Buried surface hoar persists in the snowpack six to eighteen inches below the old snow surface. In isolated areas, particularly in colder protected areas, skiers and riders might still be able to trigger hard slabs failing on this weak layer. These slabs will be more sensitive in the afternoon as they are weakened by warming.
