Mountain hazards

Mountain weather hazards

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

Strong Sunlight
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.

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.
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

Mainly cloudy with some showers, some heavy with the small chance of lightning. Light to moderate breezes.

Additional weather information

Meteorologist's view

Shower and cloud detail uncertain. Medium UV levels mean sun protection will be required.

Weather

A mainly dry morning with some bright or sunny intervals. Some heavy showers will break out in the afternoon and early evening, with the slight chance of lightning. The showers becoming light and isolated during the evening.

Chance of cloud-free hill tops

80% falling 30% in north and 60% in south

Low cloud and visibility

In morning some cloud at times above 1000m, then during the afternoon as winds swing round to the north or northeast, lower cloud at 500-700m feeding into the Monadliaths, Northern Cairngorms and the Cromdale Hills, and some lowering also possible further south later. Visibility away from cloud occasionally poor in the heavier showers but mainly good otherwise.
