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
Loose moist snow in motion released a wet slab on a North aspect of Mt. Hosmer. Loose wet or moist snow is expected to continue to release naturally from steep terrain or rocky areas at lower elevations.
Snowpack Summary
Overnight freezing has consolidated previously loose wet snow at treeline and above. Some new wind slabs may have developed during periods of strong Easterly winds combined with new snow. The surface crust is expected to break down during the day and then re-freeze tonight. Moist or wet snow below treeline is not expected to have much of a recovery, and may continue to be isothermal and weak.
