Lo esencial

Touchy windslabs and winloaded open areas are best avoided for a few days. Even open areas below treeline are being affected.

    Wind slabs and wind effect will continue to be a problem.

  • Persistent Slabs

    As the new snow increases the load over the March 15 crust on solar aspects we may start to see avalanche activity on this layer. If the facets below the crust also fail, larger propagations will be possible.

Weather Forecast

Temperatures will remain below freezing with moderate to strong west winds and light snow. More precipitation is expected Friday.

Snowpack Summary

Moderate to strong SW winds are creating wind slabs in alpine and treeline areas and beginning to overload cornices. 10-20 cm of recent snow sits over a melt freeze crust on solar aspects with some facets at the crust interface. In shallow snowpack areas the basal facets remain quite weak and may be susceptible to triggering with large loads.

Avalanche Summary

A skier accidental in the Sheol Valley indicates the need for continued vigilance. Poor visibility limited observations today.
