Limit your exposure to avalanche terrain as temperatures continue to rise.
If the sun comes out the upper snowpack will quickly lose strength.

Snowpack Summary
Expect surface snow to continue to get wet as temperatures rise and the sun comes out.
Roughly 40 to 50 cm of snow from the past week sits over various old surfaces. In some areas, it is slow to bond due to sugary facets.
Near the bottom of the snowpack, there are a series of crusts and facets that are more prominent in shallow areas.
