Snow is available for transport, and with increasing westerly winds, human-triggered wind slabs are possible. Actively look for instabilities like shooting cracks and whumpfing.
Low-density snow coupled with moderate westerly winds will redistribute snow into lee terrain features at alpine and treeline elevations
Explosive-controlled storm slabs up to size 1.5 were reported in the Fernie area Saturday. Cornice noses are overhanging and may be reactive.
On Thursday several skier-triggered storm slab and dry loose up to size 1.5 were reported in the Nelson area.
New low-density snow is being redistributed by westerly winds, developing wind slabs over various surfaces of surface hoar, soft snow, wind-affected snow, and a thin crust formed on steep, solar-facing slopes. A crust now buried 30 to 40 cm deep seems to be well-bonded at lower elevations, in the alpine this may still need some time to bond.
Crusts and facets in the mid and lower snowpack can still be found in isolated pockets and we will continue to monitor them for signs of reactivity.
