    These deep persistent slabs at tree line and sheltered alpine slopes may be triggered from shallow areas within the snowpack.

Weather Forecast

Snow is forecasted to arrive on Thursday and continue through the weekend, but total snowfall amount is predicted to be less than 10cm. Light winds and seasonal temperatures will continue.

Snowpack Summary

Widespread surface hoar to size 10mm. A strong mid-pack overlies approximately 20-40cm of facets. Isolated wind slabs still exist in open areas at tree line and alpine elevations. The interface between the mid-pack and facets is most susceptible to human triggering from shallow areas.

Avalanche Summary

No new avalanches observed today, but there is evidence of large deep slides in wind loaded features that have released in the last cycle.

Confidence

Wind speed and direction is uncertain on Friday
