Outside of the red warning area, the rest of Scotland will be covered by amber and yellow alerts for wind and snow for much of the day.

An amber warning for wind covering everywhere north of Perth, including Orkney and Shetland, lasts from 06:00 on Friday until 06:00 on Saturday.

Another amber warning for wind covering everywhere south of Perth, though sweeping up the west coast encompassing the Isle of Mull, lasts from 06:00 until 21:00 on Friday. This will include the areas affected by the red alert after 17:00

Meanwhile, a yellow warning for snow, starting at 06:00 on Friday until midnight, covers parts of central Scotland, Tayside, Fife, Grampian, the Highlands and Islands and Argyll & Bute.

A further yellow warning for snow and ice covering the northern mainland and central belt, from midnight until 11:00 Saturday, was issued by the Met Office on Friday morning.

It is estimated up to 25cm of snow could fall in areas above 300m, but icy stretches are expected to form on untreated surfaces across the country as temperatures fall below freezing.

Other amber and yellow alerts for wind are also in place on Saturday.
