South Rockies

New snow and variable moderate winds are likely to build new wind slabs throughout the day. Assess often for signs of instability as you transition into open alpine and treeline terrain.

No new avalanches reported.

Suspect new low-density storm snow to be redistributed by variable winds throughout the day building small wind slabs in lee terrain features

Roughly 5 to 10 cm of new snow will further bury variable surfaces of wind-affected snow, thin sun crusts, and soft snow. These upper layers have bonded well to a widespread supportive crust that is down 20 to 40 cm.

Below this crust, the shallow faceted snowpack is moist and starting to refreeze with cool temperatures. Two crust layers, one in the midpack and another near the base of the snowpack continue to be monitored. Avalanches on these layers are unlikely.

• Recent wind has varied in direction so watch for wind slabs on all aspects.
• Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
