Around 9 a.m. Sunday snow showed up for the first time this season in the Omaha metro. Shortly after, power began to fail for thousands.
The number of customers without power rose to about 57,000.
"Trees just sagged onto power lines and that's what caused some of these outages," OPPD spokesperson Paula Lukowski said.
That caused problems around the city. Stop lights were failing, tree limbs fell blocking roads, and damaging power lines even further.
Traffic on the interstate slowed down for several crashes. OPPD crews rushed into action, working to restore power all afternoon and into the night.
"We expect to have a majority of customers back online tomorrow morning at some point with 99 percent back Monday night," Lukowski said.
More than 100 workers are on the job clearing downed limbs and making repairs.
"The numbers are coming down," Lukowski said. "We've brought in crews. We have about 100 employees including 18 tree crews that clean up debris for crews."
