    Use caution in wind affected areas. New snow and strong westerly winds have likely formed wind slabs in lee terrain features at upper elevations.

Confidence

Moderate - Uncertainty is due to the limited number of field observations.

Weather Forecast

The notable feature in the weather forecast for the next few days is very high winds at upper elevations.

Avalanche Summary

There have been no recent avalanches reported in the region. If you are getting out into the mountains, let us know what you see by posting to the Mountain Information Network!

Snowpack Summary

Approximately 10 cm of new snow sits on a mix of sugary faceted snow, and hard wind affected snow. The new snow is likely being formed into wind slabs by strong westerly winds. The total snowpack depth is between 50-100 cm in the alpine, and tapers rapidly at lower elevations. Two crusts have been reported in the middle of the snowpack. There is uncertainty as to how well the snow is bonding to these crusts.
