West Central Montana Avalanche Center: Dangerous avalanche conditions will develop today. Heavy snowfall and sustained winds continue to impact the area and build storm slabs across all elevations and aspects. Natural avalanches are likely, and human triggering is certain. Avalanches can step down to faceted layers at the base and mid snowpack, resulting in large unsurvivable avalanches.
Flathead Avalanche Center: Today you can trigger avalanches that may be dangerous on slopes steeper than about 35 degrees with more than about 8 inches of new and drifted snow. Those conditions won’t be widespread unless the storm arrives earlier than forecast. Shooting cracks, fresh natural avalanches, and whumpfing collapses are all clear signs the party is over and it’s time to head home. Dangerous avalanche conditions will develop tonight as snowfall and winds intensify.
