Snowpack Summary

Not much change in the snowpack in terms of new snow. What was noted today was the increase in alpine winds. By the end of the day there was ongoing transport in most alpine areas. Windslabs remain the most significant problem in gullies. They may be growing in thickness, and becoming more reactive as they become stiffer.

Problems

Wind Slabs

Windslab distribution is changing as the winds move snow. Expect slabs in gullies and cross loaded areas to have become thicker and likely stiffer.

Choose well supported terrain without convexities.Caution in lee and cross-loaded terrain near ridge crests.
