In sintesi

You may be able to trigger small loose avalanches on slopes near to 40 degrees. There's a chance you could find shallow, fresh wind drifts at upper elevations. For Sunday, expect light snow and increasing wind.

    You may be able to trigger small and shallow avalanches in light, dry surface snow over a slick crust. These avalanches may pose little risk on most slopes. Use caution in very steep, extreme terrain and around terrain traps like cliffs. In this terrain, even a small avalanche could result in injury. In places, it may be difficult to trigger loose avalanches. Light snowfall Saturday night and Sunday will add to a couple of inches of weak snow already on the crust. Observers have reported surface hoar and facets on top of the crust which could make the new snow slide easily.  Use small test slopes to see if the snow slides on the crust. 

Avalanche Discussion

Expect between 1-4" of light, dry snow by the end of Sunday. Winds may be just strong enough for some light snow transport above treeline. If you find more significant fresh drifting, use caution on steep slopes. The last couple of days have brought dustings of snow totaling 3 inches or less. Otherwise, snow surfaces are firm and icy.  Travel could be dangerous on steep slopes, especially where you could slide a long way or hit rocks, trees, or cliffs. Make sure you can stop a fall and think about the consequences before traveling on steep slopes. Open creeks and downed trees pose another hazard while traveling through the mountains. 

On Friday, observers reported small loose avalanches on steep, sunny slopes near treeline. An impressive storm resulted in an avalanche cycle on January 12th around Stevens Pass and much of the Cascades. In places, you can see still see the evidence of avalanches that ran later in the storm. Earlier this week, I checked out one of these avalanches in the historic Wellington path on Windy Mountain. While the path could produce much larger avalanches, this slide was easily big enough to break mature trees or bury a car. The debris piles were over 12 feet and deeply gouged in places. Debris from these older avalanches is a reminder that avalanches can be dangerous.

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.
