Sheltered, north facing terrain at upper elevations is likely to provide the best riding, but avoid exposure to slopes with large cornices overhead.
Lingering wind slabs may remain reactive to human triggers on steep, convex slopes below ridgetops.
Avoid exposure to cornices overhead when the sun is out.
THURSDAY NIGHT: Clear / Light, west ridgetop wind / alpine low temperature -14 / Freezing level valley bottom.
FRIDAY: Sunny / Light, west ridgetop wind / alpine high temperature 1 / Freezing level 1700 m.
SATURDAY: Sunny / Light, southwest ridgetop wind / alpine high temperature 4 / Freezing level rapidly rising to 2500 m. and staying elevated overnight.
SUNDAY: Mix of sun and cloud / Moderate, southwest ridgetop wind / alpine high temperature 5 / Freezing level 2500 m.
On Wednesday, there was report of a skier triggered size 1.5 wind slab avalanche failing on facets on a steep north aspect in the alpine.
On Tuesday, there was a report of naturally triggered size 2 cornice and a couple skier triggered slab avalanches up to size 1.5 on north and east aspects in the alpine.
Dry soft snow can be found on shaded aspects above around 1500 m. On south-facing slopes and at lower elevations expect crusty snow in the morning and soft, moist snow in the afternoon. Winds have slackened off as of late, but recent wind slabs and cornices still pose a hazard close to steep ridgelines.
The lower snowpack has strengthened over the past week as previous persistent weak layers have become unreactive. The main layers that we had been tracking were a layer of facets that was buried in mid-February (50-100 cm deep) and a layer of surface hoar and/or a crust that was buried in late January (80-120 cm deep).
