Windy, walking impeded
Blustery conditions enough to give buffeting on higher terrain or affect balance on exposed ridges. 25 to 40mph.
Frequent or persistent rain
Steady rain fairly persistent, occasionally heavy, rather wet underfoot.
Poor visibility
Murky conditions with areas of fog shrouding the hills, making navigation challenging. Map and compass essential.

Much of Scotland dry with sunshine; areas of low-level fog and frost. Some showers toward the far north. Fog from lower elevations upward for Pennines and east Wales, but much of northwest Wales and the Lakes have clearer hills. Rain moves into south Wales. Strong easterly winds for Wales.
Headline for Brecon Beacons
Windy, gusty. Fog and low cloud, rain moving in.
How windy? (On the summits)
Southeasterly 25 to 30mph, gusty 35mph in places around major summits and some western downslopes.

Rain becomes fairly persistent
Dry at first, but rain develops from south to affect much of the region increasingly, with time steadier or heavier falls particularly southern areas, mixed with drizzly moments, patchier northwards.
Cloud on the hills?
Extensive, some varied fog in morning
Varied extent of low cloud and fog early in day, eastern areas foggy to low levels, but further west some breaks higher up. Some slopes between layers for a time, but cloud likely to fill in widely to shroud the hills, in places from low slopes up.
Chance of cloud free summits?
10%
Sunshine and air clarity?
Overcast and dull, foggy lower areas toward east and south in the morning. Poor visibility fairly widely as rain develops.

Planning Outlook
Dropping colder across all mountains during midweek as the wind shifts northerly and strengthens. Some showery snowfall across the Highlands on Wednesday, otherwise plenty of sunshine and very clear air late this week, for all areas - clearing away fog from early in the week. Into the weekend, as the wind shifts west then southwesterly, less cold air drifts in from the Atlantic bringing more cloud onto western hills - an increasing risk of rain in the west. A changeable outlook into next week with varying temperatures, stronger wind at times, rain and some upland snow possible. Unsettled patterns are more likely to prevail beyond mid-month.
