Storm slab size and sensitivity is trending towards HIGH through Monday with heavy snowfall and strong winds.
As storm snow continues to accumulate, reactive slabs may form at all elevations. Deeper and more reactive slabs are likely in wind-loaded, northerly terrain at higher elevations.
No recent avalanche activity has been reported in the past several days. However, storm slabs have been reactive to riders and explosives in the neighbouring Sea to Sky region, and both regions have experienced similar stormy weather.
Natural avalanche activity remains possible with continued storm snow accumulation.
Stormy conditions continue to build the previously thin snowpack. A thin melt-freeze crust caps most surfaces or is just under the most recent flurries, covering 30-60 cm of snow that accumulated over the week.
Beneath the recent snowfall, the snowpack is generally well-settled, consisting of moist, dense snow. Snow depths at the treeline are estimated to range from 50 to 130 cm.
