The first named storm this winter is set to hit Scotland with the Met Office warning of potential danger to life and widespread transport disruption.
Storm Arwen has caused an amber weather warning to be issued across the east of the country, with gusts of 80mph forecast.
It is set to sweep across Scotland at around 3pm on Friday afternoon, but a yellow weather warning has also been issued across the whole country with power cuts, road closures, and damage to trees and structures all possible.
Much of the Highlands has been warned to expect snow and high winds, with a chance that some could be stranded if caught up in blizzards.
The Met Office said it is possible that some communities might become cut off in the latter half of the day, with every school in Orkney closing for the day at 1pm.
BEAR Scotland, which looks after the trunk roads in the north-west, north-east and south-east of Scotland, said it is primed to tackle whatever weather conditions Storm Arwen brings.
Restrictions may be required on bridges such as Skye Bridge, Kessock Bridge, Dornoch Bridge, Cromarty Bridge, Friarton Bridge and the Forth Road Bridge.
Eddie Ross, BEAR Scotland’s operating company representative for the north-west, said: “We are fully prepped and are closely monitoring conditions and will act quickly when required.
“We remind members of the public to check before travelling. Traffic Scotland is a great source of the latest journey information and advice. Drivers of high sided and wind-susceptible vehicles such as caravans and trailers should take particular care and check for restrictions.”
A yellow weather warning for wind is in place across most of the country from 9am on Friday until 6pm on Saturday.
An amber warning for Storm Arwen is in place across the east coast from 3pm on Friday until 9am on Saturday.
A yellow warning for snow is in place across much of the Highlands from 2pm on Friday until midnight.
Transport minister Graeme Dey said: “The first storm of the winter period, Storm Arwen, is set to impact Scotland tomorrow and Saturday.
“The whole country is going to see blustery conditions, but the Met Office is telling us that eastern parts of Scotland in particular are going to see some difficult weather.”
Superintendent Simon Bradshaw, Roads Policing, said: “We are asking motorists to be prepared for the potential for widespread strong winds and the risk of snow following the amber and yellow weather warnings from the Met Office.
“You should allow extra time for your journey, ensure your vehicle is sufficiently fuelled and drive to the road conditions. Consider taking some warm clothes, food and water within your vehicle, in case of delays and ensure your mobile phone is fully charged.
“I would urge motorists to check the Met Office and Traffic Scotland websites and social media before setting out on their journey, particularly in those areas most affected by the predicted adverse weather.”
