Permafrost / Permafrost thaw about to cause catastrophic lake drainage

Permafrost thaw is expected to cause catastrophic lake drainage and potential debris flow in 2015.
A rapid flow of water and debris is expected in a small creek valley west of Husky Lake, which lies in the Gwich' in Settlement Area (GSA).  The growth of a permafrost thaw slump will likely cause a small lake to drain catastrophically during 2015, resulting in a flash flood and possibly a debris flow. A flash flood could happen at any time during the summer or fall of 2015.
