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 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.

Additional weather information

Meteorologist's view

Windy conditions in the early morning will make for fairly arduous walking on exposed terrain with buffeting of clothing. Balance may be affected at times. Note that winds should ease through the day. Feeling cold at height so suitable clothing is advised. Widespread low cloud and hill fog so good navigation skills will be required.

Weather

A dull day with widespread low cloud. Some light rain or drizzle in the morning. Mainly dry in the afternoon, but chance of the odd shower. Some clearer spell developing towards evening.

Chance of cloud-free hill tops

10% or less, rising to 40% in evening.

Low cloud and visibility

Widespread cloud down to 300-400m through the day and visibilities falling poor in hill fog. A few breaks developing through the late afternoon and evening.
