Planning Outlook

All mountain areas of Britain from Wednesday 2nd December 2015

Continued bouts of severe upland gales over the next week to 10 days, although a possible lull in Scotland on Thursday this week, and perhaps England & Wales on Friday. On western mountains, precipitation at some stage almost daily resulting in considerable rainfall in total. Freeze-thaw cycles will occur on the Scottish Munros, although often sub-zero, allowing snow to accumulate. Further south, higher summits occasionally be below freezing point, but lying snow fairly transient.
