Snow and sleet over the tops.

Mild conditions at present with a forecast for cooler temperatures and more snow down to 600 metres during the early part of next week.   The main event at present is the potential for the Great Slab in Coire an Lochain to release.  Note the large crevasse  developing below the buttresses.

Mild with a spring snowpack

Warm, Sunny but Very Windy

Looking into Coire an t Sneachda 

Recent avalanche debris due to cornice collapse below cliffs

diminishing snowpack
The pictures do not tell the whole story of course - in this case the winds on the plateau were storm force South-Westerly and up to 80mph - The snowpack is very soft due to warm temperatures, mainly surface instabilities on steeper slopes, progressively getting worse as the temperatures rose during the day. Still very good snowcover on the plateau.

Very windy - becoming milder.

Heading toward the saddle - a frozen Loch Avon below.

Coire an t Sneachda with large cornices overhanging slopes
Generally a very good snow cover but winds getting increasing stronger made progress quite difficult later in the day.

Winter still hanging on!

A glimpse of the Cairn at Summit of Fiachail a Choire Chais
New snow on all aspects above 950 metres, thinly covering many rocky areas though. Very little wind, quite muggy !. Could not see enough to get an idea of cover on the plateau, but would expect it to be quite good. Very soft snow, some surface releases on steep slopes.

New Snow on the Tops

Looking South toward the Saddle 
New accumulations of deep snow on East through South to South-West aspects, in steep and convex  places especially, this is unstable. A very soft weak layer at around 60cm depth. Elsewhere though the snow is very good.

Winter Saturday on Cairngorm

Summit temperatures on Cairngorm were still below freezing on Saturday morning and it was windy.   Failures were identified in the surface windslab during field observations.  

In exposed locations snow was being transported and redistributed in the strong South-West winds.


Cracking underfoot below. Strong winds and significant snow forecast for Saturday evening and into Sunday. Still fantastic ski touring conditions. Skiable snow right to Cairngorm Car Park.
Possibly milder during the coming week and the prospect of more snow next weekend!

A change in the weather

 10mph winds first thing this morning and by mid afternoon nearly 60mph.

Billowing clouds over the Cairngorms as winds increase

My skis were soon buried from drifting snow!

Friday, April 12, 2013

Intense sunlight during the morning


       


 The overall snow cover is still very good for ski touring , although variable and a little sluggish in places.

Looking up towards Coire an t-Sneachda, some nice large basins of snow.

Avalanche debris from the previous day below jacobs ladder and the central gully area.  Weak sugar like facetted grains are still within the snow pack presenting snowpack weaknesses especially in areas of steep and convex terrain.

Winter is still very much here !
