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.
Heavy rain and increasingly stormy winds.
Southeasterly rapidly strengthening from dawn to 50mph, gusts 60-70mph higher Cairngorms developing, turning southerly by midday. Strengthening further during afternoon to reach 80mph, up to SW'ly 100mph by evening into night higher Cairngorms.
Soon deteriorating from dawn to make mobility difficult, powerful gusts could knock you over on downslopes N/W of major hill groups. By later daytime and after dark, increasingly severe conditions low-levels upward.
Persistent rain soon sets in, flood risk
Patchy rain arrives from the southwest before dawn, soon spreading widely with heavy bursts well into the day. A breaking trend into showery rain later, though later evening frequent or setting in again; into night turning to snow above 1000-1100m. Beware fast-rising streams and flood risk.
Soon extensive
Fog over the high Cairngorm plateau and down to middle southern slopes soon fills in widely across middle slopes, down to low slopes in the south. Highest bases northwest Cairngorms and north Monadhliath, 500-600m.
Less than 10%
Soon widely overcast and dull. Poor visibility.
3 or 4C, rising to 7 or 8C for several hours, sharply cooling later, to 2C into night. Feeling like -10C in strongest daytime wind; colder into the night.
Above the summits until after dark, then onward into night lowering to around 1200m.

South-southwesterly 40 to 60mph, some uncertainty of peak speed, possibly 70mph higher Cairngorms.
Widely arduous, but risk of more difficult or severe conditions ongoing on higher mountains.
Little or no rain
Spots of rain in the wind at times, but amounting to little, some places dry all day.
Mostly southern areas
Banks of cloud on some slopes, most common Drumochter around to some areas accessed from Braemar, may cling over tops. Good breaks northward.
50%
A little sun mostly toward north. Slight haze possible, but mostly good visibility.
4C, may start to drop into evening or night. Feeling near -10C in the wind.
Above the summits
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.
