Use caution in wind-loaded areas where more cohesive slabs remain possible to human trigger.
Investigating the bond between new snow and underlying surfaces before committing to terrain.
15-20 cm of storm snow and moderate winds have built deep cohesive pockets of storm snow in lees. This new snow buried a weak layer of surface hoar and a crust.
Through the weekend, the storm snow was reactive to skier triggering with several, size 1 to 1.5, storm snow avalanches being reported. Storm snow was particularly reactive in exposed areas where wind affect had built deeper pockets of storm snow.
Thank you to everyone who has been sharing observations on the Mountain Information Network. All the information and photos are very appreciated by forecasters!
15-20 cm of recent snow overlies a layer of surface hoar in sheltered areas and a melt-freeze crust elsewhere. Pockets of deeper wind-deposited snow can be found at treeline and above and have been reactive to human triggering.
Overall, the snow depth remains relatively shallow, with numerous hazards present at or just below the snow surface across all elevations.
