Repair crews were working to restore electricity in several states Monday after a weekend ice storm knocked out power to more than 410,000 customers in the Central Plains and Midwest, power companies said Monday.

The storm entered Oklahoma early Sunday, bringing freezing rain that caused significant ice accumulation on trees and overhead power lines. The weight of the ice pulled down tree branches and power lines, cutting power.

That system later moved into Kansas, Missouri and Illinois.
