Avalanche Summary

No new avalanches have been reported in the region. Please submit your observations to the Mountain Information Network.

Snowpack Summary

In most places a combination of rain and/or warm temperatures has likely made the surface snow moist or wet. High elevation alpine and especially north aspects may still hold dry snow. If there has been a good overnight freeze, you may find a supportive crust on the surface. The mid and lower snowpack pack are likely a mixture of moist snow and crusts. Below treeline the snowpack is mostly melting away.

Problems

Wind Slabs

An icon showing Wind Slabs

Likelihood

Possible

Expected Size

1 - 1.5

New snow possibly accumulating overnight Friday through the day Saturday combined with primarily southwest winds is likely to create fresh wind slabs in the lee of terrain features.

  • Be cautious as you transition into wind affected terrain.
  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects:

North, North East, East, South East.

Elevations:

Alpine.

Loose Wet

An icon showing Loose Wet

Likelihood

Possible

Expected Size

1 - 1.5

Rain at lower elevations will keep the surface snow moist or wet and promote sluffing in steep terrain.

  • A moist/wet snow surface, pinwheeling, and natural avalanches all indicate increased instability.

Aspects:

All aspects.

Elevations:

Treeline, Below Treeline.
