On Tuesday there were reports of several wind and storm slabs running naturally size 1, 1.5 and 2 on south, east and north aspects in the alpine. There were also a few skier/rider triggered size 1 and 1.5 thin storm slab avalanches.

Reports from Saturday, Sunday and Monday show numerous loose dry avalanche size 1-1.5 running in steep terrain in the alpine and at tree line. There were also a few skier and rider along with naturally triggered storm and wind slab avalanches size 1-1.5 on a variety of aspects in the alpine and at treeline.

30-70 cm of snow accumulating through the last week overlies older wind-affected snow at high elevations, or a melt-freeze or rain crust to a variable upper extent of 1700-2400 metres in elevation. Moderate to strong winds have redistributed this new snow onto a variety of aspects.

The mid and lower snowpack are generally well settled and strong. Although isolated, there are two deeper weak layers that may persist in some areas. A weak layer of surface hoar buried 90 to 170 cm deep may be found across the north of the region while a facet/crust layer from November may be found near the ground in shallower snowpack areas.

• Wind slabs are most reactive during their formation.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Seek out sheltered terrain where new snow hasn't been wind-affected.
• Use extra caution around cornices: they are large, fragile, and can trigger slabs on slopes below.
