Avalanche hazard remains limited to lee slopes at higher elevations. Approach areas with freshly drifted snow cautiously and avoid steep unsupported slopes. Watch for low snow coverage and ground hazards everywhere else.

Discussion

The new snow received through Thursday did not radically change snow cover or depth throughout most of the zone. 

Steep lee slopes at higher elevations are the only locations where you'll likely encounter enough snow for an avalanche hazard. There you might find recently formed wind slabs. Steer around steep unsupported slopes with wind-drifted snow. Look for firm or hollow sounding snow as a sign that wind slabs may be present. You can stay safe by traveling on ridges, wind-scoured areas and slopes less than 35 degrees.

Be especially cognizant of the consequences of even a small avalanche with so many shallowly buried ground hazards, like rocks, stumps, and creeks.

Forecast Schedule and No Rating definition

At this time, we do not have enough specific snowpack information to issue an avalanche hazard rating for the East South zone. However, even when No Rating is applied, applicable avalanche conditions and backcountry travel advice will be provided throughout the season. When weather systems produce very dangerous avalanche conditions in adjacent zones, NWAC will issue an avalanche warning for this zone as well.
