Planning Outlook

All mountain areas of Britain from Tuesday 24th September 2019

Low pressure will dominate the weather all week, bringing frequent rain and low cloud, and intermittently strong upland winds. As several areas of low pressure track across the country, the weather pattern will often be complicated, making day to day local detail difficult to forecast. However, there remains strong evidence that the driest area will be areas near and north of the Great Glen.
