    Loose wet snow slides may release naturally from steep terrain at treeline and below. Wet slides in motion may gain a lot of mass as they scour isothermal snowpacks down to the ground.

Confidence

Fair - Freezing levels are uncertain for the entire period

Weather Forecast

A ridge of High pressure is expected to develop over the interior regions by Monday evening. The high pressure is expected to continue to cause clearing skies and light winds on Tuesday. The next Pacific disturbance is forecast to make its way into the interior on Wednesday, bringing light precipitation, rising freezing levels and strong gusty winds. Unsettled weather with cloud and periods of convective showers are forecast for Thursday.

Avalanche Summary

No new avalanches reported. Expect loose wet snow releases from steep terrain at treeline and below. Pockets of wind slab may be triggered by skiers or riders at higher elevations.

Snowpack Summary

30 cms of new snow has fallen at 1800 metres elevation. Moderate East-Southeast winds have transported snow into wind slabs at alpine elevations, and scoured down to a hard crust on Easterly aspects. The snowpack continues to be moist below the crust.
