Mountain weather
Northwest Highlands Mountain weather forecast table
Confidence
High confidence for cold start, bright Saturday then milder with rain Saturday night becoming persistent and heavy west Sunday into Tuesday. Further unsettled conditions from Wednesday.
This evening forecast
The evening will begin dry with clear spells. Scattered showers, wintry above 900m, will spread east from late evening. Near gale westerly summit 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.
Mountain weather forecast
Cold and bright morning becoming cloudy with rain later. Summit winds will be near gale, occasionally gale, west to southwest.
