Mountain weather
North Grampian Mountain weather forecast table
Confidence
High for unsettled weather on Sunday and Monday. High for a change to dry conditions on Tuesday and Wednesday. Low for detail on Thursday.
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.
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.
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 rain at times, drier in the north. Windy.

Additional weather information
Met Office Aberdeen meteorologist's view
Increasingly windy through day with summit gales. Wind speeds will reach 70 mph across the Cairngorm Plateau, increasing to 90 mph after dark. Progress will be slow with a risk of being blown over. Note rising freezing level through the afternoon.
Weather
Starting off dry before widespread rain, preceded by snow, extends northeast across all parts in the morning. The afternoon will be drier before further outbreaks of rain spread northeast in the afternoon, but the more northern Cairngorms and Monadhliath may stay dry until dark. Rain will become more persistent and widespread in the evening.

Low cloud and visibility
Poor in areas of cloud down to 700 to 900 metres, cloud bases lowest and most extensive across Rannoch Moor, Ben Alder and Creag Meagaidh. Cloud bases somewhat higher across the north of the region.
