Parts of Scotland have been hit by snow and severe gales as the country continues to feel the effects of Storm Gertrude.

Met Office amber warnings for snow, ice and high winds have expired, but yellow "be aware" warnings for ice and snow remain in place across all of Scotland into Sunday.

The weather is set to remain unsettled into next week, with more warnings in place for the arrival of another storm on Monday.

The Met Office said the vigorous low pressure system - named Storm Henry - is expected to pass just to the north of Scotland, bringing very strong west or southwesterly winds across much of the UK.

Due to heavy snow on Saturday afternoon, motorists were advised to avoid the A9 at Drumochter Pass at Dalwhinnie, if possible.

Routes in Tayside were particularly affected by snow, with a number of collisions reported during the morning, particularly on the A90.

On the A82, snow gates were closed at Tyndrum, Bridge of Orchy and Glencoe.

They were also closed on the A93 from Braemar to Glenshee, the A939 from Tomintoul to Cock Bridge and the A821 Duke's Pass. Officials told drivers to take extra care on the A832 at Glen Docherty and the M74 at Johnstonebridge.

The Western Isles Emergency Planning and Coordinating Group met on Saturday.

It advised against travel during a spell of strong winds forecast between 3pm on Monday and 3am on Tuesday.

The group said: "Based on the information available, in respect of this weather warning, the advice would be for people not to travel during these times, due to the risk of wind gusts of 80-90 mph, also very large waves are expected, which may lead to over-topping and localised flooding of coastal roads."

The Met Office warned that a mix of snow and strong winds would continue to cause difficult driving conditions.

"Frequent wintry showers, heavy at times, are expected across northern UK during Saturday," the Met Office said.

"The heaviest snow showers are most likely north-west of the Central Belt of Scotland. Here, away from the immediate coast, around 5-10 cm of snow could accumulate. Elsewhere, snow accumulations will be more localised, with around 2-5 cm possible, primarily above 100 metres.

"Widespread gales are also expected with some gusts of 70mph across northern and western Scotland at times. Here, drifting of snow is likely in strong to gale force winds with local blizzard conditions, particularly on high ground."

Travel conditions remain difficult across large parts of the country.

Three people were killed in a crash between a car and a van on the M9 on Friday night.

Police Scotland issued the following advice for motorists affected by the adverse conditions:

"• Slow down and leave plenty of room to stop. You should allow at least three times more space than usual between you and the car in front.

• Brake gently to avoid skidding. If your wheels lock, ease off the brakes.

• Turn on your lights to increase your visibility to other motorists and always clear all ice and snow off the car windows before setting out.

• Drive slowly on snow in the highest gear possible.

• Do not assume your vehicle can handle all conditions. Even four-wheel drive vehicles can encounter trouble on winter roads.

• Visibility is often reduced because of fog, rain, spray, hail or snow. Remember to ensure that you use dipped headlights in periods of reduced visibility. Fog lights can only be used when visibility is seriously reduced to less than 100 metres but must be switched off if visibility improves."
