Riding conditions will be best once the surface crust has softened on sun-affected slopes.
Remain cautious around cornices and on sunny slopes during the warmest parts of the day.
Watch for surface snow becoming wet and heavy as warm temperatures and sun break down the crust. Loose wet avalanches are most likely to initiate on steep slopes, near rock outcrops.
A few cornices up to size 1.5 were triggered with explosives near Whistler on Monday and Tuesday. Several naturally-triggered cornices and loose wet avalanches were also reported. They were small to large (size 1.5 to 2) and initiated on steep sun-affected alpine slopes. We expect this activity to continue while temperatures remain warm and there is strong sunshine.
If you are headed into the backcountry please consider submitting a MIN report!
Strong sunshine and warm temperatures have formed a crust on most surfaces, except on north-facing alpine slopes where the snow may remain loose and dry. Small pockets of wind slab could still linger in those cooler high alpine zones. With daytime warming, the crust will likely soften and melt, improving riding conditions that have been reported as challenging in some areas. However, loose wet avalanches and cornice failures may also become possible during this time. The mid and lower snowpack is dense, well-settled, and currently shows nothing concerning.
