Avalanche Summary
A few small wind slab avalanches were triggered by skiers and naturally on Wednesday. They were on all aspects, in steep terrain, and at treeline and alpine elevations. The slabs were generally 10 to 20 cm deep.
Snowpack Summary
The storm that began on Thursday is expected to deliver 10 to 15 cm of new snow by the time it ends on Friday night. The new snow adds to 5 to 10 cm of snow we received on Tuesday. Forecast winds are expected to shift from west to east, meaning that new wind slabs will likely exist on varied aspects, as well as in cross-loaded terrain features on Saturday. In sheltered areas at and below treeline, the new snow has buried pockets of feathery surface hoar crystals and soft, faceted snow.In the south of the region, the remainder of the snowpack is well-settled. In the north of the region, around 50 cm of snow may overly a weak layer of surface hoar or faceted grains.
Problems
Wind Slabs
More snow on Friday night is expected to produce fresh wind slabs in exposed areas. With shifting winds in the forecast, new slabs may form on a variety of aspects. These slabs may not bond well to underlying faceted snow.
Watch for patterns of wind loading as you venture into wind affected terrain.Be especially careful around wind loaded pockets near ridge crests and roll-overs.Seek out sheltered areas where the new snow is unaffected by wind.
Aspects: All aspects.
Elevations: Alpine, Treeline.
