Observers yesterday found that the snowpack structure remains poor in this zone. The reported collapses are a sure sign that the weak layers deep in the snowpack continue to be a concern. The overlying slab is gaining strength by the day but triggering a slab up to three feet thick remains possible, especially on windloaded aspects. Very steep slopes, especially those with signs of wind loading, will be of most concern during the heat of the day.

The recently triggered avalanche on Barber's Point. This avalanche failed on weak snow formed in November.
