A series of storms are forecast over the coming days.
Storm slabs will continue building at upper elevations overnight and into Tuesday
Storm slabs have formed at treeline and above. Expect deeper and more reactive deposits on lee slopes.
Wet loose avalanches remain possible with warm temperatures and rain at lower elevations.
Observations have been limited in this region. We expect avalanche activity will continue, especially in areas above 1200 m where new precipitation is forecast to fall as snow and not rain.
If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN).
An additional 20 to 40 cm of snow fell at upper elevations overnight Monday, bringing the total since Saturday to as much as 80 cm in alpine areas. Most of this precipitation fell as rain at treeline and below. By the end of Tuesday, another 10 to 30 cm of snow is expected, with moderate to heavy rain below 1200 m.
In the alpine, strong winds are expected to form deeper storm slabs on lee northeast through northwest-facing slopes.
Below treeline, expect a rain-saturated snowpack or lack of snow at lower elevations.
