In the late evening hours of May 10 through the early morning hours of May 11, power was out for many people in the Oklahoma Panhandle. The cause was high winds damaging a transmission line in the Keyes area. Winds up to 70 miles per hour blew together two transmission lines and they burned through, falling to the ground.
The Guymon, Hooker and Optima areas were out for about an hour. Boise City, Felt, Keyes and Elkhart, Kansas were out of power for about four hours. At the height of the outage, as many as 12,700 were without power.
