AMID a red weather warning for wind, transport agencies have confirmed the high wind limits with would force bridges across Scotland to close.
It comes as forecasters warn gusts of up to 100mph could result in flying debris and pose a danger to life, and people are urged stay indoors.
Police said no road users should travel in the red weather warning area on Friday at the peak of Storm Eowyn.
The Transport Scotland Resilience Room and the Multi-Agency Response Team has said it is closely monitoring the conditions, with Traffic Scotland providing regular updates via social media, website and radio broadcasts.
The Scottish Government Resilience Room (SGORR) will also be active during the period of the weather warnings, with officials continuing to monitor the situation and work with frontline agencies to mitigate the impacts of the severe weather.
Bridge closures across Scotland
Forecast winds of 80mph around the Forth bridges would close the Forth Road Bridge, road management firm Bear Scotland said.
The Queensferry Crossing and Clackmannanshire Bridge would be closed to high-sided vehicles, motorcycles and cars with trailers or roof boxes in these circumstances.
Bosses from Transport Scotland have also confirmed wind speeds exceeding 75mph will force the closure of the Kessock Bridge.
Erskine Bridge may also face possible closures to high-sided vehicles between 6am and 11pm tomorrow as the amber warning is live.
The Dornoch Bridge and Cromarty Bridge could also be liable to closure during the storm, as well as the Skye Bridge.
Cabinet Secretary for Transport Fiona Hyslop said: “The Met Office has upgraded their weather warnings for Storm Eowyn to the highest level, which means there will be widespread disruption to the transport network.
“I would urge people to follow police advice and avoid travel in the area affected by the red warning for wind. If you do need to travel, your journey is likely to be badly disrupted and there will likely be cancellations to rail, ferry and air services.
“Traffic Scotland will provide the most up-to-date information on the trunk roads throughout the warning periods, via their website, social media channels and radio broadcasts.
“The conditions will inevitably cause major disruption to rail, ferry and aviation services too, so please contact your operator to see if your journey has been affected.”
Glasgow, East Ayrshire and East Lothian councils have said all schools and nurseries will be closed on Friday and other areas affected are expected to make announcements.
The Met Office red warning runs from 10am to 5pm and covers the central belt including Glasgow and Edinburgh, stretching north on the west coast to Jura in Argyll and Bute and south to Stranraer in Dumfries and Galloway.
Forecasters said the conditions bring a “risk of significant disruption to transport and power supplies as well as dangerous conditions outdoors”, with “very dangerous” driving conditions because of fallen trees.
They also warned of the potential for damage to buildings and homes.
