Isolated pockets of wind slab have been reported in the alpine.
Early Season hazards such as rocks and trees are prevalent at lower elevations. Allow adequate time for egress and emergencies during these short days.
Pockets of wind slab exist in exposed alpine terrain. Significant wind transport has been reported near ridgetop and it is possible to trigger an avalanche in steep terrain, wind loaded terrain.
