Northwest Highlands

This evening forecast

Clear spells and scattered showers this evening with a chance of hail and lightning. Excellent visibilities and often clear summits outside of showers, but cloud falling to 700m or so and visibilities falling poor as showers pass through. Strong southerly winds 35-50mph, some gusts around 60mph possible at first.

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.

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.

Mountain weather forecast

Bright spells and scattered heavy showers. Rain and cloud in evening. Breezy and chilly at height.

Additional weather information

Meteorologist's view

Gusts of 40-50mph over the highest summits at times will give difficult walking conditions with a risk of being blown off balance. Navigation could be challenging with energy output significantly increased when walking into the wind.

Weather

Mostly dry with bright or clear spells to start but a scattering of occasionally heavy showers over Skye and the west coast These showers edge further inland to affect most areas from mid-morning. Showers fading and becoming dry for a few hours in early evening before widespread cloud and rain spread east later in the evening. Best of the bright and dry weather in the relatively sheltered north and east. Feeling chilly at height despite any sunshine.

Chance of cloud-free hill tops

40% southwest, 70% northeast

Low cloud and visibility

Quite extensive areas of cloud around 600-800m in the west around Skye and Torridon and visibilities falling temporarily poor as showers pass through. Best chance of broken cloud and clearer summits in the sheltered northeast.

Ground conditions

No recent ground conditions report available.

Mountain weather information

Weather

Occasionally heavy and showery rain crossing east in the early morning. A brief respite a few hours after dawn before another band of occasionally heavy rain crosses from late morning, clearing later in the afternoon. Clear spells and a few further showers in the evening. Feeling chilly on the tops in rain, cloud and blustery winds. Moderate chance of lightning.

Chance of cloud-free hill tops

20% much of the day, best chance northeast. Rising 60% in evening.

Maximum wind speed expected

South veering southwest 35-50mph at times, easing later.

Temperature

At 800m Plus 4C to plus 7C.
Glen Plus 11C rising to plus 16C by day.
Freezing level Above summits - falling to 1200-1400m in evening.

Low cloud and visibility

Quite widespread cloud down to 500-700m and visibilities falling poor in rain and hill fog through much of the day. Best chance of clearer spells in the relatively sheltered northeast. This gradually clearing and breaking through the late afternoon to allowing some good or excellent visibilities and clear summits between showers.

Ground conditions

No recent ground conditions report available.
