Highlights

Yesterday a snowmoblier was partially buried but not injured west of Togwotee Pass after triggering a slab avalanche on a southeast aspect. On Saturday another rider outran a 30 inch deep slab avalanche on an east aspect in the Salt River Range. In our area buried layers of faceted snow continue to be a problem at the mid and upper elevations. Warming temperatures will increase the potential for humans to trigger persistent slab avalanches. Avalanches are unlikely at the lower elevations.

    At the mid and upper elevations buried layers of faceted snow exist within the snowpack in some areas, near the base of the snowpack in other areas, and in some locations a shallow early season snow pack is entirely faceted. Humans could trigger slab avalanches on these weak layers. Slab depths are likely to be 30 inches or less on most aspects, however steep northerly aspects above an elevation of 9,000 feet have some potential to produce dangerous full depth avalanches.

Avalanche Discussion

One more day of the same weather is forecast before the flow aloft backs to the southwest ahead of an approaching trough. On Wednesday skies will be mostly sunny with temperatures rising into the 30s. Winds will be backing from the west to the southwest at speeds of 25 to 30 with higher gusts. The general avalanche hazard is expected to be MODERATE in terrain with greater than three feet of settled snow. Slab avalanches up to 30 inches in depth could be human triggered on some very steep slopes. Some potential remains for human triggered full depth slab avalanches in steep northerly terrain above an elevation of 9,000 feet.
