Avalanche Summary

Snowpack Summary
Up to 10 cm of new snow may accumulate by Sunday morning. This new snow will be accompanied by moderate to strong southerly winds forming wind slab on north aspects. In sheltered terrain this new snow may overlie soft, faceted snow or surface hoar. In exposed terrain it will overlie a sun crust or wind-affected snow.
A weak layer that was buried at the end of January is down 30 to 80 cm in the snowpack. Depending on where you are, it'll be a combo of different crystals. With crusts on sunny slopes, sugary facets in most places, and surface hoar in sheltered spots.
The mid and lower snowpack is strong and bonded.
