Planning Outlook

All mountain areas of Britain from Tuesday 28th February 2017

Broadly unsettled over the next week to 10 days, with complex areas of low pressure influencing the British Isles. Precipitation frequent, often in the form of heavy showers - snow on the mountains. Some places will escape dry on certain days - confidence of day to day detail is low - northern Scotland generally faring best. Colder than recently, and across Scotland, mountain terrain substantially frozen all week, and intermittently so higher tops England and Wales, although temperatures will tend to rise slowly from the south later this week.
