Travel and Terrain Advice
Watch out for storm slabs on steep slopes at higher elevations with increased snowfall. There are exposed "terrain traps" such as deep gullies, cliffs, rocks, and standing timber that can increase damage even if the size of the avalanche that occurs is small. In lower elevations, exposed bushes make it difficult to ski. Care must also be taken to avoid falling into gully. Solar radiation is expected to be present during the day. Be aware of the possibility of a wet snow avalanche loose snow avalanche from large steep slopes to the south.
