Additional weather information
Meteorologist's view
In the early morning walking will be extremely difficult on exposed ground with a high risk of being blown over. Although winds are less strong for much of the day there remains a risk of being blown off balance and energy output significantly increased when walking into the wind. Risk of localised flooding and heavy-going conditions underfoot as a result of heavy rain in the early morning.
Weather
Cloudy with heavy rain spreading northeast through the early morning, with very strong winds and storm-force gusts on the summits. This clearing north from around mid-morning to become dry and sunny for a time. A few showers will spread north through the afternoon and evening, these heavy at times with a very small chance of hail and lightning. Remaining windy throughout the day.
Chance of cloud-free hill tops
Little chance early morning. Rising to >80% by midday, falling 60% again in evening.
Low cloud and visibility
Quite widespread cloud down to 300-500m in the early morning and visibilities falling poor in hill fog and heavy rain. This gradually clearing through the morning to leave summits largely clear and good or excellent visibilities, but occasionally dropping temporarily moderate or poor as any showers pass through, these more frequent through the evening.
Ground conditions
No recent ground conditions report available.
