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.
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 a few showers, rain spreading east in the afternoon.

Additional weather information

Meteorologist's view

Quite cool in brisk northwesterly winds which may be gusty around showers at times. Winds quite strong on the summits during the evening.

Weather

A few showers overnight but a few clearer spells too. A lot of bright or sunny weather during the day but a few showers too, mostly moving through quite quickly. Clouding over later in the day as some light rain spreads in from the west during the late afternoon, turning heavier later in the evening.

Chance of cloud-free hill tops

70%, patchy low cloud in association with showers.

Low cloud and visibility

Patches or areas of low cloud above 600m at times associated with showers during the day, with visibility likely to fall moderate in any heavier showers for a time. Any early mist or fog should clear steadily during the early morning.

Ground conditions

No recent ground conditions report available.
