Mountain weather
Southwest Highlands Mountain weather forecast table
Confidence
High confidence for conditions to remain unsettled with outbreaks of rain throughout. Low confidence in any rainfall detail and timings from Monday onwards.
This evening forecast
Cloudy with a few showers in the south this evening, these wintry above 800m. Strong southeasterly winds. 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
Cloudy with a few wintry showers and strong winds at times. Very cold.
