Avalanche Summary
Recent avalanche activity includes loose moist sluffs to size 2.0 from daytime warming as well as isolated natural cornice releases to size 2.0. Thin windslabs up to size 1.5 have also been seen.
Snowpack Summary
The recent warm, clear weather has left us with an aggressive melt freeze crust on solar aspects well into the alpine while shady, dead north slopes have grown some small surface hoar and remain powdery. Minor accumulations of new snow now overlie these surfaces. Increasing southerly winds are beginning to build new windslabs in lee locations at ridgecrest. Cornices loom in the alpine and continue to grow under the current conditions. The vast amount of recent storm snow continues to settle and bond while deeper in the snowpack the persistent weakness from mid February remain a lingering concern due to continued sudden planar test results.
