Mountain weather
North Grampian Mountain weather forecast table
Confidence
High confidence in unsettled conditions. Moderate confidence for exact details on Tuesday and Wednesday, falling low for Thursday and Friday.
This evening forecast
A few showers into the southwest such as Drumochter Hills and Creag Meagaidh at first, but these gradually dying out. Otherwise dry with clear spells developing later in the evening. Freezing level around 1400m means there may be some wintriness, but confined to the very highest slopes. Fairly widespread cloud down to 600-800m at first in showers with visibilities falling moderate or locally poor. Increasingly clear summits later as showers die away. Strong southwest winds up to 30-40mph over the highest summits. Feeling cold at height.
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.
Mountain weather forecast
Rain, heavy in morning. Very strong winds - storm force later.

Additional weather information
Met Office Aberdeen meteorologist's view
Storm Bram will bring strong winds, storm force over summits, check the latest weather warnings to keep up to date. Gusts of 50-60mph above 800-900m through much of the day will give very difficult walking conditions with progress highly impeded and a significant risk of being blown over, increasing to storm force later will mean any mobility will be almost impossible on exposed ground with a risk of being blown off your feet. Feeling bitterly cold in strong winds.
Weather
Dry through the early hours. Rain pushes north through the morning with some heavy bursts at times. Drier for a time in mid-afternoon before cloud and mostly light rain spreads in from the west through the evening. Staying driest towards the sheltered northeast of Ben Rinnes and Ladder Hills. East to southeast winds strengthen in the morning, veering south, then southwest, with gales at all levels and storm force winds developing at height.
Chance of cloud-free hill tops
70% first thing, falling to 30% for most of the day, best chances in northeast.
Low cloud and visibility
Largely clear summits and good visibilities in early morning, with only patches of cloud around lower slopes and glens. More widespread cloud down to 600-800m spreads north through the morning with visibilities falling poor in hill fog or rain. Best chance of clearer summits towards the sheltered northeast.
