Points saillants

Storm slabs may be reactive to human triggering, especially in wind loaded areas at upper elevations. Watch for signs of instability such as whumphing, cracking and recent avalanches.

Avalanche Summary

Storm slabs may be reactive to human triggers, especially in wind affected areas.

There have been no recent reports of avalanches in the region, however, there is very little information available at this time of year. If you get out into the mountains, let us know what you see by submitting to the Mountain Information Network!

Snowpack Summary

5-10 cm of new snow likely sits on a mix of melt-freeze crusts, hard wind slabs, sugary faceted snow, and feathery surface hoar crystals depending on location. Storm slabs may be reactive at alpine and treeline elevations, especially in wind affected areas. Total snowpack depth ranges from 50-100 cm and tapers rapidly at lower elevations.
