MCGREGOR (AP) - Thousands of Minnesotans are without electricity after powerful storms moved through central and northeastern Minnesota.

Strong winds of 50 to 70 mph knocked down trees and power lines overnight Monday.

Minnesota Power and Lake Country Power are working to restore service to nearly 17,000 customers at midday Tuesday.

Sheriff's dispatchers in Aitkin County say most of the wind damage is concentrated around McGregor and Big Sandy Lake.

At Eagle Point Campground in McGregor, a tree fell on a recreational vehicle, but there are no reports of injuries.
