Avalanche Forecast

size 1 wet loose avalanches Below treeline were reported on Wednesday. We suspect more avalanche activity took place but observations are limited in this region.

If you are going out in the backcountry, please consider sharing your observations to the Mountain Information Network (MIN)

By early morning on the 20th another 5 to 15 mm of precipitation could have fallen. Below treeline the majority of this precipitation will fall as rain, saturating the upper snowpack. In the alpine most of this precipitation will fall as snow. This new snow will be  accompanied by southerly winds likely forming deep deposits on northerly aspects.

In the alpine, an estimated 50 to 90 cm of snow sits above a thin crust. We are not concerned about this layer in this region

Snow depths at treeline vary across the region. Around 140 cm is reported in the Coquihalla and 85 cm near Manning Park.
