Avalanche Summary

No new avalanches were reported in this region on Monday. However, field observations are currently very limited.

If you go into the backcountry, please consider submitting your observations to the Mountain Information Network.

Snowpack Summary

15 to 30 cm of recent snow and strong southwest wind have formed wind slabs on lee features at treeline and above.

The recent snow overlies a crust on all slopes except true north facing terrain at upper elevations where the previous snow remained dry.

Below treeline is either snow free or has very thin snow coverage. Expect difficult travel at lower elevations.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • Be especially cautious as you transition into wind affected terrain.
  • Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
  • Back off slopes as the surface becomes moist or wet with rising temperatures.
