Over the last 3 days there have been numerous reports of natural storm slab activity up to size 2.5 on northeast aspects in the alpine. Explosive control work has been up to size 2, as well as reports of skier triggered size 1s.

New snow and moderate southwest winds have formed wind slabs in lee features in the alpine. A temperature crust formed Friday at least as high as 1600 m.

The stout upper snowpack continues to settle in 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.

• Be alert to conditions that change with elevation, aspect and exposure to wind.
• Be careful as you transition into wind affected terrain.
• Even brief periods of direct sun could produce natural avalanches.
• Pay attention to cornices and give them a wide berth when traveling on or below ridges.
• When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
