We have not received any nsow in the last 6 days.

We have had constant winds from 20-80 mph during that times.

There has been a great deal of scouring and also wind loading.

Spatial variability remains very high. Snow conditions will vary greatly from place to place.

Natural Avalanches are becoming less and less of a concern the longer this wind condition exists. The slabs in place are bonding and becoming harder and there is less loose snow available for transport to trigger the slide naturally.

The ability for human triggered avalanches still exists. There are still pockets of windloaded slab that could be skier triggered.

Avalanche sizes are not expected to be large should they occur.

Danger levels are Moderate at this time.
