Sorry, but this is going to sound like a broken record. Weak sugary faceted snow near the base of our snowpack is going to remain a serious concern for some time to come. It's called a Persistent Weak Layer because it persists and causes problems for long periods of time. In some areas I've seen some improvement of sugary snow where it's gained some strength but we're far from being out of the woods. Collapsing of the snowpack continues. We really need a few more feet of snow to help press down on the old weak snow and make the snow grains bond.
Chances for triggering an avalanche become less each day but the large size stays the same.
