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.
hazard Heavy Persistent Rain
Heavy and persistent rain can lead to drenched clothing and footwear with waterproofs often becoming soaked through, especially if accompanied by strong winds. This can lead to significant loss of body heat and an increased likelihood of hypothermia. Terrain may turn increasingly boggy underfoot while streams can flood and become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.

Mountain weather forecast

Dry mostly cloudy morning. Heavy rain and summit snow afternoon and evening.

Additional weather information

Met Office Aberdeen meteorologist's view

Deteriorating conditions in the afternoon. Note very wet conditions will enhance the wind-chill effect.

Weather

Dry through the early hours and morning, some low cloud across western hills, but some bright or sunny spells north of the Cairngorm plateau. Cloud thickening around midday with persistent often heavy rain spreading north through the afternoon, turning to sleet or wet snow on the highest summits late afternoon. Rain and summit snow easing late evening, most hills largely dry by midnight.

Chance of cloud-free hill tops

30-40%, best chance in the north during the morning

Low cloud and visibility

Often good visibility to start across northern hills, with frequent cloud around 700m, mainly across southern hills, tops of the Cairngorm plateau may often be above the low level cloud. Visibility falling very poor in the afternoon as cloud lowers to 600-700m across all hills.

Weather

Showers merge to more persistent rain in the morning, falling as snow above 1100m, although north of the Cairngorms plateau likely to remain dry. Rain and summit snow breaking up to scattered showers through the afternoon, turning dry in the evening.

Chance of cloud-free hill tops

30% in the south, 60% in the north.

Maximum wind speed expected

Southwest 30 gusting 40 mph increasing to 40 gusting 50 mph for a few hours in the afternoon.

Temperature

  • At 800m Plus 2 or 3 Celsius.

Low cloud and visibility

Very poor visibility in frequent low cloud for most hills, bases 700-800m, but very good visibility north of the Cairngorm plateau where cloud likely to be mostly above the summits.
