Avalanche Summary
There have been no recent reports of avalanches in the region. Avalanche activity is expected to increase with warming to mountain top on Tuesday.
If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).
Snowpack Summary
The surface snow will likely become wet due to warm temperatures and rising freezing levels to mountain top.
In the alpine, new snow from the weekend (we suspect up to 30 cm) sits over moist snow. Elsewhere, 10-15 cm sits above a firm rain crust. Below the crust is a rain-soaked snowpack.
Snow depths at treeline vary across the region from 65 cm to 150 cm.
