Summary for all mountain areas
Severe conditions, particularly England & Wales - storm force upland winds, plus prolonged rainfall, easing only later to showers. Winds not as strong in Scotland, but often gale force. Frequent to near-constant snow across most of the Highlands, falling to lower slopes, giving whiteout.
Headline for The Northwest Highlands
Upland gales. Frequent snow, may set in. Whiteout.
How windy? (On the Munros)
Westerly 40 to 50mph, strongest toward north, risk 60mph north from Assynt, squally gusts around showers.
Effect of wind on you?
Difficult walking across the hills. Severe wind chill.
Frequent snow and hail; whiteout
Pulses of showers, widely snow from lower slopes up inland, or above 400-500m near west coast, frequent, or merging to give constant precipitation for an hour or more, particularly afternoon; risk hail and possible thunder. Whiteout very likely. Very wet underfoot.
Cloud on the hills?
Extensive across the hills
Breaks above 900m well inland, most frequent Sutherland. But toward west, cloud often from lower slopes up, particularly coastal hills south of Wester Ross.
Chance of cloud free Munros?
Less than 10% west; 20% north-east.
Sunshine and air clarity?
Rare if any sunshine. Visibility frequently poor due to precipitation and near zero in snow and cloud.
How Cold? (at 900m)
-3C, falling later to -5C; but locally feeling as cold as minus 20 Celsius where exposed to wind.
Inland close to or below freezing from just above glens upward; 500m around west coast.
All mountain areas of Britain from Monday 30th 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. Indications favour a less wet, but perhaps still windy, period focused on next weekend (December 5/6).
