Avalanche Summary

You could trigger an avalanche in the new storm snow. The more dangerous areas are where new snow has settled into a connected slab on steep alpine slopes. Where a slab has not formed, loose avalanches could sweep you off your feet and take you for a dangerous ride, particularly in steep consequential terrain. As the sun pops, anticipate small natural loose activity on many slopes.
