Avalanche Forecast
Regions: Coquihalla, Manning.
Fresh snow is accumulating over unstable surfaces, creating dangerous avalanche conditions. Avoid avalanche terrain during periods of rapid loading by new snow and wind.
Confidence
Moderate
Avalanche Summary
No recent avalanches have been reported. We expect avalanches on Friday were small but easily triggered by riders. Avalanche size and sensitivity will likely increase as snowfall intensifies overnight and into Saturday.
Snowpack Summary
New snow is accumulating. By late Saturday afternoon, storm totals are expected to reach 30 to 50 cm, accompanied by moderate southwesterly winds at ridgetops. The new snow is not expected to bond well to underlying surfaces including a hard crust, facets and/or surface hoar.
The mid and lower snowpack is well-settled and dense with no layers of concern.
