Confidence

High for a lot of dry bright weather with a chance of a few showers, but lower confidence that this will last through the weekend as areas of rain and mountain snow start to affect parts of the country.

This evening forecast

Perhaps the odd shower at first, wintry on summits, otherwise a dry evening with cloud breaking. Moderate northeast breeze and freezing level dropping to 900m.

Mountain hazards

Mountain weather hazards

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

hazard 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.

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

Mainly dry, bright though rather cloudy. Freshening southerly summit winds.
