Fell Top Conditions on Wednesday 17 January
Readings from Helvellyn summit at 12:00
Temperature minus 3.4°C Maximum wind speed 47.1mph Wind chill minus 14.2°C Average wind speed 22.6mph Wind direction W
A day of squally snow and hail showers, with fresh snow right down to valley level in many parts of Cumbria. On Helvellyn the snow has gathered on lee slopes, and the depth varies enormously. At 300m there were drifts behind boulders and spurs to a depth of 100cm, and up to 180cm at 800m. These depths were the exception however, with much scouring on any slopes exposed to the winds.
In sheltered places there is a dramatic build up of snow that is very poorly bonded to the layers beneath. At between 720m and 800m in Broad Gully on Brown Cove Crags the layering consisted of a very hard bottom layer of old snow, covered with up to 40cm of graupel (hail), covered with up to 10cm of windblown slab. This windslab was breaking into very large chunks, the size of table tops, with very little weight from the assessor's foot, and sliding down on the graupel which acts as ball-bearings on the hard surface below. This is exactly the kind of dangerous snow build-up that the assessor mentioned starting to see yesterday. There is a very similar snow profile on major slopes facing NW through E to SE, but also more localised on smaller slopes that are sheltered from the wind. On these aspects there is a High risk of avalanche. This includes headwalls, the tops, flanks, and aprons of gullies, tops of ridges (including Striding Edge and Swirral Edge) and buttresses, and open slopes.
Another weather feature today was the variable visibility. This was at times good, but extremely poor in falling snow. Good navigational ability is essential in these conditions.
Climbers will note the information on avalanche-prone slopes above, and if thinking of a climb will pick a suitable route accordingly. Buttresses looked very thin today, and turf is only frozen in patches above 800m.
Anyone heading into the hills at present will need the full range of winter mountain walking gear, experience, and technical knowledge. An ice axe and crampons are essential, as is a map and compass.
