow and consistent messaging.
The list of storm names is announced on 1 September each year and runs in alphabetical order, starting this season with Ashley, followed by Bert, then Conall, Darragh, Éowyn and now Floris.

The organisers of Fringe By The Sea in North Berwick, East Lothian, have announced the cancellation of today's events due to Storm Floris.
They say the festival, which runs more than 250 shows from 1 and 10 August, will reopen on Tuesday at 10:00 BST.
Edinburgh City Council has also announced that Princes Street Gardens will be closed on Monday and Tuesday as a precaution, leading to the cancellation of some Edinburgh International Festival events including Monday's ceilidh sessions.
Meanwhile Edinburgh Fringe Festival are monitoring the impacts of the "evolving storm", they say: "Should a show be cancelled our customer services team will be in touch with customers who have purchased tickets... we will update advice and guidance throughout the day tomorrow."

On Thursday morning a band of intense showers and thunderstorms crossed to the south of the Great Lakes in the US. By Friday storms raged across New York and New Jersey causing widespread flooding and disruption.
These amalgamated into a developing area of low pressure over the western Atlantic which, over the weekend, has been picked up by a jet stream approaching 200mph in speed and transported towards our shores.
The crucial bit for us is that the area of low pressure is now interacting with part of the jet stream which helps to deepen it rapidly, causing winds wrapped around the low to increase dramatically.
And the timing of that is such that the strongest winds will be as the low crosses Scotland today.
It's a gloomy start for many people in northern parts of the UK this morning - at least that's the picture we're getting from our Weather Watchers:

"LNER are advising that customers do not travel north of Newcastle until the end of the day. All stations north of Newcastle will not be served."
The train operator say that alternative travel options will be extremely limited due to expected road closures - and point out that other rail networks will also be affected.
Scotrail have put a 50mph speed restriction in place as they warn Storm Floris will bring disruption.
They say "significantly fewer" services will run, some lines will be closed all day, and some routes will stop running around lunch time. Customers are advised to check the ScotRail app and website for updates.
Avanti West Coast has advised customers not to travel north of Preston today as they say their routes from England into Scotland are expected to be heavily affected by Storm Floris.
Affected destinations north of Preston on their route include Lancaster, Oxenholme, Penrith, Carlisle, Lockerbie, Motherwell, Haymarket, Glasgow Central and Edinburgh.
Speaking in a rainy Gourock, Inverclyde, the BBC's Jamie McIvor says it's the severe wind later which is going to cause the major disruption.

In a statement, Edinburgh Tattoo said "we understand this will be disappointing, but the safety of our audience, performers and staff is our top priority".
They say that all tickets for the performance this evening will be automatically cancelled and refunded, adding: "We currently expect to go ahead as usual on Tuesday 5 August, but we will continue to monitor the weather and provide any further updates on our website and social channels."

The peak winds are likely to be across the Western Isles, Skye, Ross and Cromarty between 10:00 BST and 13:00.
Winds gusts in these areas could widely hit 70-80mph, perhaps even touching 90-100mph for a time.
Between 12:00 and 15:00 the strongest winds will have transferred to the north-east of the country, with areas of Caithness and those bordering the Beauly and Moray Firths most likely to see winds get close to, or exceed 80mph or 90mph.

The strongest winds will be across the Western Isles and the north of mainland Scotland, but disruptive and possibly damaging gusts of 50-70mph could be experienced across a large part of Scotland, from the Central Belt northwards.
All these areas are covered by a Met Office amber warning for wind.
However, wind gusts could still have impacts across the far south of Scotland, Northern Ireland, Isle of Man, northern England and north-west Wales - 40-50mph gusts can be expected widely, but possibly as high as 70mph on some coasts, bridges and hills.
For the rest of England and Wales, while generally blustery conditions and a spell of rain can be expected, the storm is not expected to have significant impacts.
