In sintesi

The Nov 11 Crust may become touchy due to the additional load the recent storm snow and moderate south winds have added.

    Be cautious of wind slab in immediate lee and cross-loaded terrain in the alpine, particularly where the crust exists (up to 2600m all aspects).

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
