On Wednesday, three natural storm slab avalanches were reported size 1.5-2 on northeast aspects at 1850 m.

On Monday, natural storm slabs up to size 1.5 were observed in steep alpine terrain below cliffy headwalls in the Lizard range. One was triggered by a cornice fall.

Thin surface crusts may be found on a variety of aspects and elevations. Wind loaded pockets are forming in lee features in the alpine. After over 1 m of steady snowfall last week, the stout upper snowpack continues to settle in the mild temperatures.

Several crust layers exist in the mid snowpack as a result of previous warming and rain events. These have not been identified as bed surfaces or failure planes in recent avalanche activity.

The bottom 10-20 cm of the snowpack consists of faceted snow and decomposing crusts. Although inherently weak, this basal layer has not been an active avalanche problem in our region since 2019.

• Carefully evaluate bigger terrain features on an individual basis before committing to them.
• Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
• Use caution above cliffs and terrain traps where even small avalanches may have severe consequences.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
