Ground conditions

Latest: 20/12/2014 16:04 FELL TOP CONDITIONS REPORT Date: Saturday 20 December Location: Helvellyn summit at 12:30 The slow thaw continues - it was zero degrees on the summit. There is now little snow on paths below 850m and what does remain is avoidable. Above 850m snow coverage depends on aspect with little, if any, on slopes subject to strong westerly winds. Conversely in sheltered hollows and on east facing slopes there are drifts of mainly soft snow up to 60cm although such depth is the exception. The summit plateau was covered in verglas (thin ice) making walking demanding in the strong winds. Full winter clothing and footwear are essential for those venturing out onto the fells. For those going above the snowline and attempting, or traversing, steep east facing slopes an ice axe is recommended; for some routes it is essential. For example the exit to Striding Edge retains a steep patch of unavoidable snow; should this snow freeze then crampons would also be useful. Temperature plus 0.1deg C. Maximum wind speed 39.2mph. Wind chill minus 9.4 deg C. Average wind speed WNW 30.2mph.

Mon 22 Dec 2014

Generally another wet and cloudy day. Rain will persist across the park for most of the day and is likely to be heavy at times meaning becks and rivers will be in spate and difficult to cross.

Hill Fog

Persistent down to 500m, especially over western fells, with patches down to 200m.

Max wind above 500m

Southwesterly 50-55mph gusting 70-75mph becoming westerly during the morning and gradually easing down to 30-35mph gusting 45-50mph by the evening.
