    Continue to pay attention to the weak basal facet layer in areas where the snowpack is shallow (<2 m) such as moraines or wind-scoured areas, or in places with large triggers like cornices that could impact the slope.

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.
