Recent snow and increasing South West winds is expected to continue the wind slab development in the alpine and down to tree line.
The Nov 5 crust has facets growing above and below it, and exists up to 2500m on shady aspects and higher on solar aspects. New load from recent winds may make this layer more sensitive.
Deep persistent slabs are best managed by:
Cornices are best managed by:
A mix of sun and cloud for Sunday as the winds are forecasted to increase throughout the day, 30-80km/hr at ridge top from the South West. Temperatures will range from -2 to -7. Monday could see another 2 - 5cm of snow, strong to extreme winds and a slight cooling trend.
10cm of recent snow and strong Westerly winds suspected to be building wind slab in the alpine down to tree line. The Nov 5 facet/crust combo is down 50-80 cm and producing variable test results, but 'sudden' in fracture character. This crust extends up to 2500 m on N aspects and higher on solar aspects. Snow depths at treeline are 70-130 cm.
Evidence of natural avalanche activity within the past 36hrs up to size 2 (mainly sz 1-1.5) observed and reported throughout the forecast region consisting of cornice failures, wind slabs and loose dry sluffing.
