Avalanche Forecast

Fair - Timing, track, or intensity of incoming weather system is uncertain

A warm front will bring precipitation to the north coast on Wednesday night and Thursday. Unsettled conditions are expected for Friday before the next system reaches the coast on Saturday.Wednesday Night: Precipitation: 5-10mm, freezing level: 1300m, ridgetop wind: moderate S-SWThursday: Precipitation 5-10mm, freezing level: 1100m, ridgetop wind: moderate S-SWThursday Night: Precipitation 10-15mm, freezing level: 700m, ridgetop wind: moderate-strong SWFriday: A mix of sun and cloud, light scattered flurries possible, freezing level: 900m, ridgetop wind: light SWSaturday: Precipitation 5-10mm, freezing level: 1100m, ridgetop wind: strong S-SW

On Monday, a slab avalanche size 2.5 was remotely triggered on a North facing alpine slope in the North Eastern part of the region. This slab released on the deep persistent weak layer buried in mid-February. Widespread activity occurred over the weekend caused by warm temperatures and strong solar radiation. Things have typically stabilized over the last few days due to cooler temperatures and lack of sun. Avalanche activity is expected to increase with warmer temperatures, new snowfall, and moderate-strong winds.

New snow may sit on a crust which exists up to around 1400m on solar aspects or on last week's storm snow (90cm+ in areas of the region). Winds slabs are expected to form in lee features from moderate-strong S-SW winds.Recent warmer temperatures have helped to settle the underlying snowpack. In shallower snowpack areas or on steep, unsupported features, the old storm slab may still be reactive to human-triggering. This older storm slab is sitting on a surface hoar, a crust, and/or facets buried at the beginning of April. Large cornices may still be a concern, especially during periods of warming or heavy loading. The early February crust/facet layer is typically down 1.5 to 2.5m. A smaller avalanche or a cornice fall may still have the potential to step down to layer causing very large, destructive avalanches.
