Confidence

High confidence for most of Friday, although some uncertainty in the extent of showers later. High for generally dry and breezy conditions over the weekend but some uncertainty in the location of a weak front which may bring some light rain at times to the west.

Mountain hazards

Mountain weather hazards

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

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.

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.

Mountain weather forecast

Low cloud and patchy rain at first, mainly dry and bright afternoon. Rain later. Windy.

Strong and gusty winds with gales on the high plateau areas and summits in the morning. UV levels in the afternoon will be quite high with a chance of sunburn, even in cloudy conditions.

Weather

Cloudy with light and patchy rain at first, dying out through the morning. Mainly dry in the afternoon with a little brightness coming through but also a few brief showers. Outbreaks of rain spreading northeast in the evening, heavy at times.

Chance of cloud-free hill tops

20% in the morning, best chances in sheltered northeast. Becoming 90% in afternoon. Chances decreasing again in the evening.

Low cloud and visibility

Extensive cloud in the morning with bases 600 to 800m but this will become patchier and clearing in the afternoon. Cloud becoming extensive on the tops again late in the evening. Away from low cloud, the visibility will be mainly good.
