Mountain weather
South Grampian and Southeast Highlands Mountain weather forecast table
Confidence
High confidence in the south to southeasterly wind direction continuing throughout, and strengthening on Tuesday with increasingly unsettled conditions thereafter.
This evening forecast
Cloudy with extensive hill fog, bases 600m or lower and outbreaks of rain, falling as snow above 900m
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
Patchy mist and fog but some sunny spells. Fresh to strong winds on tops.
