Planning Outlook

All mountain areas of Britain from Friday 22nd September 2017

Day time temperatures will be relatively warm through the next week as south or southwesterly winds become persistent. Conditions will continue to be mixed into early next week as low pressure in mid Atlantic pushes a series of fronts across the UK. Western mountains will be wettest and frequently covered in fog, with periods of strong winds and upland gales, especially during Saturday and again early next week.
