Mountain weather
South Grampian and Southeast Highlands Mountain weather forecast table
Confidence
High for most aspects of the forecast. A couple of hours uncertainty on timing of rain on Sunday, and low confidence in exact wind speeds and rain amounts on Tuesday and Wednesday.
This evening forecast
A dry evening and to start the night. Low cloud tending to break up over eastern Aberdeenshire hills, but persisting across Perthshire hills. Light to moderate southwest winds, 15-20 mph across the tops. Freezing level above the summits.
Mountain weather hazards
Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.
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.
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.
Heavy Persistent Rain
Heavy and persistent rain can lead to drenched clothing and footwear with waterproofs often becoming soaked through, especially if accompanied by strong winds. This can lead to significant loss of body heat and an increased likelihood of hypothermia. Terrain may turn increasingly boggy underfoot while streams can flood and become impassable. There may also be a risk of flooding in valleys or glens. If there is snow cover, a heightened avalanche hazard is possible and avalanche reports should be consulted where available.
Mountain weather forecast
Dry mostly cloudy morning. Heavy rain and summit snow afternoon and evening.

Additional weather information
Met Office Aberdeen meteorologist's view
Deteriorating conditions in the afternoon. Note very wet conditions will enhance the wind-chill effect.
Weather
Dry through the early hours and morning, some patchy low cloud across the Perthshire hills, but clear then sunny spells further north. Cloud thickening around midday with persistent often heavy rain spreading north through the afternoon, turning to sleet or wet snow on the highest summits late afternoon.

Chance of cloud-free hill tops
60% early morning, falling to 10% or less by the afternoon
