Fell Top Conditions on Tuesday 25 February
Readings from Helvellyn summit at 00:05
Temperature minus 2.9°C Maximum wind speed 21.4mph Wind chill minus 11.7°C Average wind speed 17.6mph Wind direction WSW - SW
Fresh snow and hail fell overnight and continued as showers during the day. Although it was hailing down to 200m, it was only really settling above 400m adding to existing accumulations. Once again, this fresh snow fell with an accompanying W to SW wind. Above 400m the average snow depth rises with height; however, the actual depth varies considerably from little, or nothing, on aspects prone to the wind to drifts of 100cm although such depth is the exception. The greatest accumulations are found in sheltered spots and hollows and on east and north facing aspects where, especially above 850m, there was quite a bit of windslab where care needs to be taken. Above 700m, and especially above 800m, paths and ground not covered by snow was covered by large patches of ice.
There are cornices on the edges of north and east facing aspects. Limited visibility only allowed a brief inspection, but they have grown over the past 48 hours, so please keep well away from such edges and advise those with less experience to do likewise.
Full winter clothing (waterproofs, warm layers, hat & gloves), footwear and equipment are essential for anyone venturing out onto the fells. For those going above the snowline and attempting, or traversing, steep ground, an ice axe and crampons are also essential. This is even the case on easier angled terrain, such as the approaches and parts of the summit plateau, owing to the amount of ice on the ground although microspikes would be sufficient here. Exposed routes above the snowline, such as Swirral and Striding Edges, are in winter condition and should only be attempted by those experienced in, and equipped for, winter mountaineering.
Climbers do be aware of unstable cornices and windslab and please only attempt routes if you are certain that they are in condition and that you will not damage the rare alpine plants either on the climb or on the approach to it. Please refer to the BMC "White Climbing Guide" for details.
