Snowpack Discussion
Since Saturday, 25 to 45 cm of snow has accumulated at upper elevations, while lower elevations saw mostly rain.
A further 15 to 30 cm of snow with rain at lower elevations is expected overnight and through Thursday, accompanied by strong to extreme southerly ridgetop winds. This will likely build cornices and form deeper more reactive slabs on lee northerly slopes while scouring windward southerly slopes.
The highest precipitation amounts are forecast for the western parts of the region, with lower amounts for the Allison Pass area.
Below treeline, a crust or moist snow will likely be observed on the surface.
Snow depths at treeline range from 140 cm in the Coquihalla to 85 cm near Manning Park.
Avalanche Activity
We are aware of an avalanche incident occurring near Coquihalla Summit on Wednesday. At this time, no further details are available.
A small rider-triggered avalanche occurred near Needle Peak on Monday. See photo below.
Looking ahead, we expect to see more natural and human-triggered avalanches occurring throughout the storm cycle.
