Avalanche Summary

On Saturday, there was a report of a human triggered size 1.5 wind slab avalanche on a northeast aspect at 2600 m.On Thursday, there were reports of a few human triggered size 1 loose wet avalanches at treeline within the new snow.

Snowpack Summary

15-25 cm of recent storm snow in the alpine and at treeline sits on a melt-freeze crust on all aspects except for north slopes above 1800 m, where it sits on dry snow. Snow is disappearing rapidly at lower elevations.

Problems

Wind Slabs

Up to 25 cm of recent storm snow sits on a crust in most locations, and on dry snow on north facing alpine terrain. Strong southwest winds will have formed wind slabs at upper elevations.

Be careful with wind loaded pockets, especially near ridge crests and roll-overs.

Aspects: North, North East, East, North West.
