    Continued potential for loose wet avalanches exists where the surface has been saturated with rain and at lower elevations where new snow is moist.

Confidence

Low - Due to the number of field observations

Snowpack Summary

Although recent heavy rain has saturated the upper snowpack throughout the region, a fresh cover of wind affected new snow has been forming storm slabs at all elevations in the south of the region. While limited field observations have led to uncertainty in the composition of the mid and lower snowpack, moist snow is expected to be dominant throughout the snowpack.
