Planning Outlook

All mountain areas of Britain from Wednesday 28th January 2015

Upland winds frequently near gale force this week, perhaps occasionally easing toward the weekend as a low pressure becomes a broader feature across Britain. From Wednesday on, much colder conditions will extend south to all areas, with snow to lower slopes, most concentrated on northern and western facing mountains. A cold pattern is very likely to last through the weekend and into early next week, with most terrain remaining frozen.
