A weak front will bring low cloud and a little rain slowly southwards to areas near the Irish Sea. Dry weather will follow, although the NW and later W highlands will deteriorate in the afternoon as the wind strengthens, and further low cloud and rain comes in.

Headline for The Northwest Highlands

Deteriorating afternoon: windier; low cloud and rain.

How windy? (On the Munros)

Southwesterly, strengthening from about midday from 20 to 25mph to by mid to late afternoon, 25 to 35mph; the strongest winds on coastal mountains, and least Ben Wyvis and near the Great Glen.

Effect of wind on you?

Mostly small, although ease of walking will be impeded on higher areas, and toward west coast into the afternoon, expect significant buffeting.

Substantially or completely dry in morning, and away from western mountains into the afternoon. But rain and drizzle will increasingly set in from west afternoon, most persistent coastal mountains.

Cloud on the hills?


Persistent cloud likely to shroud the mountains, although breaks to higher slopes in morning, and into the afternoon well inland. Increasingly through afternoon, cloud forming below 500m western mountains and 700-900m elsewhere.

Chance of cloud free Munros?

30%; dropping to 10% from west through afternoon

Planning Outlook

All mountain areas of Britain from Wednesday 24th September 2014

A change to westerly winds across all mountain areas will bring a series of fronts, bringing bands of low cloud and rain, in from the west, particularly mid-week. Nevertheless, away from the W & NW Highlands of Scotland, total rainfall will be small. Blustery, with upland gales on Thursday and Friday across Highland Scotland. Next weekend and early next week is likely to become substantially dry again, particularly England and Wales. Many mountain areas are now, and will remain very dry underfoot.
