All mountain areas of Britain from Thursday 1st September 2016
Generally southwest or westerly winds this week will bring rain and low cloud in off the Atlantic from time to time, although in most areas total rainfall will be small, and cloud will often lift off the summits. Driest conditions will be Wales and southern Pennines. The weekend and early next week remains uncertain, albeit that the majority of forecasts bring swathes of rain, low cloud and strong winds east across Britain - at present though there is little consistency in forecast timing.
