Mountain weather
South Grampian and Southeast Highlands Mountain weather forecast table
Confidence
High confidence for generally unsettled weather with spells of strong wind and rain. Confidence lowers from Sunday in regard to detail and timing of rainfall events.
This evening forecast
Cloudy with outbreaks of rain and summit snow through the evening. Fresh southeasterly winds but strong over highest ground. Freezing level 1100m.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
Gales
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
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.
Blizzards
Blizzards and whiteouts present challenging and serious conditions due to a combination of falling or blowing snow, strong winds and cold temperatures. They can be highly disorientating, often resulting in near-zero visibility with limited or no visual references and no distinction between ground and sky. Cliff edges and cornices may not be apparent, even close up. These conditions require very good navigational skills.
Storm Force Winds
Storm force winds (gusts over 70mph) make walking very strenuous with any mobility virtually impossible over exposed ground. Where these conditions occur there is a high risk of being blown over and even standing may be impossible at times with a risk of being blown off one’s feet. Basic tasks such as using a map, eating, putting on extra clothing or communication become extremely difficult away from any shelter.
Mountain weather forecast
Mostly cloudy with outbreaks of sleet and snow, drier through the afternoon. Gale force winds on the hills later.

Additional weather information
Met Office Aberdeen meteorologist's view
Strong winds with rain and snow give a risk of severe wind chill. Appropriate warm and waterproof clothing needed. Tricky navigation at times with low cloud and strong winds, which may make for difficult walking conditions.
Weather
Cloudy with rain and snow on hills through the early hours. Rain and snow dying out through the morning with some bright spells developing. Cloudier again through the evening as heavy rain and snow spread northeastwards. Snow falling above 600m. Strong southeasterly winds reaching severe gale, perhaps storm force on the highest ground, later in the day with a risk of severe wind chill.
Chance of cloud-free hill tops
20%.
Low cloud and visibility
Low cloud with bases 700-900m throughout the day. Tops mostly covered in cloud but a few brief breaks and bright spells possible in the afternoon. Visibility good outside of cloud.
