Mountain hazards

Mountain weather hazards

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

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.
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 Storm Force Winds
Storm force winds (gusts over 70mph) make walking very strenuous with any mobility virtually impossible over exposed ground. Where these conditions occur there is a high risk of being blown over and even standing may be impossible at times with a risk of being blown off one’s feet. Basic tasks such as using a map, eating, putting on extra clothing or communication become extremely difficult away from any shelter.

Additional weather information

Met Office Aberdeen meteorologist's view

Note rapid rise in freezing level by the afternoon, some thaw of any fresh snow at lower elevations especially. Strong to gale summit winds will make for slow progress.

Weather

Starting off dry. Rain, preceded by snow, will spread east across all parts through the morning. The afternoon will be cloudy but drier with only some patchy light rain or drizzle. Persistent and widespread rain, heavy at times, will spread northeast in the evening.

Chance of cloud-free hill tops

30%, best chance first thing

Low cloud and visibility

Good visibility at first with patchy cloud down to 700 metres. However becoming poor in rain and snow through the morning with extensive low cloud developing down to 400 to 700 metres. Little change for most of the afternoon, however low cloud may become more broken from late afternoon or early evening onwards.
