It's all about that surface snow. If our persistently high freezing levels prevent a crust from forming, potential for wet loose avalanches in steep terrain will persist too.
Some potential for human triggered wet loose avalanches may still exist on steep slopes where a firm crust fails to form over the rain-soaked snowpack.
Sunday night: Cloudy with isolated showers. Moderate to strong southwest winds.
Monday: Cloudy. Light southwest winds. Treeline temperatures around +3 with freezing levels to 1750 metres.
Tuesday: Wet flurries transitioning to heavy rain in the afternoon; 20-30 mm accumulation. Moderate to strong southwest winds, increasing over the day and overnight. Treeline temperatures rising from around 0 to +4 over the day as freezing levels climb from 1400 to 2500 metres..
Wednesday: Rain; 20-30 mm accumulation. Strong south or southwest winds. Treeline high temperatures around +4.
No avalanches have been reported in the region and overall reports in the region remain limited. Be sure to post your observations to the Mountain Information Network!
Heavy rain has affected the snowpack at all elevations. With a bit of cooling over Sunday night we should see surface crust beginning to form and eliminate chances of wet loose avalanche activity. In areas where crust may fail to form (especially lower elevations), this potential could linger.
Average treeline snow depths are around 80-100 cm with much of treeline and all below treeline elevations still below threshold depths for avalanches.
Early season hazards such as rocks, stumps, and creeks are a concern below the alpine.
