All mountain areas of Britain from Tuesday 1st December 2015
Frequent upland gales and occasionally storm force upland winds this week and perhaps well into December. 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. Slight improvement as pressure builds around Friday-Saturday, but still windy, and risk some further rain in north-west.
