A slight potential remains to trigger avalanches involving buried weak layers. If triggered, these slabs could release as pockets slab with depths up to 18 inches. Pieces of avalanche terrain that could have preserved buried surface hoar are places of concern. These areas are most likely to be found in north facing terrain around an elevation of 8000 - 9500 feet. The chance to trigger an avalanche has decreased but since it can not been ruled out, maintaining standard travel protocols such as having the proper gear, only exposing one person at a time to steep terrain and watching out for your partner(s) when exposed is essential.
Older and deeper weak layers are not thought to be a current avalanche concern and will continue to be monitored.
