Mountain hazards

Mountain weather hazards

Hazards apply at or above 300m, reflecting the more severe conditions which can occur at altitude.

hazard 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.
hazard 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.

Additional weather information

Met Office Aberdeen meteorologist's view

Heavy persistent rain in the afternoon and evening will provide soaking conditions in addition to potentially slippery pathways and some fast-flowing watercourses.

Weather

Extensive low cloud with mist or hill fog and outbreaks of light drizzle in the morning. This will gradually lift and break through the morning, with perhaps some bright spells around midday. A band of heavy persistent rain arrives in the afternoon and persists through the evening with strengthening northerly winds.

Chance of cloud-free hill tops

Generally less than 10% but 40% for a time from late morning to early afternoon, the best chances in the west.

Low cloud and visibility

Extensive low cloud combined with mist, light drizzle or fog from valley level up to 1000m in the morning. This lifts and breaks to allow some patchy broken cloud at 500m and some clearer breaks through the middle of the day. Cloud becomes more extensive once again later with bases down to 200-300m and very poor visibilities in heavy persistent rain.
