Points saillants

Avalanches remain possible where dry snow is available to form fresh wind slabs

Watch for areas without a thick crust at or near the surface, buried weak layers may remain reactive

    Persistent weak layers may linger in the upper snowpack. Triggering may still be possible in areas without a thick and supportive surface crust, most likely at upper treeline and alpine elevations.

Confidence

Moderate

  • We are uncertain about how quickly the snowpack will recover and gain strength.
  • We are uncertain due to a limited number of field observations.

Avalanche Summary

On Saturday, small loose wet avalanches were observed. The previous rain and warm temperatures produced a widespread wet avalanche cycle to size 3.

If you are heading into the backcountry, please consider sharing conditions via the MIN.

Snowpack Summary

A widespread, developing melt-freeze crust exists, extending to mountain top in most areas. Around 15 cm of new snow can be found at upper elevations, redistributed by southwest winds.

Below this, 30 to 50 cm of wet snow sits above a crust (1 to 10 cm thick). Various persistent weak layers may still exist in the top 120 cm of the snowpack - these remain a concern at higher elevations where a supportive surface crust does not exist.

In shallow snowpack areas, depth hoar (large facets) can be found near the bottom of the snowpack.

Terrain and Travel Advice

  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
