Mountain weather
South Grampian and Southeast Highlands Mountain weather forecast table
Confidence
High confidence on the largely cloud Sunday afternoon, but some uncertainty on the extent of precipitation. High confidence on strengthening SE winds by Tuesday.
This evening forecast
Any rain, summit snow clearing, then clear spells and patchy fog developing in glens. Windy on tops.
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 cloudy with mist and fog. Rain and hill snow in afternoon. Strong winds on tops.

30% decreasing to 10% by afternoon.
Low cloud and visibility
Poor or very poor visibility at lower levels in mist and fog. Perhaps better visibility on some higher summits for a time before cloud bases become extensive down to 600m or lower in the afternoon.
