Avalanche Summary

Our field team observed small loose wet avalanches out of steep south aspects near Mt Cain on Wednesday. Storm slabs and wind slabs will be the main concern as new snow accumulates.

Snowpack Summary

10 to 20 cm of new snow will fall on Friday, with deeper deposits in lee terrain. In most areas this snow is falling on moist or crusty snow layers, except shaded terrain above roughly 1600 m where the snow has remained dry over the past week. The middle and lower snowpack are strong and bonded.
