Tetons

A spring storm has created dangerous avalanche conditions above an elevation of 8,500 feet. Over the past several days the mountains have received about 20 inches of new snow with over two inches of moisture. Snowfall totals since midweek are nearly 30 inches with over three inches of moisture. At the higher elevations this new snow lies upon firm old snow surfaces. Slab avalanches up to 30 inches deep formed by west winds and wet lose avalanches that entrain significant volumes of new snow are possible on steep slopes and in cliff areas. Warming temperatures and periods of sunshine will increase the hazard as the day progresses and may trigger natural avalanche activity. Human triggered slab avalanches and loose snow avalanches are likely in steep terrain. Knowledge of avalanche terrain and excellant route finding skills combined with a conservative approach are essential for safe travel in avalanche terrain today.
