Thousands of people in southwestern Oklahoma are now in their sixth day without power.
Electric companies continue to work around the clock, but officials aren't sure how much longer it will take to restore electric service to everyone.
In some counties, hospitals and water treatment plants have been running on generators since Thursday. Emergency managers urge those who remain without power to visit one of the many shelters and warming areas that have been set up since last week's storm.
Chris Killmer, spokesman for Comanche County, said power companies managed to restore power to about 5,000 customers overnight. About 16,000 customers in Comanche County still were without power this morning, Killmer said.
City of Lawton officials are asking residents to conserve water after a generator running the Medicine Park treatment plant failed. Electricians are working to repair the generator and emergency operation workers have requested a backup generator from the state. In the meantime, the city will receive water from another treatment plant.
Killmer said officials hope to have power restored in most of the Lawton-area later today. In other areas of the county, Killmer said there's no telling how long power will be down.
On Sunday night, 2.5 miles of power lines fell in the Fletcher area, creating a setback to power companies.
"They're basically having to re-do everything," Killmer said.
Killmer said most residents are being self-sufficient and taking care of others.
"Now in day six of some people without power, we're asking them to check in on family and friends," Killmer said. "It may still be two or three days until they get power."
The county has nine emergency shelters, two warming centers and a feeding station set up to help people without power.
Junior Hardy, a volunteer at the emergency operations center in Altus, said much of Jackson County is still without power. Emergency operation workers are keeping people informed through radio broadcasts, Hardy said. Many people are using a shelter set up on Falcon Road, he said.
"It's still a mess," Hardy said. "Debris is everywhere. We're cleaning up and getting lines set up. We had some ice melt yesterday. Hopefully we'll get some more melting today."
A 63-year-old man found dead inside a trailer in Caddo County has been identified.
Virgil Poafpybitty died in his travel trailer where he stayed behind his family's house in southern Caddo County, said Police Chief Rick Decora of the Bureau of Indian Affairs in Anadarko.
Poafpybitty lived on land under BIA jurisdiction where power outages remain a problem today.
Saturday night Poafpybitty opted to stay in the trailer instead going inside the house, Decora said.
The trailer is more than 2 miles north of Stecker. The temperature inside the trailer was about 28 degrees when Poafpybitty was found Sunday.
Crews are making progress today restoring power to the area, Decora said.
Three Caddo County towns — Apache, Cyril and Cement — still were without power today at noon.
"It's really bad out there, but they're weathering through it," said Larry McDuffey, director of emergency management for the county.
Rural fire departments and other volunteers have been delivering meals and bottled water to residents, McDuffey said.
A secure juvenile facility in Manitou has been operating on emergency generators since Thursday. Officials said power might be restored to the Southwestern Oklahoma Juvenile Center on Wednesday.
The center also lost its source of water from Frederick today. The pumping station at the reservoir needs a new generator. Without a working generator, officials expect there will not be enough water pressure to have working rest rooms by Wednesday morning. Forty-eight adolescents are at the facility.
