Avalanche Forecast

Several skier triggered size 1 wind slab avalanches were reported on northwesterly aspects in the alpine near Whistler on Tuesday.

Two cornice triggered size 2-2.5 wind slab avalanches were reported on a northwest aspect at 1800 m in the Brandywine zone on Monday. One of them hit the Chocolate Bowl access trail. Another size 2 cornice fall was reported in the region on Wednesday but it is unknown if it pulled a slab on the slope below.

A new sun crust exists on the surface on solar aspects. 10-15 cm of recent snow and strong southeasterly wind continue to form wind slabs on lee aspects at treeline and above. These slabs are sitting on either hard surfaces or small facets. The above mentioned wind has also formed large cornices.

A couple crusts with facets sitting above them can be found at treeline and above down 60-180 cm.

The remainder of the mid and lower snowpack is well-settled and strong.
