Avalanche Activity

Small amounts of fresh snow blanket small snowdrift accumulations

A single winter sports enthusiast can trigger small slab avalanches in some places, particularly in ridgeline terrain and in wind-loaded gullies and bowls. If releases then sweep away deeper weak layers of the snowpack, the avalanche can in isolated cases grow to medium size. Danger zones are impossible to spot. Whumpf noises and fractures forming on the surface are alarm signals.

Snowpack Structure

A small amount of fresh snow blankets older, generally somewhat stabilized snowdrift accumulations. The often lie deposited on loosely-packed snow or surface hoar or a melt-freeze encrusted surface. On steep slopes, unfavorable ground-level and intermediate layers inside the old snowpack persist in many places.

Weather Forecast

Friday will be heavily clouded, with limited visibility, intermittent light-to-moderate snowfall. Temperature at 2000m: -2 degrees; at 3000m: -7 degrees. Moderate westerly winds at high altitudes.

Tendency

Unfavorable snow base and intermediate layers will persist.
