Planning Outlook

All mountain areas of Britain from Thursday 2nd October 2014

Fine most mountain areas on Thursday, but upland gales extending across the Scottish Highlands from the west, and areas of low cloud Wales and S Pennines, mainly morning. From Friday very much more unsettled, upland gales intermittently, and areas of constant rain and also showers frequently. Generally colder. Underfoot, away from the W & NW Highlands, still very dry - although progressively less so, particularly western mountains.
