Avalanche Summary

No avalanches were observed or reported today.

Snowpack Summary

20cm of recent snow overlies sun crusts to ridgetop and temperature crusts below 1500m. The mid-pack in this area is generally strong, although the base of the snowpack consists of weak facets in thin areas (<2 m).

Weather Summary

On Friday, cloudy skies and flurries are expected throughout the region. Snowfall amounts are not forecast to be more than 5 cm as precipitation rates will likely increase through the afternoon. Winds at ridgetop are expected to be in the strong range, blowing out of the south west. Freezing levels will reach 2000m-2300m and the alpine high is forecast to hit +2C.

Saturday should see the front move through and flurries will tapering through the day. Temperatures are expected to be slightly cooler, as the forecast alpine high is 0C.
