The general avalanche hazard is CONSIDERABLE. Loose new snow lies upon dense wind slabs with 
depths up to two feet. These slabs lie upon hard crusts and firm snow and could be easily 
triggered today by skiers and riders in steep wind loaded avalanche terrain. Cautious routefinding 
and conservative decision making is recommended.
