Planning Outlook

All mountain areas of Britain from Sunday 23rd October 2016

Substantially dry on all mountain areas and winds often light over the next week to perhaps ten days, although wetter conditions at times across the W & NW Highlands around the middle of next week. Otherwise, cloud will come and go, and occasionally areas of low cloud and rain will affect some areas, principally eastern mountains this weekend. Summit temperatures generally just above freezing point this weekend, but will tend to rise through next week.
