Mountain hazards

Mountain weather hazards

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

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.
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.

Mountain weather forecast

Cloudy with outbreaks of rain, occasionally heavy, , accompanied by hill fog. Some brighter spells later. Fresh to strong south or southwest winds on the mountains.

Additional weather information

Meteorologist's view

Wet ground will bring slippery conditions on rocky surfaces with navigational difficulties adding to the day's hazards.

Weather

Cloudy, with outbreaks of rain arriving in the early hours and continuing on and off for much of the day. The rain turning heavy at times especially towards Ben Alder, but with a few drier interludes, then likely brightening up towards evening through with further showers.

Chance of cloud-free hill tops

Little chance until late afternoon then rising 70%

Low cloud and visibility

Extensive cloud with bases 600-800m, becoming more broken later in the day but with some persistent banks above 900m. Even outside cloud, heavier outbreaks of rain and drizzle will also bring moderate to poor visibility.

Ground conditions

No recent ground conditions report available.
