CAUTION! We are entering the first period this spring with freezing levels above 3500m and no or limited overnight freeze. This is a ALL MELT, NO FREEZE scenario.

We are also expecting new snow or rain on Saturday night that could increase the avalanche hazard.

Limit your exposure to avalanche terrain.

Confidence

Moderate

Avalanche Summary

No recent observations of large avalanches

Snowpack Summary

Without a good overnight freeze the snowpack is slush to treeline. With a good freeze there are surface crusts on south aspects to mountain top and on north aspect to 2600m. On sheltered northerly slopes above 2600m, soft snow exists and the snowpack remains susceptible to triggering deeper, unstable layers.

Terrain and Travel Advice

  • Back off slopes as the surface becomes moist or wet with rising temperatures.
  • Loose avalanches may step down to deeper layers, resulting in larger avalanches.
  • Travel early on sun-exposed slopes before cornices weaken with daytime warming.

Avalanche Problems

Loose Wet

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Very Likely

Expected Size: 1 - 2

Deep Persistent Slabs

This is combination of midseason persistent weak layers and the weak facets & depth hoar at the bottom of the snowpack.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 2 - 4

Cornices

Aspects: North, North East, East, South East, South.

Elevations: Alpine.

Likelihood: Possible

Expected Size: 2 - 3
