The alpine rating is Loose Dry., the treeline rating is , and the below treeline rating is Known problems include
Convective flurries produced 10-15cm in the West side of the park on Friday evening.
Be mindful of how the new snow is bonding to the crust and if more snow falls than forecasted, the hazard could increase.
A few small dry loose avalanches were observed in the park on Saturday running from steep terrain features.
Earlier in the week, numerous afternoon solar triggered avalanches sz 2-2.5, with isolated sz 3's. Some of these avalanches, occurring at treeline and below, have failed at the ground and gouged deep into the snowpack.
Deep persistent slabs are a concern, with a report of a cornice-triggered pocket high on Mt Smart failing to glacial ice, as well as a deep slab on Mt Fidelity.
10-15cm of new snow covers widespread crusts on solar aspects and patchy surface hoar in sheltered terrain. Warm temperatures have rapidly settled the snowpack this week.
Below this is a generally strong snowpack, however the basal weakness of rounding facets/decomposing crust near the ground should factor into how you use the terrain.
A broad upper trough will continue to create unsettled weather through Sunday bringing isolated flurries. On Monday a ridge of high pressure from the north invades the province bringing dry air and a clearing trend.
