Be diligent in making ongoing assessments. This time of year conditions and hazard will vary greatly from one slope to another and can change quickly throughout the day.

If in doubt choose more conservative terrain.

Avalanche Summary

No new avalanches have been reported in the past few days in the region.

Snowpack Summary

Generally, spring is advancing and the winter snowpack is melting away, at least at lower elevations.

Dry, powder snow may remain at the highest elevations on north-facing terrain, along with the potential for fresh wind and storm slabs. While melt-freeze crusts or moist snow are likely to be found on steep solar slopes and at lower elevations.

Avalanche danger will be closely coupled to warm temperatures, rain, and melting. The more the crust weakens, and the deeper the wetness goes, the greater the hazard from wet loose avalanches.

The mid- and lower-snowpack is generally well-settled. In some areas, the lower snowpack may have a layer of weak facets near the ground.

Terrain and Travel Advice

  • The more the snowpack warms-up and weakens, the more conservative you`ll want to be with your terrain selection.
  • The more the snow feels like a slurpy, the more likely loose wet avalanches will become.
