Glacier.

With rising freezing levels and more rain in the forecast expect moist snow well into the alpine. The moist surface will be easily triggered, and avalanches will gain mass on steep slopes.

Summary

Problems

Loose Wet

The rain has saturated and weakened the snowpack. Avalanches are starting small but gain mass on steep terrain running long distances into below treeline areas. Expect avalanche activity to increase during periods of heavy rain.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood

Possible - Likely

Expected Size

1 - 3

Snow started falling at Mt Fidelity on Oct 16. Since then the station has received 130cm of snow which has settled to an HS of 62cm. If you manage to get above freezing level (~2200m?) expect to find storm snow and windslab instabilites.

Aspects: All aspects.

Elevations: Alpine.
