Another pulse of heavy snow with strong winds will continue to build large storm slabs. Where the wind forms thick wind slabs, avalanches could be large enough to damage trees or cars. Avoid traveling on steep wind-loaded slopes. Cracking, recent avalanches, and test slopes that slide easily are all signs of instability. But even if you don't see obvious signs, err on the side of caution and stick to low-angle slopes, sheltered from the wind. You could trigger an avalanche on most steep slopes, but steep wind-loaded slopes are likely to be the most dangerous places. You can identify wind-loaded terrain using visual clues such as drifts and textured surfaces. With wind speeds up to 60mph, wind slabs are likely to form in odd locations, farther downslope, or in typically sheltered terrain.
Areas near the Cascade Crest continue to be favored with higher snow totals, so expect more widespread and larger avalanches farther west in the zone.
