The Nov 11 Crust may become touchy due to the additional load the recent storm snow and moderate south winds have added.
Weather Forecast
Saturday will bring cloudy skies, an alpine high of -3, approximately 15cm of new snow and light South winds. Freezing levels expected to stay below 1600m.
Snowpack Summary
~20cm of HST in past 24hrs on the Parkway with L-M SW winds forming soft slab in lee features. Nov 11 crust (10cm of laminated ice layers) down 50cm @ TL and can be found between 2100-2600m on all aspects and will be a layer of concern as the snow load increases. The lower pack is well settled to ground.
Avalanche Summary
Recorded 1 Sz 2.5 in a cross loaded gully feature, W aspect 2300-2800m in Nigel Basin. Had poor visibility into the Alpine but suspect additional activity has occurred.
Confidence
Due to the number of field observations on Friday
Problems
Wind Slabs
Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
