In sintesi

Avalanche conditions continue to be dangerous. Widespread instability exists as slabs of cohesive snow lie over persistent weak snow near the base of the snowpack. Cautious route finding and conservative decision making is essential. Avalanches below 7500 feet are unlikely.

    Above 7500, the potential for humans to trigger slab avalanches with depths to four feet poses a serious threat to backcountry users. If triggered these dangerous slabs will fail on a layer of faceted snow near the ground that persists on all aspects. These slabs could be triggered by the weight of a single person. Yesterday an avalanche was reported to have been triggered by a moose in the south fork of Spread Creek area.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Periods of light snow or flurries are possible overnight with mostly clear conditions expected on Thursday. Mountain temperatures should be in the single digits during the day. Northwest winds during the day will be light. The general avalanche hazard will remain Considerable. Although the likelihood of triggering has diminished, the possibility of triggering deep slab avalanches continues upon a layer that is widely distributed on all aspects above 7500 feet. If triggered these will be dangerous large hard slabs. Deep persistent slab avalanches are the most difficult avalanche problem to assess, predict and manage. They can remain unstable for weeks or months.
