    New snow and south west winds has formed small wind slabs in leeward terrain features.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.
  • We are uncertain about how the timing or intensity of solar radiation will affect the snowpack.

Avalanche Summary

On Tuesday, avalanche control work conducted south of Hope produced a few small (size 1-1.5) loose dry and slab avalanches with good propagation but not running fast or very far.

If you are heading into the backcountry, consider sharing your observations and posting a MIN.

Snowpack Summary

Up to 35 cm of new has fallen over the past week. As temperature warmed, this new snow has settled and bonded with 50 cm of snow that is above a widespread, thick and hard crust that exists everywhere except the highest alpine terrain.

Steep south facing slopes may be crusty or moist depending on time of day and sun exposure.

The lower snowpack is generally strong and bonded.
