| Extreme: Wide spread areas of unstable snow exist and avalanches are certain on some slopes. Backcountry travel should be avoided. |
| High: Mostly unstable snow exists on a variety of aspects and slope angles. Natural avalanches are likely. Travel in avalanche terrain is not recommended. |
| Considerable: Dangerous unstable slabs exist on steep terrain on certain aspects. Human triggered avalanches probable. Natural avalanches possible. |
| Moderate: Areas of unstable snow exist. Human triggered avalanches are possible. Larger triggers may be necessary as the snowpack becomes more stable. Use caution. |
| Low: Mostly stable snow exists. Avalanches are unlikely except in isolated pockets. |

At the mid and upper elevations, the possibility persists for backcountry travelers to trigger hard slab avalanches to the base of the snowpack in steep avalanche terrain. These slabs may fail after a slope has been crossed several times if a shallow weak zone is encountered. Larger loads, such as snowmobiles or groups of skiers, have a greater potential to cause failure of these weaknesses. Yesterday, a skier triggered an 18 inch soft slab on an east facing aspect in Avalanche Bowl on Teton Pass. Similar surface slides, along with loose snow sluffs, are also possible today. As the day warms, these slides will become more susceptible to failure. At the lower elevations, the avalanche hazard is limited to isolated pockets in very steep terrain.
