Transport chiefs have warned of travel disruption on Wednesday as winds of up to 90mph are forecast to hit Scotland.

The Met Office has issued an amber warning of wind for much of central, southern and western Scotland between 9am and midnight on Wednesday.

Gale or severe gale-force winds - 60 to 70mph - are expected across all parts of the country with 90mph gusts possible in exposed coastal areas of the west.

Transport bosses said the high winds could lead to bridge closures in exposed areas and some coastal flooding. They warned that travel disruption is likely even though transport networks are expected to be quieter than usual, with schools and many businesses still on holiday.

Transport Minister Keith Brown urged those planning to travel tomorrow to plan their journeys in advance and to drive with caution.

He said: "High winds can make travel more hazardous and it is important that people are aware of the conditions on the roads and any consequent delays or disruption so they can plan their journeys accordingly.

"Drivers should be alert to the potential for bridge closures, overturned vehicles and fallen trees and should drive with caution, avoiding unnecessary risks.

"The Scottish Government's resilience team are monitoring the situation as it develops and standing by to step up emergency response arrangements as necessary. The power companies are also prepared to deal with any power cuts."

For most areas, the strongest winds will sweep in from late morning and through the afternoon, although the eastern Highlands and north-east Scotland will see the strongest winds during the evening. The winds will be accompanied by blustery showers which will be heavy and prolonged over west and central Scotland, with snow on hills.

Winds of 70mph could see exposed bridges closed to high-sided vehicles and double-deckers. Some low-impact coastal flooding is also expected along exposed western and northern coasts from Ayrshire and Arran to Shetland.
