Avalanche Forecast
Regions: Olympics.
A winter storm will bring fresh snowfall to the Olympics through Thursday. However, with thin snow coverage in much of the zone, the avalanche hazard will be limited to lee slopes at higher elevations. Approach areas with freshly drifted snow cautiously, steering around steep unsupported slopes. Watch for low snow coverage and ground hazards everywhere else.
Discussion
With a lack of snow so far this season, weather stations in the Olympics are only averaging between 5-10 inches of snow depth prior to this storm. The new snow predicted through Thursday will help, but not radically change the early season landscape in terms of snow cover or depth. Besides the new snow, winds will be strong enough to transport and load lee slopes at upper elevations.Â
It's on steep lee slopes at higher elevations where you'll likely encounter enough snow for an avalanche hazard and where fresh or recently formed wind slabs may be found. Steer around steep unsupported slopes with wind-drifted snow cautiously, feeling for firm or hollow sounding snow as a sign that wind slabs may be present. You can stay safe by traveling on ridges, wind-scoured areas and any slope less than 35 degrees.
Be especially cognizant of the consequences of even a small avalanche with so many shallowly buried ground hazards, like rocks, stumps, and creeks.
Forecast schedule
For the 2019-20 winter season, avalanche danger ratings will be issued for the Olympics every Friday through Sunday and during mid-week holidays.
During the week, No Rating will be issued but forecasts will include expected conditions and relevant travel advice. While this avalanche forecast is focused on backcountry avalanche conditions expected predominately in the Hurricane Ridge area, we want to hear your observations from anywhere in the Olympics.Â
