Avalanche Summary

No new avalanches have been reported. Storm slab avalanches will become reactive throughout the day on Sunday, particularly on wind loaded slopes.

Snowpack Summary

A midday storm will deliver 20-30 cm of new snow by Sunday afternoon. Expect thicker and touchier storm slabs to develop on north and east facing wind loaded features. The new snow may bond poorly to sun crusts on steep south facing slopes. The mid and lower snowpack are well settled and stable.
