Points saillants

Strong winds may create the potential for avalanches in terrain where the snow drifts into thicker deposits. You may trigger a slide on steep slopes when you find smooth pillow-like piles of snow or in areas below sharp cornices.

Avalanche Discussion

Windy conditions will headline this next small storm for the Olympic mountains. Strong southerly winds expected overnight should easily transport any available snow and may result in freshly formed slabs on lee slopes and scoured surfaces on exposed ridges. Pay attention to what the snow surface looks like. If you see smooth pillow-like drifts or find sharp cornice features, you found potential wind slabs. You may trigger pockets of wind drifted snow on slopes greater than 35 degrees. With such strong southerly winds, you could find slabs in some unusual locations like well below ridgeline, and along the sides of mid-slope features. 

While we don’t expect much snow at Hurricane Ridge, this flow pattern may produce deeper accumulations along the eastern side of the Olympic. Recent observations in this area 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.
