Information for the
December 2007 Ice Storm

Oklahoma Department of Emergency Management Web Page on the Event

A devastating ice storm cut off power to over one million people, and brought widespread damage and auto accidents to a large part of Oklahoma and surrounding states on December 8-11, 2007. Freezing rain accumulated on trees and power lines, bringing the lines down and leaving around 600,000 homes and businesses without electricity. Officials say it will several days to restore power to everyone. Hundreds of auto accidents were reported on ice slick roadways. The ice storm was the result of persistent widespread rain that fell into a shallow layer of below freezing air. This allowed the rain to freeze upon contact with exposed objects.
