Avalanche hazards are limited to small slab avalanches and loose snow sloughs in very steep avalanche prone terrain. Humans who venture into steep avalanche starting zones and cliff areas could trigger slab avalanches 6 to 18 inches deep and loose snow sloughs. Even small slides can become dangerous in terrain with consequences, like steep confined couloirs, cliff areas and slopes above terrain traps. Today's sunshine may cause some wet loose snow sloughs to release naturally on steep sunlit aspects.

An approaching trough from the northwest will move into the area overnight. This low-pressure system is expected to deliver light snowfall through Friday with 3 to 6 inches of accumulation in the mountains. By morning, there should be a few inches of new snow. Mountain temperatures will start in the teens and then warm into the mid-20s. Southwesterly winds will be in the teens and are expected to lessen throughout the day. The snowpack is mostly stable, and the avalanche hazard is expected to be Low in all the forecast areas. Since early March, the snowpack has undergone many melt-freeze cycles, causing the buried weak layers to become unreactive. The avalanche hazard is limited to surface snow, and at the higher elevations, skiers and riders could encounter small winds slabs up to 18 inches in-depth and loose snow sluffing. These hazards could become dangerous in serious terrain, like steep couloirs, slopes above cliffs, or slopes above terrain traps.
