Observations remain limited in this region. If you head into the backcountry, please consider sharing your observations to the Mountain Information Network (MIN)!n the alpine and treeline elevations.
Snowpack Summary
New snow will likely fall on surface hoar in sheltered locations and surface facets. 10 to 30 cm of old snow overlies a hard melt-freeze crust up to 1600 m and isolated pockets of surface hoar crystals in wind-sheltered openings at treeline and above.
There are currently no deeper layers of concern.
