Planning Outlook

All mountain areas of Britain from Tuesday 2nd September 2014

A long period of fine, often sunny and very warm weather with light wind for almost all mountain areas. However, cloud will come and go on higher areas of W Scotland until later in the week, and as winds turn easterly, low cloud will also affect the Pennines, and occasionally hills in east Wales. Just the threat of a little rain in some areas on Friday before becoming fine again.
