In sintesi

Watch for wind slab development locally on Monday. Increasing winds may start to move the 20–40cm of recent snow.

Great skiing up high, but expect early-season hazards down low.

    There has been little wind over the past week since 20-40cm of snow fell. Monday will see increased winds in the alpine, but we are uncertain how much this will translate into wind slab development. Monitor this locally.

Moderate

Avalanche Summary

No avalanches reported in the backcountry today. Sunshine Ski Hill was getting small wind slabs (size 1) with explosives in Delerium Dive.

Snowpack Summary

20-40 cm of storm snow from last weekend is settling and bonding. Isolated thin wind slabs exist on high-alpine lee aspects. Below ~2300 m, a rain crust exists below the storm snow. The mid- and lower-snowpack is well settled where thicker, and facetting (getting weaker) where thin. Tree-line snow depths range from 70-125cm.

Weather Summary

Monday will see increased NW alpine winds (up to 50 km/h), a trace of new snow, and, at treeline, daytime highs of -9C.

Not much changes on Tuesday except for lighter winds.
