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 Cairngorms NP and Monadhliath

Upland gales; snow, threat setting in south. Whiteout.

How windy? (On the Munros)

Westerly, often 40 to 50mph, risk occasional gusts to 60mph, but particularly southern areas, may drop to 30mph for an hour or so.

Effect of wind on you?

Difficult walking across the hills. Severe wind chill.

How Wet?

Snow, setting in south; whiteout

Pulses of snow extending across the region, falling to lower slopes, and west of A9 & southernmost Cairngorms NP, may well set in over many hours. Mostly light and patchy northern-most areas. Whiteout very likely south. Very wet underfoot.

Cloud on the hills?

Extensive across the hills

Breaks toward 1000m rarely, most likely Deeside. But will deteriorate as cloud lowers, often to or below 600m southern Cairngorms NP west to Ben Alder. Elsewhere, cloud base typically 600 to 900m.

Chance of cloud free Munros?

Less than 10% most areas; 20% north-east.

Sunshine and air clarity?

Rare if any sunshine. Visibility increasingly poor due to precipitation and near zero in snow and cloud.

How Cold? (at 900m)

-3C; but may feel as cold as minus 20 Celsius where exposed to wind.

Freezing Level

Close to or below freezing from most glens upward.

Planning Outlook

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).
