In sintesi

Strong northerly winds naturally triggered a two foot deep slab avalanche on an east aspect of the North Ridge on Rendezvous Mountain at the Jackson Hole Mountain Resort on Sunday. Areas of unstable snow persist at the upper elevations and could be triggered by the weight of a person. Avalanches are unlikely at the mid and lower elevations.

    At the upper elevations slab avalanches one to two feet in depth could be human triggered in steep, wind loaded avalanche starting zones. These slabs lie upon a base of faceted snow that is most developed on steep, northerly aspects above an elevation of 9,000 feet These slabs were formed by north to southwest winds and are more likely to be triggered on northerly aspects but other slopes are also suspect due to the recent loading by strong north to northwest winds.

Avalanche Discussion

A northwest flow aloft will continue to bring areas of mid and upper level cloud cover to Western, Wyoming. Valley fog is likely to develop overnight. Wednesday will be dry with partly to mostly cloudy skies. Temperatures will rise into the 20s from overnight lows in the single digits. Winds will be westerly at 10 to 15 miles per hour.Some potential persist at the upper elevations for humans to trigger surface slabs one to two feet in depth in steep, wind loaded avalanche starting zones. The general avalanche hazard is expected to be MODERATE at the upper elevations and LOW at the mid and lower elevations.
