Avalanche Summary

No recent notable avalanches have been reported.

Snowpack Summary

Up to 45cm of new snow at upper elevations accumulating Thursday and Friday has begun to settle and bond and has been redistributed by southerly winds. This new snow sits on a sun crust or moist snow on steep south-facing slopes, cold dry snow on northerly aspects, and an overall well settled snowpack. Thursday's precipitation fell as rain below 1200m where the surface snow is either wet or presents as a crust.Cornices have formed on many alpine ridge lines. They will become touchier as they grow in size, as temperatures rise, and as they are subject to the strong late-winter sun on clear days.
