Recent snow and strong southwest winds may form fresh wind slabs reactive to human triggers.
Avoid steep, rocky, and wind-affected areas where triggering slabs are more likely.
Recent snow and strong southwest winds may form fresh wind slabs reactive to human triggers on lee features at treeline and above.
A persistent weak layer of surface hoar or facets is buried 40 to 80 cm. Rocky slopes with a convex shape on northerly and easterly facing aspects at treeline and above are the most likely places to trigger this layer.
No new avalanches were reported in this region on Wednesday.
Up to 40 cm of recent snow and southwest winds formed slabs that may still be reactive to human triggers.
In most areas, the storm snow rests on a melt-freeze crust, except for high-elevation north and east-facing slopes.
A persistent weak layer of surface hoar or facets from late January is down 50 to 100 cm. Rocky slopes with a convex shape on northerly and easterly facing aspects at treeline and above are the most likely places to trigger this layer.
