West Highlands
Western Highlands accessible from, and south of, Glenfinnan (Road to the Isles) and Glen Spean (includes Creag Meagaidh). This area includes Ben Nevis and the mountains around Glencoe. In the east, from Ben Alder south to Loch Lomond and Trossachs NP. Also Arran and Mull.
Wednesday's Forecast
Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Patchy rain or drizzle
Rain on and off, or generally drizzly - total amounts small, but may be persistently damp, especially where hills are shrouded in cloud.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.
Chilly
Air temperature typically 1 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Cloud on the hills?
Extensive near west coast
Cloud extensive on high ground, especially where rain is frequent. Struggling to lift above 600m near the west coast. Higher chance of breaks well inland.
Chance of cloud free Munros?
20%
Sunshine and air clarity?
Mostly overcast with layers of high cloud. Visibility very good if dry, reduced to poor if areas of rain develop.

How windy? (On the Munros)
Forecast details still uncertain. Southwesterly 35 to 45mph, risk sustained 55mph. Very gusty.
Effect of the wind on you?
Difficult walking conditions will make progress challenging. Very powerful gusts may easily blow you over. Significant wind chill.

Likely wet near coast
Heavy, on-and-off showers likely near the west coast, especially Lochaber. These may merge to become persistent rain. Chance of Loch Lomond NP and Arran remaining dry.
Cloud on the hills?
Extensive where raining
Extensive cloud down to coastal slopes where in rain. Regions that remain dry will have a much higher cloud base, which may be above the summits over Loch Lomond NP and Arran.
Chance of cloud free Munros?
50%
Sunshine and air clarity?
Little or no sun in many places, but patchy or widespread sunshine if out of rain. Poor visibility near the coast.

How windy? (On the Munros)
Forecast details uncertain. West to southwesterly 30-45mph. Chance of a lull to 20-25mph in afternoon.
Effect of the wind on you?
Feeling blustery with balance affected at times, especially morning. Significant wind chill.
How Wet?
Showery
Showers on and off through the day, particularly near the coast in Lochaber. There is a chance these may fade in the afternoon. Only a few 'spots in the wind' well inland.
Cloud on the hills?
Widespread
Cloud shrouding most higher ground, especially near the coast. Base will lower and cloud thicken during and after any showers. Highest cloud base will be well inland, but is unlikely to clear the summits.
Chance of cloud free Munros?
20%
Sunshine and air clarity?
Glimpses of weak sunshine at times. Poor or very poor visibility.
How Cold? (at 900m)
7C. Feeling below -5C in the wind.
Freezing Level
Above the summits.
Planning Outlook
Extensive rain and gales into midweek, likely wettest on west-coastal regions. Areas of rain and showers frequently in the forecast later in the week. Temperatures near-average, but feeling cool when exposed to wind. A chillier northwesterly may emerge by next weekend, briefly dropping near freezing on the highest Scottish tops. Indications then favour higher pressure at least briefly expanding northwards early next week for some drier days, but unlikely to settle down for long.
