Lo esencial

Backcountry travelers have the potential to trigger persistent slabs on a variety of aspects and elevations today. Isolated pockets of newly formed wind slab could also be triggered in steep, wind-loaded terrain to depths of six inches. Periods of sunlight and warming termperatures will further weaken these hazards during the afternoon hours. Careful snowpack and terrain evaluation is necessary for safe travel in avalanche terrain today.

    Persistent weak layers exist in the snowpack. These layers formed during cold, dry periods and were buried on December 8th and January 5th. The weight of a single person could still cause failure of these weak layers creating a slab avalanche with depths of one to four feet. Larger loads, such as groups of people or snowmachines, are more likely to trigger one of these events.

Avalanche Discussion

( Discussion is generated from the previous day's afternoon forecast. )Northerly flow will back to the northwest as a ridge of high pressure moves easterly over the region. Skies will be partly cloudy to mostly sunny. Inverted temperatures will develop overnight with mountain highs reaching into the upper 20s during the day. Nighttime lows in the valleys will be near zero before rebounding into the mid to upper 20s. Northwesterly ridgetop winds will range from 5 to 15 miles per hour.The general avalanche hazard is expected to be Moderate on Wednesday and will increase during the day on sunlit aspects as warm temperatures and sunshine heat the snow surface. In steep, wind-loaded terrain, backcountry travelers could trigger recently formed wind slabs ranging from six to eighteen inches in depth. The chance of triggering persistent slabs up to four feet deep continues. Faceted snow near the base of the snowpack remains a concern in the Togwotee Pass area. In the Tetons and the Greys River area, a slight chance continues for avalanche activity on these basal facets.
