Watch for changing conditions over the day. Fresh snow and wind will build wind slabs at higher elevations.




Avalanche Summary

Operators report chunks of cornice falling during recent warm and sunny weather, they have not entrained snow on the slope below to trigger an avalanche but remain hazardous on their own.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

Light accumulations of storm snow will form deeper deposits on north and east facing slopes at treeline and above. New snow will sit over previous wind affected surfaces at higher elevations on shaded aspects, faceted snow and surface hoar in sheltered areas, and over a melt freeze crust on south facing slopes and at low elevations.

The mid-snowpack is generally well-settled. The lower snowpack includes a layer of weak sugary crystals near the ground. This layer has not produced recent avalanche activity in this area, but professionals are still watching for signs of it becoming active again. Thin snowpack areas (like rocky start zones) should still be avoided as weak layers sit closer to the surface here.

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
