Brecon Beacons
Includes all higher summits in the southern half of Wales: the Bannau Brycheiniog / Brecon Beacons National Park, southern Cambrian Mountains and highest Preseli hills.
Monday'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 0 to 5C on higher summits. Feeling distinctly chilly on tops when stationary or where exposed to wind. Take appropriate layers.

Planning Outlook
Varying conditions over the next couple of weeks as areas of high pressure build across the British Isles then slip eastwards. Some dry and bright days with light winds mixed with periods of strengthening southerly winds bringing occasional rain coming in from the west - Thursday this week sees rain move increasingly onto western hills. Temperatures will vary, often lifting just above freezing to higher tops, but occasionally dropping back below freezing - chillier air briefly later this week. Some frosts into valleys. Remaining old snow cover on Scottish mountains stays largely consolidated with little change, patchy around highest tops in England and Wales.
