Avalanche Summary
Cornices were triggered by explosives in the north of the region on Saturday, which produced up to size 2 avalanches.Expect natural and human-triggered avalanche activity to increase with the recent snowfall and strong winds.
Snowpack Summary
Around 10 to 20 cm of storm snow fell Friday night and another 15 to 30 cm is forecasted Saturday night into Sunday. These storms have had strong westerly winds associated with them. Expect touchy storm slabs on all aspects with thicker slabs in lee features. All of this snow fell on previously wind-affected surfaces. The new snow may not bond well to these surfaces and could be reactive to both natural and human triggers.In the southern parts of the region, a widespread crust exists around 40 to 80 cm deep. Well-consolidated snow exists below the crust.Also make note of cornices at ridgeline. Variable winds in the past month have produced cornices on all aspects. They will become touchier as they grow in size, as temperatures rise, and as the sun packs a strong punch on clear days. Stand well back of them and avoid them from below!
