Several large, natural storm slab avalanches up to size 3 were reported on west and northwest aspects in the alpine on Thursday. 

20-30 cm of recent snow at upper elevations and strong southerly winds have created fresh storm slabs reactive to human triggers.

At treeline and below, the snow was likely moist and has formed a surface crust.

A crust formed in early November has been reported down 80-120 cm. There has been some evidence of large avalanches running on this crust. This will be a layer to monitor throughout the season.

• Give the new snow time to settle and stabilize before pushing into bigger terrain.
• Watch for signs of instability like whumpfing, hollow sounds, shooting cracks or recent avalanches.
• Be especially cautious as you transition into wind affected terrain.
• Avoid freshly wind loaded terrain features.
• Remember that the snowpack will be significantly different at higher elevations than lower down.
