Expect forecast new snow to take time to bond to a well established hard crust.

Carefully consider your terrain choices prior to committing to steep avalanche terrain, especially those with with evidence of wind transport and loading.




Avalanche Summary

No new avalanches were reported in the region on Monday. Backcountry users will likely see evidence of a small wet loose avalanche cycle from recent rain and solar input below treeline.

If you head out in the backcountry, let us know what you are seeing by submitting a report to the Mountain Information Network.

Snowpack Summary

In terrain above 1600 m up to 10 cm of preserved and wind affected dry snow is likely to exist. An established melt freeze crust can be found at elevations 1600 m and below, expect the new forecast snowfall to take a little time to bond to this old surface. At all elevations the mid and lower snowpack has a number of old melt freeze crusts that are unreactive and overall presents as consolidated, well settled and strong.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Closely monitor how the new snow is bonding to the crust.


Storm Slabs

An icon showing Storm Slabs

Winds slabs are expected to form and be present on all aspects just below ridgetops and areas that transition into convex features.

Aspects: All aspects.

Elevations: Alpine, Treeline.



Expected Size

1 - 2

Loose Wet

An icon showing Loose Wet

The upper snowpack continues to adjust to the recent spring-like weather. As temperatures cool and clouds obscure the sun, expect small loose wet avalanches to continue to only be reactive at lower below tree line elevation terrain.

Aspects: All aspects.

Elevations: Below Treeline.



Expected Size

1 - 1.5
