Points saillants

You may still trigger a wind slab in isolated areas like rocky steep terrain features where winds have recently transported snow.  At lower and mid-elevations move to shaded or lower angle terrain where you find wet and weak snow.  

Avalanche Discussion

It should be another cool day above treeline with strong E-NE ridgeline winds.  Mid and lower elevation temperatures should warm slightly on Tuesday under mostly sunny skies.  

10" of new snow fell near White Pass Friday night and Saturday.  New snowfall amounts tapered off further east of the Cascade crest. An observation near the West South/East South boundary reported that extreme winds and new snowfall led to large natural slab avalanches.  Wind slabs likely formed further below ridgelines than usual.  Use care when approaching steep rocky terrain with wind loaded snow, this may be the last best spot to trigger a wind slab avalanche.  Use clues such as textured and hollow snow layers to identify which slopes to steer around.

Cornices are large and will fall down during the spring.  Give them space along ridgelines and don't hang out on slopes below large overhanging cornices. Be prepared for travel hazards like exposed creeks, trees and rocks as southerly slopes and lower elevations continue to melt out. 

Stay tuned to the avalanche danger as temperatures warm later this week.  If you're out,  share what you see and submit an observation

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.
