Snowpack Summary

A solid melt-freeze crust has developed at all elevations on most aspects. New snow may bury surface hoar that has grown at and below treeline over the past few days. In the alpine new snow may not bond to the old surface depending on the timing of the cooling. Deeply buried weak layers continue to exist, however the bridging effect of the re-frozen upper snowpack may reduce the likelihood of triggering.

Problems

Wind Slabs

Some thin new wind slabs may develop due to the new snow and wind.
