Latest: 07/03/2014 16:52 FELL TOP CONDITIONS REPORT for Catstye Cam (890m) at 13:00 on Friday 7 March 2014. Although Spring is in the valleys, the high fells still retain a considerable amount of snow on sheltered east through to north facing aspects. There is no snow below 600m and isolated patches below 700m. Above 700m, the depth of snow increases with height although actual depth varies enormously from nothing at all on windswept aspects (often west and south facing slopes) to 90cm in drifts and hollows on east and north facing slopes above 800m. The steep final exit ramps from Striding Edge and especially Swirral Edge are covered with a considerable amount of unavoidable deep snow and ice. Exposed routes such as these should only be tackled by those experienced and equipped for winter mountaineering conditions. There are deep cracks in the cornices above east facing slopes, some of these 6m back from the edge, so do keep well back from the edge in these locations. Excellent low-visibility navigation skills are needed to avoid walking too close to the edge in these areas, as following footprints alone could take you far too close to unstable snow. There is already evidence of avalanche debris from slides off both the main face and Brown Cove. Full winter clothing, footwear and equipment are essential for anyone venturing onto the fells. For those going above the snowline and onto steep ground an ice axe and crampons are also essential. Temperature: minus 1.0 deg C. Maximum wind speed 53.5mph. Wind chill: minus 11.9deg C. Average wind speed: W 38.9mph.
