Snowpack Summary
Snowfall was sporadic or failed to materialize with the last storm system. Since Sunday, areas further north in the region may have accumulated 5-15 cm of snow. In these areas, southwesterly winds likely transported the available snow into wind slabs on lee features in the alpine. In isolated areas, these small slabs are likely sitting on a mix of sugary faceted snow, and feathery surface hoar crystals, and hard wind-affected snow that may be reactive to human triggering.
Snowpack depths are 50-100 cm in alpine areas around Smithers, with depths diminishing rapidly below 1500 m.
Problems
Wind Slabs
Areas in the region that received 5-15 cm of snow since Sunday may have isolated pockets of wind slab could still be reactive to human triggering. Watch for lee features in the alpine with denser and deeper drifts.
Aspects: North, North East, East, South East, North West.
