Avoid wind-loaded terrain at upper elevation.
As much as 50 cm of new snow arrived in the past 24 hours, accompanied by strong southwest winds. Where dry snow exists, wind slabs will be reactive to rider triggering.
No new avalanches have been reported. Observations have been limited with no field team in the area last week.
If you head out, please consider posting your observations to the Mountain Information Network.
Yesterday's storm has left a rain-soaked snow surface at lower elevations and 10 to 50 cm of new snow in the alpine, redistributed into wind slabs by strong southwest winds.
50 to 70 cm of snow may be overlying a layer of surface hoar in sheltered areas at and below tree line. There is uncertainty with its distribution and reactivity at this time.
The remaining snowpack has no other layers of concern.
Snowpack depths at treeline range from 95 to 250 cm, and there is still very little snow below treeline.
