Planning Outlook

All mountain areas of Britain from Saturday 2nd August 2014

Confidence is presently very low over the weekend as a thundery low moves northwards across Britain. The low may remain shallow with fairly light winds and the rain patchy (although some heavy bursts), but moderate risk of the rain widely heavy and very extensive and gales or near upland gales developing by Sunday. The rain easing across Britain from the south on Sunday. Next week, winds generally off the Atlantic bringing rain from time to time and also low cloud, with western mountains most prone.
