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 West Highlands

Gusty upland winds. Near-constant snow. Whiteout.

How windy? (On the Munros)

Westerly risk often 40mph, occasional gusts over 50mph, but for several hours, likely a lull to 25-30mph. Deteriorating to 50-60mph from west toward and after dark.

Effect of wind on you?

Often uncomfortable walking across the hills, at times difficult high tops. Severe wind chill.

How Wet?

Snow setting in; whiteout

Snow soon extensive across the region, rarely ceasing all day, heaviest western mountains, falling from lower slopes up inland, or above 500m west coast & Arran. Whiteout very likely. Very wet underfoot.

Cloud on the hills?

Extensive across the hills

Breaks above 900m well inland temporarily. But frequently almost blanket low cloud, sometimes from lower slopes up coastal hills and widely below 600m.

Chance of cloud free Munros?

Less than 10%.

Sunshine and air clarity?

Sunshine not expected. Visibility frequently poor due to precipitation and near zero in snow and cloud.

How Cold? (at 900m)

-2C south, to -4C north; but at times feeling colder than minus 15 Celsius where exposed to wind.

Freezing Level

500m north & well inland; nearer 700m west coast & south.

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).
