Planning Outlook

All mountain areas of Britain from Thursday 27th September 2018

High pressure, generally centred over or near S Britain will bring extensively dry conditions over the next 10 days. However, around the periphery of the high in Scotland, intermittently windy (particularly north), and weakening fronts will bring occasional rain southwards. Higher Munros often close to freezing point, and slight frost many valleys some nights.
