Planning Outlook
High rainfall over the southeastern Highlands during Friday brings a risk of flooding here as the weekend begins. A deep area of low pressure moves toward northwest Scotland into the weekend to bring widespread rain and gales, stormy conditions develop over many mountains, the strongest sustained winds over Scottish tops into Sunday in excess of 70-80mph with more powerful gusts. Temperature will vary, briefly above freezing to all tops, then back just below zero on Scottish Munros by Sunday with frequent showers of hail and snow on high mountains. Atlantic west-southwesterlies remain dominant next week, bringing several low pressure systems with rain and wind, punctuated by brief clearer windows. Flooding is possible as rainfall totals build.
