Mountain hazards

Mountain weather hazards

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

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.

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.
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.

Additional weather information

Meteorologist's view

Conditions quickly improving after early heavy rain clears but expect swollen watercourses and flooding of some paths. Feeling chilly, note the sub-zero wind chill on tops.

Weather

Heavy and potentially thundery rain soon clears east during the morning leaving the rest of the day mainly dry with sunny spells and just the odd light shower. Fresh to strong winds on summits.

Chance of cloud-free hill tops

20% rising to 90% by afternoon.

Low cloud and visibility

Patches of cloud with bases 500-700m during early heavy rain will lift above most tops by afternoon. Visibility will be generally very good, but deteriorating to a few kilometres or less in early rain.

Ground conditions

No recent ground conditions report available.
