Summary for all mountain areas
Severe conditions becoming widespread and lasting onward into the night and Wednesday - stormy conditions, hurricane-force winds on higher mountains. Heavy rain sweeping northwards across Scotland during the day, breaking up into showers for England & Wales; flooding likely.
Headline for The Northwest Highlands
Soon heavy rain, increasingly stormy winds.
How windy? (On the Munros)
Southeasterly, an hour or so from dawn 30mph or less in north, rapidly strengthening in morning to 50-60mph, soonest Skye; gusts 70mph develop, turning S'ly afternoon. Rising further by dusk onward to reach SW'ly 90-100mph evening into night.
Effect of the wind on you?
Deteriorating during the morning to make mobility difficult on exposed terrain, powerful gusts could knock you over on downslopes N/W of major hill groups. Later increasingly severe conditions low-levels upward, damaging gusts.
How Wet?
Near-constant rain sets in, flood risk
Rain arrives in the south as dawn breaks and rapidly spreads widely, setting in persistent and heavy for several hours, beginning to break from the south afternoon, but showery rain in west, in evening frequent or setting in again; into night turning to snow above 1000m. Beware fast-rising streams and flood risk.
Cloud on the hills?
Becoming extensive
From dawn, shrouding high ground from Skye towards Ben Wyvis, some eastern Munros further north as well. Northwest coast clearer tops just after dawn. Deteriorating widely, from lower or middle slopes upward, though bases always highest west coast north from Torridon.
Chance of cloud free Munros?
Lowering to less than 10%
Sunshine and air clarity?
Soon widely overcast and dull. Poor visibility as rain sets in, though northern areas in particular starting good.
How Cold? (at 900m)
3 or 4C, rising to 6 to 8C for several hours, then lower again later, to 2C into night. Feeling like -10C in strongest daytime wind; colder into the night.
Freezing Level
Above the summits until after dark, then lowering to just touch the highest Munro summits overnight (1100m+).

How windy? (On the Munros)
South-southwesterly 40 to 60mph, some uncertainty of peak speed, risk 70mph+ west coastal mountains.
Effect of the wind on you?
Widely arduous, but risk of more difficult or severe conditions ongoing, particularly western areas.
How Wet?
Risk rain on and off west
Pulses of rain may run in from the southwest, greatest risk more persistent on Skye, sometimes passing northward, but much of Sutherland more often dry.
Cloud on the hills?
Most persistent on and near Skye
Covering the Cuillin and nearby coastal hills on mainland most of day, lowest in rain to mid-slopes. Further inland, capping tops for periods, some local breaks north.
Chance of cloud free Munros?
30%
Sunshine and air clarity?
Glimpses of sun mainly north and east, often cloudy west. Hazy, visibility poor in rain.
How Cold? (at 900m)
4C, may start to drop into evening. Feeling near -10C in the wind.
Freezing Level
Above the summits
Planning Outlook
A very unsettled pattern as southwesterly winds prevail and low pressure systems move in from the Atlantic, sustained gales over the mountains, severe or stormy for periods. Temperatures only close to freezing on higher Scottish tops this week, even here will experience spells above freezing with thawing, leaving snow increasingly patchy, but beware some icy surfaces on the very highest tops where some refreezing occurs. Drier for most places on Thursday this week, otherwise rainfall will be frequent and heavy, sometimes showery with hail. Expect wet ground conditions and further flooding of streams and some rivers.
