Lizard-Flathead

Up to 70 cm of new snow and west winds have formed fresh storm slabs that will be most reactive in wind affected terrain.

Make conservative terrain choices and avoid overhead hazard.

Moderate

• Uncertainty is due to the limited number of field observations.

On Wednesday, numerous explosive triggered storm slab avalanches up to size 2 were reported primarily at treeline and above on a variety of aspects.

Strong southwest winds on Thursday could trigger natural avalanches on lee aspects.

50-70 cm of new snow and strong west winds have formed slabs overlying a thick crust.

Below the crust, the snowpack is moist to the ground.

• Make conservative terrain choices and avoid overhead hazard.
• Avoid freshly wind-loaded features, especially near ridge crests, rollovers, and in steep terrain.
• Use small, low consequence slopes to test the bond of the new snow.
• Closely monitor how the new snow is bonding to the crust.
