    Small pockets of wind slabs have likely formed on northerly aspects at upper elevations during the storm on Tuesday. Cool temperatures may help to preserve these instabilities.

Avalanche Summary

No recent avalanche activity has been reported. Small loose wet avalanches may have occurred Tuesday on steep slopes at lower elevations with moderate rain and wet snow.

Snowpack Summary

At lower elevations, rain has created a moist snow surface. At higher elevations, up to 10 cm of snow has accumulated over a crust or moist snow. Snow surface of high north-facing alpine slopes may still be dry.
