Planning Outlook

Rain from time to time through the weekend as a shallow but complicated area of low pressure drifts across Britain. High pressure will then dominate, bringing several fine days next week. Scottish MR Note: Scot Gov has stated that "essential travel only must be undertaken" in order to protect our rural communities and prevent extra pressure on our Emergency Services. Now is the time to avoid unnecessary mountain activities and consider our social responsibilities. More info, visit: https://www.gov.scot/coronavirus-covid-19/
