Weather Forecast

A slight cooling is forecast for the weekend (daytime freezing levels up to 1500m), with mostly overcast skies and scattered flurries/showers.

Snowpack Summary

Ongoing warm temperatures are causing continued settlement of our aging snowpack. A surface crust has been forming overnight and re-softening in the afternoon at treeline and below. Windslabs from the extreme W winds last weekend are now difficult to trigger. Buried up to 1m is a persistent faceting rain crust which has was not been active recently.

Avalanche Summary

A few size 1.0 loose snow avalanches occurred as a result of warming earlier this week.

Confidence

Forecast snowfall amounts are uncertain
