Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

A few storm slabs and several wet loose avalanches were reported on Sunday, up to size 1.5.

Observations are limited; if you are going into the backcountry, please support the forecast by posting a MIN.

Snowpack Summary

Up to 20 cm of new snow falls on a widespread crust from previous warm temperatures and sun up to 2100 m.

A hard crust is buried 30 to 70 cm deep, but may remain exposed in wind-scoured alpine terrain. It extends up to at least 1500 m in the Rockies, and 2000 m in the Cariboos.

Below the crust, the snowpack is strong and well-bonded.
