In sintesi

Low hazard is not no hazard.

Small human-triggered avalanches are still possible in steep terrain where the snow surface remains moist.

    Where the upper snowpack remains moist, loose wet avalanches may be possible to human trigger in steep terrain.

Avalanche Summary

No new avalanches were reported in the region on Thursday.

If you are heading into the backcountry please consider posting your observations to the Mountain Information Network. All of the conditions information and photos are helpful for forecasters.

Snowpack Summary

New snow covers refrozen surfaces at treeline and above. Below the crust, 30 to 50 cm of moist snow overlies a thin sun crust on south aspects and dry snow elsewhere.

With prolonged warm temperatures two weak layers of surface hoar and/or facets overlying a crust have slowly gained strength. While professionals continue to track these layers they have not produced recent avalanche activity and are not a concern at this time.

The lower snowpack is well-settled.

Terrain and Travel Advice

  • Watch for unstable snow on specific terrain features, especially when the snow is moist or wet.
  • A crust on the surface will help bind the snow together, but may make for tough travel conditions.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
