Wind Slabs
Look for these slabs in open lee areas and avoid large or planar slopes where they may be continuous. Feel for these with your poles as they become buried with new snow.
Aspects:
North, North East, East, South East, South.
Elevations:
Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 3
Loose Wet
Warming will create moist snow at lower elevations. Up to 15mm of rain are expected Wed and Thurs. Stay in low angle and supported terrain if you are skiing on moist snow. Remember small slides could be the large load needed to trigger deeper slabs.
Aspects:
All aspects.
Elevations:
Alpine.
Likelihood: Likely
Expected Size: 1 - 2
Persistent Slabs
Warming events this month have created two crusts below 1900m on shaded aspects and to ridgelines on solar aspects down about 50 and 100cm. Slabs may still be triggered on these deeper layers with large loads especially given the expected warming.
Aspects:
All aspects.
Elevations:
Alpine, Treeline.
Likelihood: Unlikely - Possible
Expected Size: 1 - 3
