Travel/Terrain Advice

Avoid wind loaded features and solar aspects in the afternoon. Take note of condition changes through elevation bands. Small loose wet avalanches have the potential for high consequences near terrain traps.

Past Weather

20 - 60 cm of new snow with higher totals on the west coast followed by a clearing western flow.

Avalanche Summary

No natural avalanches were observed. Ski cutting produced several small wind slabs on SW-SE terrain at all elevations on Saturday with crowns of 20 -40 cm deep sliding on the December inversion crust.
