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.

Effect of the wind on you?

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.

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.
