Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Up to 10 cm of new snow sits atop various surfaces at higher elevations, including firm wind-affected surfaces, hard crusts, and loose powder snow (primarily in sheltered north-facing terrain).

Large, fragile cornices can be found on exposed ridgelines and should be given a wide berth.

Below roughly 1300 m a trace of new snow overlies a widespread melt-freeze crust.

Terrain and Travel Advice

Make observations and assess conditions continually as you travel.
When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
Pay attention to cornices and give them a wide berth when traveling on or below ridges.
Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
