    Recent snow may slide easily over the crust. Slabs will be deepest and most reactive in wind-loaded pockets at upper elevations.

Avalanche Summary

Some small (size 1) natural dry loose and storm slab avalanches, as well as a few skier-triggered size 1.5s were reported on Tuesday and Wednesday.

Snowpack Summary

10 to 20 cm of recent snow has fallen above a widespread crust layer. The crust does not likely exist on north-facing slopes above 2000 m.

Small wind slabs may have formed in the immediate lee of ridges.

A persistent weak layer that plagued the region for the first half of March is now 150 to 250 cm deep and no longer a concern.
