Mountain hazards

Mountain weather hazards

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

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.

hazard 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.
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.

Mountain weather forecast

Mostly fair by day. Rain developing into evening. Summit gales.

Additional weather information

Meteorologist's view

Gales and most severe wind chill confined to the higher routes.

Weather

Most staying dry through the day with occasional bright spells, but the odd light, isolated shower may appear. Cloud thickening from the west into the evening bringing patchy rain, which turns heavier and more persistent towards midnight.

Chance of cloud-free hill tops

70% by day

Low cloud and visibility

Good or very good becoming moderate or poor in rain or showers, very poor within cloud which occasionally lowers to 800m by day.

Ground conditions

Date: Wednesday 10 December Location: Helvellyn summit at 12:05 Full report: Saturated ground, horizontal rain & hail. The back end of Storm Bram has been reluctant to move on. Although its tail winds were evident from the car park, the morning remained relatively dry with only a few fast-moving showers. The real sting came at Helvellyn summit around noon, after an ascent via a relatively sheltered Swirral Edge. Here, the full force of near 50 mph west-south-west winds, combined with driving rain and hail, made for harsh conditions. By early afternoon the weather had deteriorated further, with persistent heavy rain falling onto already saturated ground. Streams became swollen, and even normally insignificant becks were a challenge to cross. As a winter storm, Bram has been marked by its unusually mild temperatures, pulling air from the Atlantic and North Africa. This was evident with readings of +5°C at Red Tarn and +3°C on the summit. Despite this, hail and wind chill produced conditions equivalent to feeling like -5.5°C. This thoroughly tested winter clothing including a warm hat and gloves, which is essential. Only the thinnest remnants of snow remain, lining the upper edge of Brown Cove (East). Swirral Edge and Striding Edge are completely snow-free. A walking pole proved useful for maintaining balance on the exposed summit plateau. The weather is expected to settle somewhat on Thursday and Friday, though conditions will remain changeable. Poor weather is forecast to return over Saturday or Sunday. Temperature: plus 3.0C, Maximum wind speed 49.2mph, Wind chill: minus 5.5C, Average wind speed: 40.6mph
