Summary for all mountain areas

Strong to gale force winds across Scottish mountains in the morning, becoming confined to the northwest. Rain in the W/NW Highlands from dawn will fade and pull away northwards. Low cloud and patchy drizzle continues to affect many western hills of Britain, but some breaks tending to form, best toward eastern hills.

Southwesterly in the range 30 to 40mph; risk 50mph for a few hours in the morning west coastal hills.

Walking arduous or perhaps at times in the morning difficult. Strongest winds not necessarily on higher tops.

How Wet? (Precipitation and its impact)

Early rain clearing to patchy drizzle.

Rain persistent for a few hours from dawn, heaviest on western mountains. Will tend to gradually fizzle out and clear northwards, although patches of drizzly rain may come and go through the day on west coastal hills.

Planning Outlook

All mountain areas of Britain from Saturday 24th August 2019

Southerly winds over the next few days will bring much warmer temperatures than recent weeks, and feeling humid. A few showers may affect western Scottish coasts on Saturday, but most places will be dry through the weekend and Monday, with light winds and sunshine, hazy at times. Many hills often free of low cloud. By Tuesday into midweek, as fronts edge back in from the west, bursts of rain are likely to develop, locally thundery. Southwesterly winds are expected to prevail later in the week, with rain at times, most frequent in W/NW Scotland. Some windy days with possible gales for the Highlands.
