Snowpack Summary

The next storm on Thursday and Friday will add to the recent 15 cm of snow. Upwards of 30 cm of snow is possible with the storm, and it will fall with strong southwest wind. All of this snow overlies a heavily wind affected layer in exposed terrain and pockets of feathery surface hoar crystals and faceted snow in sheltered terrain.In the south of the region, the remainder of the snowpack is well-settled.Around Bear Pass and in the north of the region, you may find two weak layers of surface hoar buried between 50 and 100 cm. The base of the snowpack may also be composed of weak and sugary faceted snow.
