Weather hazards

Gales Low likelihood Hide detail

Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.

Learn more about gales

Severe chill effect Low likelihood Show detail

Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.

Poor visibility Low likelihood Show detail

Poor visibility presents challenging route finding conditions. Visibility could be significantly less than 50 metres in all directions with few or no visual references, especially on featureless moors or plateaux. Distances become hard to judge and cliff or cornice edges can be difficult to recognise. These conditions require good navigational skills. There is a risk of white-out conditions when mist or fog is combined with extensive snow cover.

Weather

Some showers continuing overnight with clear periods. A bright day on Sunday with sunny spells and further showers. Showers will be most frequent over Skye and the Northwest Highlands with the odd heavier one. Fewer showers and more sunshine further east towards Ben Wyvis. Some of the showers on highest peaks will be of sleet, adding to an already significant chill effect.

Chance of cloud-free mountain/hill tops at 800m

60% although higher in east of area. Patchy cloud cover around 700 to 800m becoming more extensive near to showers, especially in west.

Visibility

Away from showers the air will have great clarity with more distant tops being clearly visible. There will be temporary reductions as showers pass by.

Met Office Aberdeen meteorologist's view

Note strengthening winds on the tops during afternoon and evening giving an increasing chill effect.

Chance of cloud-free mountain/hill tops at 800m

Separated from the Grampians by the Great Glen the region includes Sutherland, Ben Wyvis, Wester Ross, The Cuillin, Glen Affric, Glen Shiel and Knoydart.

The Cuillin Hills on the Isle of Skye are among the steepest mountains in the UK and include 15 peaks above 3,000 feet (900 metres). There are two main ridges; the magnificent Black Cuillins and the Red Cuillins around Loch Coruisk to the south.

Torridon has some of the most spectacular mountain scenery in Scotland which includes Beinn Eighe, a long ridge with many spurs and summits, two of which are classified as Munros. Beinne Eighe also includes Britain's first ever national nature reserve where you may spot golden eagles, buzzards, pine martins and wild cats on your travels.
