Mountain hazards

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.

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.

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.
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.

Additional weather information

Meteorologist's view

In the morning walking will be extremely difficult on exposed ground with a high risk of being blown over. Although winds are less strong for much of the day there remains a risk of being blown off balance and energy output significantly increased when walking into the wind.

Weather

Cloudy with patchy drain or drizzle and a few showers, and very strong winds including storm-force gusts on the summits. Heavy rain spreading northeast from shortly before dawn. This clearing north by around midday to become dry and sunny in the afternoon. A few showers will spread north through the evening, these heavy at times. Remaining windy throughout the day.

Chance of cloud-free hill tops

Little chance morning. Rising to >80% by midday.

Low cloud and visibility

Quite widespread cloud down to 300m or lower in the morning and visibilities falling poor in hill fog and heavy rain. This gradually clearing through the morning to leave summits largely clear and good or excellent visibilities in the afternoon, but occasionally dropping temporarily moderate or poor should any showers pass through in the evening.

Ground conditions

No recent ground conditions report available.
