Partly cloudy skies are expected today with some area of lingering light snowfall.

The Bridger-Teton Avalanche Center will be conducting an investigation of this accident. Also over the past week, there have been many large human-triggered and natural avalanches in the forecast areas as well as a full burial on February 14 south of Spread Creek in the Togwotee Pass area. Above 8,000 feet, backcountry travelers could encounter dangerous avalanche conditions today, and when traveling in avalanche-prone terrain are likely to trigger large to very large avalanches. Heightened avalanche hazards exist below an elevation of 8,000 feet where the avalanche hazard is rated as Moderate and human-triggered avalanches are possible on some steep avalanche terrain. Expert snowpack and terrain analysis skills are essential for safe travel in avalanche terrain, and if triggered slides could run long distances. Today's Avalanche Problems Persistent Slab ASPECT/ELEVATION: All elevations and aspects except S-SW below 7500' Likely Large to Very Large Steady trend DESCRIPTION At the higher elevation, humans could trigger large to very large slab avalanches on persistent weak layers of faceted snow. These dangerous avalanches could be up to four feet deep and could run long distances. At the lower elevations, below an elevation of 8,000 feet, small to large slab avalanches up to 2 feet in depth could be human triggered on steep avalanche prone slopes. Wind Slab ASPECT/ELEVATION: All aspects above 9000'; N-E-S above 7500' Possible Small to large Steady trend DESCRIPTION In steep, wind-loaded terrain above 8,000 feet, skiers and riders could trigger small to large wind slabs 1 to 2 feet deep. These wind slabs could step down to weak layers deeper in the snowpack and become a large persistent slab avalanche.
