WEDNESDAY: Mostly clear skies with moderate westerly winds. with isolated flurries. Light winds. Freezing level valley bottom, high of -15. 

Small human triggered dry loose avalanches were triggered on Saturday as snowfall began to accumulate. 

We expect human triggered slab avalanches to have occurred on Sunday, within the storm snow. 

20-30cm of recent snowfall sits over a melt freeze crust on solar aspects at all elevations, and wind effected surfaces in exposed terrain. In sheltered terrain features a small layer of surface hoar may exists above the melt freeze crust.

A layer of buried surface hoar sits 30-50cm deep in the upper snowpack, most likely to be found and triggered on north aspects in sheltered areas. This layer has produced variable results in recent snowpack tests, and could be triggered by very large loads such as a cornice fall or step down avalanche. 

The lower snowpack is well consolidated, with a crust/facet layer found 80 to 150 cm deep. It is currently considered dormant, but could become active later this season. Check out the forecaster blog for more information. 

• The new snow could use a day or two to settle and stabilize before we start to tee up the bigger lines.
• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Minimize exposure to sun-exposed slopes when the solar radiation is strong.
