    The biggest concern right now are isolated wind slabs in lee alpine terrain. Although no recent natural activity has been reported these wind slabs may be triggered by skiers or climbers.

Weather Forecast

Light snow with minimal accumulations are forecast through the end of the week. A slight warming trend is expected starting on Wednesday and moderate to strong west winds are expected on Wednesday and Thursday. If these winds arrive the avalanche hazard will  increase.

Snowpack Summary

There is 50-70 cm of snow at tree line which is generally weak and facetted, however in some areas the mid-pack is supportive enough to allow some tentative turns. Some fresh wind slabs exist in lee alpine terrain which may be reactive to skier triggering. The October crust is 10-20 cm from ground and producing mod-hard results with comp. test.

Avalanche Summary

No new avalanche activity observed in the last several days.

Confidence

Wind speed and direction is uncertain on Wednesday
