POWELL RIVER, B.C. – B.C. is not in the clear just yet.

Avalanche threat is high in alpine and treeline elevations. According to Avalanche Canada, there is also considerable threat to terrains below the treeline.

Heavy snowfall, high winds, and freezing temperatures are producing storm slabs. Storm slab avalanches have the potential to grow to size three.

Size three avalanches are big enough to damage and bury cars, damage trucks, as well as bury small buildings and break trees.

Storm slab avalanches are caused by a cohesive slab of new snow on top of old snow. It may look soft, but is quite powerful.

Drivers are advised to travel through simple terrains and to seek out alternative routes other than high and alpine terrains.
