The National Weather Service says a weak tornado caused minor damage at Lake Cochrane in South Dakota’s Deuel County over the weekend.
The afternoon twister had estimated peak winds of 75 mph and was rated an EF-0, the weakest on the enhanced Fujita scale.
Weather service officials say the tornado touched down on the lake’s northern shore and traveled less than a mile before lifting. It caused mainly minor damage to docks, boats, boat lifts, canopies, trees and shrubs, though two houses suffered damage. One lost a portion of its roof.
