Avalanche
A natural avalanche cycle ran in two waves- most overnight on 12/28 with a later wave early 12/29. The largest and most widely propagating slides ran on ATL NE early in the storm, likely early on 12/28. Some large slides on E aspects ATL had fairly impressive propagation, too. W aspects ATL had mixed results, with some avalanches running large, others remaining small.
