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.
