Planning Outlook

All mountain areas of Britain from Friday 25th May 2018

Little change in the present pattern is likely over the coming week - little or no rain and frequently sunny with light wind across Scotland. Further south also some fine warm weather but interludes of cloudy, sometime thundery weather are likely. Although signals are weak, there may not be much change into early June. Much terrain will be very dry ('tinder dry') underfoot, particularly in Scotland. However, on some higher routes there remain significant patches of snow.
