Lo esencial

Forecasted extreme winds in the high alpine will increase wind slab development.

    Steep cross or lee winded slopes with steep convex roles are likely slab trigger zones. In the alpine the snowpack depth is highly variable. At treeline travel is good and the snowpack supportive.

    The deep persistent slab can be triggered most easily where the snowpack is less than 100cm and wind stiffened. Snow depths are highly variable in the alpine. At and below 1,600m a 5cm rain crust down 15cm is adding increased stability.
