Avalanche Forecast

Moderate - Forecast snowfall amounts are uncertain on Wednesday

WEDNESDAY: Flurries, accumulation 10-15cm / Moderate south wind / Alpine temperature 0 / Freezing level 1400mTHURSDAY: Flurries, accumulation 5-10cm / Moderate to strong south wind / Alpine temperature -1 / Freezing level 1300mFRIDAY: Snow, accumulation 15-30cm / Moderate south wind / Alpine temperature -1 / Freezing level 1200m

There is no recent avalanche activity to report. On Wednesday, wind slabs may remain reactive in human triggers at upper elevations. In northern parts of the region, the deeper February weak layers continue to present a low probability / high consequence scenario.

Expect another 10-15cm of snow at upper elevations to add to the storm snow amounts from last weekend which totalled roughly 40 cm around Coquihalla and Allison Pass and 30 cm around Duffey Lakes. Freezing levels reached roughly 1400 m at that time, resulting in rain and/or wet snow at lower elevations. Thicker wind slabs and large cornices likely exist in alpine terrain. The storm snow sits above a widespread rain crust up to about 2100 m, but the snow has likely formed a good bond to this crust. In the north of the region, the February weak layers are 80-120 cm deep and include a buried surface hoar layer that recently produced a few persistent slab avalanches and a crust/facet layer that appears to be gaining strength. In the southern parts of the region, the lower snowpack is generally stable.
