East Slopes South

You could still trigger a windslab near and above treeline where recent drifts rest on a crust. There's an increasingly low probability of triggering a persistent slab avalanche, but if you do, the consequences of triggering one are high. Consider checking for weak snow above the crust in your terrain before committing to larger, steeper slopes. 

The weather on Tuesday should be conducive to avalanche problems continuing to heal before the danger rapidly increases Tuesday night into Wednesday.

Higher elevation slopes closer to the Cascades Crest picked up 5-6" of snow Friday afternoon and night, which was accompanied by strong winds lingering into Saturday. Shifting wind directions formed slabs on a variety of aspects. These slabs may sit atop a thin crust or directly above the 12/21 crust. The crust provides efficient bedsurfaces for avalanches to run on. If you are traveling near and above treeline, feel for firmer or hollow sounding snow and use caution around steep open slopes that have been recently wind loaded. Where you find wind-stiffened snow, assume you can trigger a wind slab avalanche on similar terrain features.

We don't have much information regarding a persistent problem that continues to be present in the adjacent Cascades East Central zone. We suspect the East South zone is similar in that if this problem exists, it is becoming unlikely to trigger such an avalanche, however, the consequences warrant serious consideration. Check adjacent test slopes for weaker snow above the 12/21 crust before committing to larger terrain features. To maintain a margin of safety, keep your distance from slopes 35 degrees and steeper that are open enough and tall enough to produce large avalanches. Watch for obvious signs of instability like recent avalanches, whumphing collapses, or cracks shooting through the snow. Look for weak snow just above a thick melt-freeze crust roughly 1.5ft to 3ft below the surface, above 5,000ft. S

Snow cover at upper elevations is increasing but remains shallow below treeline and at all elevations further east and away from the Cascade Crest. Typical early season hazards are still in play and you'll likely encounter open creeks and exposed stumps and rocks.
