Additional weather information
Meteorologist's view
Gusts of around 40-50mph will give difficult walking conditions with a risk of being blown off balance. Navigation could be challenging with energy output significantly increased when walking into the wind. Feeling chilly at height.
Weather
Occasionally heavy rain and strong winds will clear northeast in the early hours. Then mostly dry and bright in the morning with just the odd shower in the early afternoon. Staying mostly dry with bright spells and just a few showers for the Aberdeenshire and Angus hills, becoming cloudy further south with showers or longer spells of rain, heavy at times. Winds strengthen again later with a chance of summit gales. Chilly at height.
Chance of cloud-free hill tops
In north: 75%. In south: 75% in morning falling 40% from afternoon.
Low cloud and visibility
Mostly clear summits and good or excellent visibilities for the Aberdeenshire and Angus hills with just the odd patch of cloud around 1000m and visibilities temporarily falling moderate as any showers pass through. Also generally good visibilities and clear summits further south in the morning, but cloud becoming more widespread down to 700-900m and visibilities occasionally falling poor in any heavier rain through the afternoon and evening.
Ground conditions
No recent ground conditions report available.
