Avalanche Summary
Our limited field data suggests a natural avalanche cycle occurred in the past few days as rain and warm temperatures infiltrated the region.
Please consider submitting your observations to the Mountain Information Network.
Snowpack Summary
New snow accumulates atop a crust or moist snow from rain in the past few days. Strong winds will redistribute new snow and create heavily wind-affected surfaces.
The remainder of the snowpack is strong, with various hard layers and crusts.
