Avalanche Summary
No new avalanches were reported on Monday. Forecast precipitation amounts vary, but new storm slabs and loose dry avalanches may occur at upper elevations. Loose wet avalanches are likely at lower elevations.
Snowpack Summary
A mix of rain and snow will fall on a variety of old snow surfaces including crusts and moist snow at lower elevations. In high alpine areas like Sky Pilot and the Chehalis Range the more recent (saturated) snow has refrozen into a solid crust which means that the forecast snow will likely have a poor bond to the crust. At lower elevations rain amounts will saturate the snow surfaces further.The mid and lower snowpack are well consolidated with no significant layers of concern.
