All mountain areas of Britain from Sunday 29th November 2015
A week of frequent upland gales and occasionally storm force upland winds, and particularly on western mountains precipitation at some stage almost daily resulting in considerable rainfall in total. Freeze-thaw cycles will occur on the Scottish Munros: the colder periods most lengthy, allowing snow to accumulate on higher areas. Further south, higher summits occasionally be below freezing point, but lying snow fairly transient. Some forecasts suggest a less wet, but perhaps still windy, period focussed on next weekend (December 5/6).
