Ground conditions

Latest: 07/12/2016 16:07 The Fell Top Assessors Report Wednesday 7 December, Helvellyn summit at 1145: A wet, warm and wild day on Helvellyn today. The thaw of what little snow remains continues, and there is now hardly any snow at all below 700m. There are still some extensive patches above this height, but by and large they are easily avoidable. The ground on both Swirral and Striding Edge was mainly wet, bare rock, however on Swirral Edge in particular there are still a few patches of snow persisting. On exits from both Swirral and Striding Edges onto the summit plateau today the snow had all but gone, but not quite completely. Any lowering of the temperature over the next few days (although not currently forecast) would soon turn these remaining patches into very hard snow. Owing to this, for those attempting exposed routes above the snowline, an ice axe might still be found useful. Throughout the morning the cloud base hung at around 350m, and heavy rain eased occasionally to a mere drizzle. Gale force SW winds made the crossing of both edges challenging, and had the wind turned more to the south Striding Edge in particular would have been out of the question. The other notable challenge today was navigation, with visibility reduced for much of the time to around 10m. Full winter clothing, footwear and equipment are essential for those venturing out into the fells, as despite the milder summit temperature, the windchill remains well below zero. A map and compass and the knowledge of how to use them are essential. Temperature: plus 7.9 deg C, Maximum wind speed 57.8mph, Wind chill: minus 3.6 deg C, Average wind speed: 39.5mph.

Fri 09 Dec 2016

Another dull day with extensive hill fog. Some patchy drizzle, then more persistent and occasionally heavy rain setting in during the late afternoon and evening.

Visibility

Moderate to poor.

Hill Fog

Widespread 300-500m with lower patches in the west.

Max wind above 500m

South to southwest 35 gusts 45mph increasing 50 gusts 65mph during the dat.

Temperature

Valleys:
Plus 9 Celsius overnight rising Plus 12 during the day and Plus 9 in the evening.
800m:
Plus 6 Celsius easing down to Plus 4 in the evening.
Freezing level:
Above the summits.

Sat 10 Dec 2016

A brighter day with hill fog becoming much more patchy. A fresh to strong westerly breeze on the summits and freezing levels just above the tops.

Sun 11 Dec 2016

Another fairly bright day with sunny intervals. Quite breezy on the summits and feeling cold there with the freezing level around 900m.

Mon 12 Dec 2016

It may start dry but the unsettled weather continues so it looks like cloud, rain and summit snow will spread from the southwest accompanied by strong to gale force south or southwest winds.
