Campbell said people should bring their own bedding as well as anything that makes them comfortable with them to shelters. “The morale remains pretty high in these areas. Oklahomans are always very resilient and they’re wonderful to keep their spirit up,” Campbell said. Ice accumulation on power lines has contributed to scattered power outages in the Oklahoma City area, city emergency manager Frank Barnes said. The Oklahoma City Fire Department is urging residents and businesses using generators to be careful and to keep them outside. “That’s the big concern now is if people are using generators in other parts of the state, they do produce carbon monoxide so you want to make sure they’re outside of the structure. Never use them inside or never use them even inside of a garage where those fumes could build up,” Oklahoma City Battalion Chief Brian Stanaland said.
