Avalanche Summary
There have been no recent reports of avalanches in the region. Small and isolated wet loose avalanches may be seen in steeper terrain with sunshine and warming.
If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).
Snowpack Summary
The surface snow is likely wet due to warm temperatures and rising freezing levels to mountain top.
North through east facing slopes in the alpine may have new surface hoar development and hold dryer snow (10 to 30 cm) which sits over moist snow. At treeline, 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.
