Avalanche Summary
There have been no recent avalanche reports in the region.
Increasing snowfall mixed with rain and strong southwest wind are certain to induce a natural avalanche cycle.
If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).
Snowpack Summary
New snow mixed with rain will bury a firm crust at treeline and will become increasingly unstable as the new snow rapidly gets deeper. North through east-facing slopes in the alpine may have buried surface hoar which sits over moist snow.
Snow depths at treeline vary across the region from 65 cm to 150 cm.
