Avalanche Summary

No new avalanches were reported by 4 pm on Sunday.

On Saturday, several human-triggered size 1 storm slab avalanches were reported on north and west facing slopes below ridgecrests.

If you are headed to the backcountry, please consider sharing your photos and observations from your day on the Mountain Information Network.

Snowpack Summary

30 to 55 centimeters of storm snow blankets the region. Ongoing moderate southwest winds have redistributed storm snow into deep pockets on lee slopes at the ridgeline. Storm snow covers a thick a crust except on high north facing terrain, where new snow buries 5 to 20 cm of dense snow overlying a crust from earlier in March.

The mid and lower snowpack is strong and dense.

Terrain and Travel Advice

  • Avoid freshly wind-loaded terrain features.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.

Avalanche Problems

Storm Slabs

Up to 55 cm of storm snow and moderate winds have built reactive storm slabs at all elevations. Back off if you encounter signs of instability like whumpfing, shooting cracks or recent avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 1 - 2.5
