You could trigger a large and dangerous avalanche. You will need to be on or near a steep slope at upper elevations. Common trigger points include rock outcroppings, steep rollovers, below ridges, and cliff bands. Use caution on steeper slopes where the snow surface transitions from soft to stiff or in places with a smooth, rounded appearance. You can find safer riding options below treeline or on low-angled, wind-sheltered slopes without steep overhead hazards.
A large winter storm begins to impact the Southern Mountains on Monday lasting through Wednesday. Expect the avalanche danger to rise by Wednesday as heavy snow and strong winds build dangerous slabs of snow and overwhelm weak snow layers.
