Mountain weather
North Grampian Mountain weather forecast table
Confidence
Medium confidence in exact rain and wind detail on Wednesday. High confidence for unsettled weather through the period, but low confidence in details from Thursday onwards.
This evening forecast
Storm Bram brings storm-force southerly veering southwesterly winds, gusting over 90-100mph over the highest summits bringing a serious risk to safety. Quite widespread cloud down to 800-1000m brings poor visibilities in rain or hill fog, though chance of clearer summits in the sheltered northeast. Feeling bitterly cold as the freezing level, initially above summits, falls to 1000-1200m by midnight.
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.
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.
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.
Thunderstorms
Lightning is a significant mountain hazard which can result in serious injury or death. Mountain terrain often leaves one highly exposed to lightning strikes. Hail may give unpleasant conditions with torrential rain and localised flash flooding also possible, mainly in Summer months.
Mountain weather forecast
Very windy with gale to storm-force winds. Heavy showers, rain later.

Additional weather information
Met Office Aberdeen meteorologist's view
Occasional storm-force winds over the highest summits means any mobility will be almost impossible on exposed ground with a risk of being blown off your feet. National severe weather warnings are in force so keep up to date with the latest forecast. Feeling bitterly cold in strong winds and frequent showers.
Weather
Gale-force gusts to low levels throughout the day with severe gales or occasional storm-force gusts at height as Storm Bram, lying to the north of Scotland, moves slowly east. Heavy showers spread in from the west, wintry above 900-1000m and with a chance of hail and lightning, becoming more frequent for a time during the middle of the day. Easing off for a time in the afternoon, before more persistent rain spreads east through the evening.
Chance of cloud-free hill tops
30% best chances in the northeast.
Low cloud and visibility
Quite widespread cloud down to 800-1000m visibilities falling poor in frequent showers.
