Storm Abigail threatens to bring lightning, heavy downpours, and winds of up to 90mph.
Motorists have been warned to expect disruption on the roads and residents were told that problems with power supplies will be affected.
The motoring group RAC said: "The 'invisible' force of the wind can lead to vehicles unexpectedly being knocked off course, sometimes with devastating consequences."
All classes in Shetland and the Western Isles were suspended.
Operations director Drew Collier said: "There is a clear warning that major weather related disruption to ferry services on the Clyde and Hebrides routes is likely later this week.
"I would urge people to factor this in when making travel plans. The sea conditions we are expecting could well be too treacherous to sail in."
Sky's weather presenter Nazaneen Ghaffar said: "Eventually the winds will ease through the day as Abigail moves away, however it'll still be windy for all areas with blustery showers.
"Some of these showers could still turn wintry across the high ground of Scotland, northern England and perhaps Wales."
