A mix of sun and cloud and generally dry for Tuesday before a weak storm pushes through overnight Tuesday with 10-15 cm expected by Wednesday afternoon, accompanied by moderate to strong southwesterly ridgetop winds. Another dry day is expected for Thursday. Daytime high freezing levels are expected to hover around 1100 m for the forecast period.

Avalanche Summary

No recent avalanche observations reported. If you have been out in the mountains, please submit your observations to the Mountain Information Network (MIN).

Snowpack Summary

Another 25-30 cm brings total snowpack depths to around  150 cm at treeline, and 2 m or more at higher elevations. This new snow continues to build weak storm slabs with particularly deep and touchy wind slabs on leeward slopes in exposed areas. Recent reports suggest that  trail breaking and downhill travel was difficult due to the deep and heavy storm snow.

Problems

Storm Slabs

An icon showing Storm Slabs
Recent storm slabs may be moist or rain soaked at all but the highest elevations, but if you get high enough to find deep drier snow, expect storm slabs to continue to be reactive to light additional loads like a single skier.
The new snow will require several days to settle and stabilize.Be cautious as you transition into wind affected terrain.Be alert to conditions that change with elevation.

Aspects: All aspects.
