Avalanche problem #1 : Storm Slab
What Elevation? Which Slopes? Chances of Avalanches? Expected Size?

The amount of snow forecasted for Sunday is highly greater in the north area of the park. There will be a bug difference for the triggered probability depending where you are. In the highly risked area, skiers or snowboarder triggering will be really likely. The high amount of obstacles still there or right below the surface will increase the consequences of an avalanche.
