A Persistent Weak Layer of faceted (sugary) snow near the ground will continue to be our main avalanche concern for the foreseeable future. This old snow from November will fail and collapse under the newer snow from December. It will get less sensitive but it's going to remain in place and be an issue for the next storms. This situation is nothing to screw around with.
