Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Recently, dribs and drabs of snow have fallen on a variety of surface forms. The bond of this new snow will need to be monitored as incremental loading may occur over the next week or so. Previous warm temperatures created moist surface snow on sunny aspects and on all aspects at low elevations. Where a re-freeze has occurred, a crust now exists. Surface hoar (5mm) has been forming on that crust at treeline and below. Last week's storm snow appears to be settling and bonding well. A facet layer which formed in mid-January has gained strength. It showed hard, resistant planar results in a compression test at treeline in the Hankin area on Sunday.

Avalanche Problems
