Conditions will change with elevation and wind exposure. Reactive slabs remain a concern in wind-loaded features, but sheltered terrain holds great riding conditions.
Wind slabs are most reactive during their formation. Watch for active wind transport, and back off slopes with hollow, drum-like sounding snow.
On Sunday, loose dry natural avalanches were observed up to size 1.5 from steep terrain features. Explosives triggered slab avalanches to size 1.5.
Moving forward, expect slab reactivity in wind-loaded terrain features, with loose sluffing on steep, sheltered slopes.
Up to 15 cm of new snow is expected by Tuesday morning. This falls over 40-60 cm of wind affected, settling snow that is generally bonding well to the crust below.
The mid and lower snowpack is generally well-settled and contains multiple crust layers.
