Additional weather information
Meteorologist's view
Felling cold on the tops in persistent heavy rain and very strong winds. Gusts of 60mph or so will give very difficult walking conditions with progress highly impeded and a significant risk of being blown over. The rain will be heavy at times bringing drenching conditions for a time.
Weather
Mostly dry but increasingly cloudy before dawn with just a few showers and very strong southerly winds with gales or severe gales, best chance of clearer spells in the sheltered northeast. Occasionally heavy rain spreads northeast from around mid-to-late morning, clearing around early evening as winds ease down. Then mostly dry with increasing clear spells in the evening, but the odd shower possible in the west at first.
Chance of cloud-free hill tops
60% early morning, falling <20% during afternoon. Rising to >80% in evening.
Low cloud and visibility
Quite extensive areas of cloud down to 500-700m in the early morning, but some clear breaks in the sheltered northeast towards Bennachie and Aberdeenshire Hills. Cloud becomes more widespread as rain spreads east from mid-morning with visibilities falling moderate or poor. This breaking later through the afternoon with any patches of cloud in the evening often above summits and good or excellent visibilities outwith showers.
Ground conditions
No recent ground conditions report available.
