Summary

Weather Forecast

A weak system tracking in from the west will bring light snowfall to this region overnite and Friday. Accumulations by Saturday may be up to 20 cm. Light to moderate westerly winds are forecasted through to Saturday.

Snowpack Summary

The main issue currently is the Dec.18 layer which is down 20-30 cm and sits on a crust/surface hoar combination at elevations below 2100 meters and on a facet/surface hoar combination at higher elevations. The surface hoar appears to be more prevalent below 2100 meters. Easy to mod shears found on this interface. Wind effect found in the alpine.

Avalanche Summary

No new avalanches have been observed or reported. A large settlement was observed on the Dec 18 surface hoar down 30 cm by a group en route to Isolated Col.
