Highlights

Challenging travel conditions are the most hazardous part of the forecast for the holiday Monday. Use caution while traveling on steep open slopes where it may be difficult to arrest a fall and watch for low snow and exposed ground hazards at lower elevations.

Avalanche Discussion

Travel conditions likely continue to be your biggest hazard on Monday. Expect firm and icy slopes from refrozen surfaces after last week's rain event. Sunday's breezy weather kept many surfaces from softening, despite temperatures in the mid 30's. The wind should be less of a factor on Monday and allow the sun to soften the surface eventually. Breakable crusts may be found at lower elevations as well as open creeks and exposed ground hazards from low snow cover.

At lower elevations and later in the day, watch for weakening snow surfaces on slopes receiving direct sunshine or where temperatures rise above freezing. Roller balls are often the first indication that you could trigger a wet loose avalanche. Choose lower angle, or shaded slopes if you see evidence of weak snow surfaces. At higher elevations, you may find firm and icy slopes where a slip could turn into a consequential tumble. Be prepared to self-arrest or choose less exposed travel options.

-Previous discussion-

The snowpack at lower elevations really took a beating with the rain last week. See below for recent photos of the East South zone east of White Pass (1-16-21). Bumping Ridge at 4600 ft added 5 inches to its snowpack Monday and Monday evening before losing 8 inches to consolidation when the snow changed to heavy rain on late Monday night through Tuesday night. At higher elevations, Green Lake at 5900 ft added 8-14" of snow height before losing 7" to consolidation after the changeover to rain.

 

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.
