Points saillants

Snow continues to build up on a layer of surface hoar, creating TOUCHY avalanche conditions.

If you experience rain on the new snow, expect the danger to rapidly jump to HIGH.

    New snow is burying a widespread surface hoar layer, creating touchy avalanche conditions. Expect hazard to increase as more snow accumulates over the day.

Confidence

Moderate

  • We are uncertain about forecast precipitation amounts.

Avalanche Summary

No new avalanches have been reported from this area yet, but we anticipate a significant natural cycle will occur as the storm snow accumulates.

If you are heading into the backcountry, please consider sharing your observations with the Mountain Information Network.

Snowpack Summary

New snow falls on a widespread layer of surface hoar ranging from 30 mm below treeline to 5 mm in the alpine.

A crust from early February is down 20 to 50 cm and in most areas appears to be well bonded.

The remainder of the snowpack is well settled. The snowpack depth at treeline ranges from 85 to 130 cm, and there is still very little snow below treeline.

While new snow has improved riding conditions, access is still a challenge, with new snow on bare rock/ground at low elevations.

Terrain and Travel Advice

  • Storm slab size and sensitivity to triggering will likely increase through the day.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • Surface hoar distribution is highly variable. Avoid generalizing your observations.
  • Think carefully about your exit plan from the backcountry because avalanche danger is expected to increase throughout the day.
