Planning Outlook

All mountain areas of Britain from Wednesday 5th August 2015

Remaining unsettled. Fronts pushing northwards on Wednesday will bring rain and strong winds to many mountains. Improving by Thursday, becoming mainly dry with much lighter winds. Friday brings mainly light winds but the risk of some slow moving heavy showers. A brief ridge of high pressure is expected to build around Saturday, but thereafter the pattern is likely to become west-south-westerly, bringing strengthening winds, particularly to Scotland, and risk of rain on many western mountains by Sunday.
