In sintesi

Incoming snowfall may not be enough to cover up those early-season hazards.

Monitor how snow that has been transported by the wind is bonding to old surfaces.

    Watch for patches of soft wind slab in exposed lees. Investigate the bond between wind slabs and underlying surfaces before committing.

Snowpack Summary

Unconsolidated snow, 20 to 30 cm, overlies a series of crusts in most areas. In exposed areas, it covers old wind slabs.

At treeline, the height of snow ranges from approximately 50 to 90 cm. Below this elevation, snow height decreases drastically.

The snowpack at all elevations is very shallow and contains many potential hazards just beneath the surface.

Read the new Forecaster's Blog for more on the early-season snowpack.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the old surface.
  • Expect shallow snow cover that barely covers ground roughness.
  • Avalanche danger is often elevated in alpine gullies where snow has accumulated.
