Previous mod to strong SW winds have created new wind slabs, these are now buried by 10 cm of new snow in the Icefields area.
This is a complex problem. The spacial variability and potential consequences of triggering a large avalanche on this layer makes it extremely difficult to gain confidence in the snowpack. Consider this before entering bigger features.
Deep persistent slabs are best managed by:
Cornices are best managed by:
A steady SW flow will bring light winds and light precipitation to the region over the weekend with a pulse of 10 cm possible on Sunday night. Temps will cool slightly but remain above seasonal values For more detailed analysis: Mountain Weather Forecast
The snowpack is highly variable across the forecast area. The surface snow is becoming more cohesive and is bonding well. The upper snowpack remains mainly facetted, particularly in shallow areas where there is less than 60cm of snow. There is inconsistent bridging in the mid-pack over the weak basal facets and depth hoar.
No avalanche patrol today and no new avalanches reported. Wednesday's helicopter flight observed only two recent large cornice failures that initiated avalanches in the weak basal facets and one windslab avalanche.
