Avalanche Summary

No recent avalanche activity has been reported.

Snowpack Summary

A widespread crust of varying thickness exists at all elevations. As much as 10 cm of dry snow may sit atop the crust in some areas.

A weak layer consisting of a crust and facets may persist in areas, down roughly 30 to 80 cm from the surface. A second crust exists down roughly 100 cm or more.

The lower snowpack is characterized by weak basal facets in many areas.

Weather Summary

Sunday Night

Mostly cloudy with 0 to 5 cm of snow, northeast alpine winds 0 to 20 km/h, treeline temperature -6 °C.

Monday

Mostly cloudy with trace snow amounts, southeast alpine winds 0 to 20 km/h, treeline temperature -6 °C.

Tuesday

Mostly cloudy with 0 to 5 cm of snow, southwest alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Wednesday

Mostly cloudy with 0 to 3 cm of snow, south alpine winds 10 to 30 km/h, treeline temperature -5 °C.

Terrain and Travel Advice

  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Avalanche hazard may have improved, but be mindful that deep instabilities are still present.

Avalanche Problems

Wind Slabs

In some areas, recent snow has been redistributed into thin wind slabs over a hard crust.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 1 - 1.5

Persistent Slabs

In areas where the surface crust isn't present or doesn't support your weight, weak layers deeper in the snowpack could still be human-triggered.

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 3
