Multiple waterspouts and funnel clouds were observed and photographed from Shelter Island and by pilots. These originated in the Berner's Bay area and moved to Point Couverden through marine zone 13.

The wider storm

A blocking pattern occurred for Southeast Alaska in early December. A strong arctic high cell built over central Alaska on Sunday, 12/2 and moved slowly southeastward through Thursday, 12/6. The arctic front remained south of the Lynn Canal through the period and strong outflow winds occurred there due to extreme surface pressure gradients north of the front.

Began near Point Retreat (58.7198, -134.9835).
