Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

hazard Severe Chill Effect
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.
hazard Poor Visibility
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.

hazard Gales
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.

The Southwest Highlands weather forecast area is an extensive area of mountains, moorland, islands and sea lochs. The area has a high density of steep and rugged Munros (Scottish mountains over 3000 feet) including the highest mountain in the British Isles, Ben Nevis (1,344 metres), attracting an estimated 100,000 ascents a year. The 700 metre cliffs of the north face are among the highest in the UK, providing classic scrambles and rock climbs of all difficulties for climbers and mountaineers. Glen Coe is also an iconic area for rock climbing and scrambling and includes the Aonach Eagach, an exposed and narrow ridge which stands 900m above the floor of the glen below.

The Loch Lomond and Trossachs National park was the first of the two national parks in Scotland and includes Ben Lomond which is the most southerly Munro. Running past the foot of Ben Lomond is The West Highland Way which is Scotland's first long distance walking route. It stretches for 96 miles from Milngavie on the edge of Glasgow to Fort William.

The Isle of Arran is in the far south of the area, often referred to as Scotland in miniature, it includes Goat Fell with its fine panoramic views and the Glen Rosa horseshoe with sections of rock scrambling.
