Planning Outlook

All mountain areas of Britain from Tuesday 23rd September 2014

A change to westerly winds across all mountain areas will bring rain bearing fronts in from the west, particularly during the mid-week period. Nevertheless, away from the W & NW Highlands of Scotland, total rainfall will be small. Often windy, with one or two periods of upland gales across Highland Scotland. Next weekend may become substantially dry again, particularly England and Wales. Many mountain areas are now very dry indeed underfoot.
