Avalanche Summary
Several MINs from the Coquihalla area on Sunday reported wind-affected snow, shooting cracks, and several small skier-triggered wind slabs.
Snowpack Summary
A surface crust may form Monday night after warm temperatures. This is likely on all aspects except northerly aspects in the alpine.
Recent snow has seen moderate redistribution in wind-exposed terrain. Good snow quality has been reported in wind-sheltered areas.
A substantial crust up to 30 cm thick sits 50 to 100 cm deep, well-bonded to surrounding snow. The mid and lower snowpack is generally well consolidated, with several well-bonded crusts scattered throughout.
Treeline snow depths range from roughly 150 to 220 cm around the Coquihalla and 100 to 150 cm around Manning Park.
