Olympics
Avalanche danger
Highlights
You may trigger a small avalanche on steep slopes where wind deposited snow 6” or deeper above a stout crust. Be suspicious around smooth pillow-like features or in areas below sharp cornices. Make sure you can arrest a fall when traveling on firm, icy aspects.
Avalanche Discussion
Light to moderate sustained SSW ridgetop winds Tuesday through Wednesday morning likely transported shallow snow onto lee slopes. Pay attention to the snow near the surface. If you see smooth pillow-like drifts or find evidence of recent sharp cornice features, wind slabs lurk. On slopes greater than 35 degrees you can trigger an avalanche where you find pockets of wind-drifted snow deeper than 6” above the 1/13 rain crust. In nearby zones, weak snow or thin sun crusts overly the stout 1/13 crust and may contribute to wider slab propagation than you expect. Even though we think these potential avalanches should remain shallow, they can still harm you on steep slopes above cliffs, gullies, rocks, or trees.
Successive waves of snow Tuesday night and another anticipated Wednesday night continue to favor deeper snow accumulations along the eastern side of the Olympics with minor accumulations at Hurricane Ridge. Recent observations in the eastern Olympics have been limited. As a result, we have a high degree of uncertainty in this area. If you head out into the mountains please let us know what you find.
Despite the recent snow, variable travel conditions still exist. You may encounter soft dry snow, breakable crusts, firm icy slopes, and patches of bare ground.
2020-21 Forecast Schedule: Avalanche danger ratings will be issued for the Olympics every Friday through Sunday and during mid-week holidays. During the week when the Hurricane Ridge road is closed, forecast information will be updated daily to include expected conditions and relevant travel advice under the No Rating label.
During the ongoing Covid-19 pandemic, continue to follow the latest guidance from local, state, and federal health officials. Avoid unnecessary risks that could impact first responders and stress medical resources. Wear a mask when appropriate, practice social distancing, and consider recreating closer to home.
