Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High confidence for unsettled weather. Low confidence for details on Monday especially.
This evening forecast
Widespread cloud and rain over the Trossachs and island ranges at first, this sinking south through the evening. North of this, scattered showers feed in from the north, heavy at times and initially wintry above 900-1000m. Showers become more isolated through the evening as the freezing level falls to 700-800m. Westerly winds 30-40mph at first will gradually back northwesterly and ease through the evening. Feeling bitterly cold.
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.
Mountain weather forecast
mainly dry, bright. A few snow showers in north and around coast. Bitterly cold.
