Mountain weather
Northwest Highlands Mountain weather forecast table
Confidence
High for trend to changeable but milder southwesterly type, medium for daily details, lower on Sunday.
This evening forecast
Skye and Wester Ross cloudy with occasional mainly light snow, though some moderate outbreaks possible over the Cuillin bringing summit blizzards, with rain below 200-300m and patchy hill fog. The north and east of the area staying dry. Strong to gale southeasterly winds.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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.
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.
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.
Mountain weather forecast
Cloudy, some occasional light rain and hill snow developing. Less windy but still a strong south or southeasterly on the summits.
