Overview

A few weak thunderstorms developed near Lake Mille Lacs the evening of the 26th ahead of a cold front. While the overall threat of severe storms was low, one of the storms did produce a waterspout over Farm Island Lake that did produce damage along the shore. This storm produced additional funnel clouds, but no other waterspouts or tornadoes were reported.

Summary: The waterspout developed over the northwestern arm of Farm Island Lake east of Johnson's Point and moved to the southeast, passing just offshore of the southwest tip of the point. It then turned a little more easterly and passed near or over the northern tip of First Island and over open water before moving over the southern part of Delicarlia Peninsula. Docks were damaged at this location along with a few boats flipped and tree damage. The waterspout then turned more easterly and moved across Church Camp Bay before reaching shore again, damaging another dock, flipping multiple boats and causing sporadic tree damage. It then turned a but more southeasterly and traveled through a grove of trees and dissipated before reaching US Highway 169. We would like to thank Scott Boyd of Farm Island Repair & Marine and Cheryl McDonough of the Farm Island Lake Improvement Association for their assistance in gathering information on this event.
