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 before dawn to 50-60mph, local gusts 70mph, turning southerly by midday. Strengthening further during afternoon to reach 80mph, up to SW'ly 100mph by evening into night higher Ben Nevis group.
Mobility difficult on exposed terrain all day, 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, damaging gusts.
Near-constant heavy rain, local flooding
Rain from the south pre-dawn, spreading widely and setting in persistently and heavy, most intense southern areas. A breaking trend afternoon though showery rain will linger, into evening frequent or setting in again; into night turning to snow above 1000-1100m. Beware fast-rising streams and local flooding.
Soon extensive
Widely shrouding the coastal slopes from lower slopes upward and locally down to coastal cliffs in the south. Highest bases from Ben Nevis group towards Knoydart early morning, but soon extensive to 600-700m. Odd breaks southwest later.
Less than 10%
Overcast and dull. Poor visibility.
3C pre-dawn, soon rising to around 8C, then sharply cooling from the south later, to 2C evening into night. Feeling like -10C in strongest daytime wind; colder into the night.

Frequent showery precipitation, merging to be near-constant at times, falling as snow above 1000m, also hail mostly morning.
Often covering high tops
Cloud base constantly changing, but often shrouding higher slopes, at times down to 600m coasts, brief breaks to tops inland.
20%

South-southwesterly 40 to 60mph, some uncertainty of peak speed, risk 70mph+ high tops and coastal mountains.
Widely arduous, but risk of more difficult or severe conditions ongoing, particularly toward coasts.
A little rain in the wind
Occasional pulses of rain may run onto coastal areas in the west. Spots of rain in the wind elsewhere, some slopes often damp, but small amounts of rain in total.
Most persistent south/western areas
Covering many hills all day, to some mid-slopes near coasts, but mostly above 900m inland, breaks higher up north and east of Rannoch Moor and Ben Nevis.
30%
Glimpses of sun mostly near Glen Spean. Hazy, visibility reduced if rain occurs.
4C, may start to drop into evening. Feeling near -10C in the wind.
Above the summits, may then drop onto Ben Nevis top into night (1300m+).
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.
