High confidence for the general trend, but lower for detail of rainfall through Tuesday, particularly how far north this spreads. Southern areas most at risk.
A very windy end to the day with gales across most areas, and severe gales above munro level. Scattered showers will move quickly across the area with some clearer spells in between.
Gale force winds (gusts over 50mph) make walking difficult and strenuous with a potential to be blown over by gusts. There is often a marked increase in winds through cols or on exposed ridges and summits. Distances can take longer to cover and compass bearings become harder to follow accurately.
Wind significantly lowers the ‘feels-like’ temperature relative to the actual temperature, with even moderate winds significantly adding to the chilling effect. Strong winds can result in a severe and debilitating wind chill many degrees below the actual temperature. This effect will be enhanced in rain or wet snow. Without protection, prolonged exposure could result in frost nip or frostbite on exposed parts of the body and/or hypothermia.
Harmful UV levels from sunlight increase with altitude giving a greater risk of sunburn and eye damage, even on some overcast days. On breezy days, the cooling effect of wind on exposed skin may disguise any feeling of sunburn until it is too late. If there is snow cover, glare increases the effect of UV rays especially on the eyes. It is advisable to wear sun block, protective clothing such as a long-sleeved top and hat and have good quality eye protection.
Sunshine and scattered showers in the morning, cloudier with some rain across the south by late afternoon. Widespread upland gales, perhaps severe on summits through the morning.

Scattered showers will continue through the early hours, turning sleety above around 1000m, the majority of which will be confined to areas north of Torridon. Showers will start to die away through the morning, leaving most areas dry by midday with some sunshine. Cloud will thicken from the southwest through the afternoon, bringing outbreaks of rain across southern parts, mainly Skye and Glen Shiel by evening.
60% through the bulk of the day, with most slopes largely fog free away from showers. However, some capping cloud is likely above 700m across exposed western slopes, particularly the northwest. Decreasing to 20% in the south by evening as cloud lowers widely to 500m within rain.
Mainly very good with some far reaching views on offer, falling only temporarily in and around showers through the morning. Deteriorating to moderate through the later afternoon across the south, and locally poor in rain with some neighbouring slopes obscured.
Gusts may be closer to 60mph above 900m through the morning.
Thick cloud will remain in place across the area, bringing patchy rain and drizzle, mainly for the south through the morning. Clearer conditions will arrive from the west by late morning, bringing a return to scattered showers and some sunshine. Into the evening, showers will become more widespread and heavy with a risk of thunderstorms, mainly for Assynt and northwards.
Light through the morning, with a westerly breeze of 20-25mph with gusts to 40mph developing through the later afternoon.
20% with hill fog quite widespread above 500m, this slowly clearing from the west by mid morning. Generally 60% through the rest of the day with some fog associated with showers.
Moderate or poor at first, but improving to very good by around midday and falling temporarily during showers, perhaps to poor in any heavy showers.
