In sintesi

Conditions remain dangerous due to recent snowfall and wind. You could trigger slabs up to 2 feet deep in wind-affected areas and up to 3 feet deep if weak layers below the new snow are triggered. Choose your route carefully and consider what is above you as remote-triggering an avalanche from below could be devastating.

    New and wind-loaded snow has added stress to buried weak layers formed during the month-long dry period in January. Triggering hard slab avalanches up to 3 feet deep is possible and more likely on N-NE aspects above 9,000'. Both wind-loaded and sheltered terrain should warrant caution due to the spotty distribution of the buried surface hoar and weak facets. 

    These slabs were triggered by snowmobilers near Grouse Mountain.  Similar, but deeper, avalanche activity is possible on very steep, shaded slopes today.

    Wind and storm slabs built from 10-14" of recent snow exist above 8,000'. These could produce a large enough avalanche to easily bury a person. Expect slabs up to 2 feet thick in wind loaded areas and much deeper if these step down to the deeper persistent layers. 

Avalanche Discussion

Temperatures warmed through the recent storm creating an upside down situation that was then capped by rain and mixed forms which are now a crust up to about 8,000'.  Above 8,000', riding conditions improve though snow is certainly dense. Wet loose slides below that elevation were observed yesterday though most were harmless and involved the upper six inches of the recent snow. Today's temperatures and wind should be cool enough to limit further wet activity but consider the destabilizing effect of sunshine on the upper snowpack in wind sheltered, confined and/or rocky terrain. A firm crust is present beneath the new snow on solar aspects which may not be entiorely bonded to the recent storm snow.
