Planning Outlook

All mountain areas of Britain from Friday 20th October 2017

Late Friday into Saturday, another Atlantic storm threatens widespread heavy rain and gales, especially England & Wales. A changeable outlook continues: south to south-westerly winds dominating into next week, with frequent rain on all western mountains, but the most prolonged falls perhaps focused on England & Wales rather than Scotland. Fairly mild overall; occasional sleet or snow only temporarily on highest tops.
