Confidence

Poor - Due to limited field observations

Weather Forecast

A ridge of high pressure builds over the province bringing a mix of sun and cloud to inland sections of the Northwest on Friday, Saturday, and Sunday. Winds should ease to light-moderate from the NW and the freezing level should remain at or near valley bottom.

Avalanche Summary

No new observations. Wind slabs and storm snow instabilities will remain susceptible to human triggering for at least the next couple days.

Snowpack Summary

New hard and soft wind slabs are likely well into treeline due to very strong W-SW winds on Thursday. The average snowpack depth at treeline is over 200cm. The mid and lower snowpack are generally quite strong. Watch for clues of instability like whumpfs or shooting cracks, and if observed back off any steeper objectives.
