CINCINNATI -- Smoke poured through the windows of a home in Walnut Hills Thursday, and left a woman in critical condition.
The fire started just before 9 p.m. in the 2200 block of May Street, according to Chief Marc Monahan.
Firefighters found an unconscious woman collapsed on the floor. Crews took her to the University of Cincinnati Medical Center where she remains in critical condition.
As crews worked to control the blaze, heavy smoke poured through the windows and spread in the side and front yard. There seemed to be no damage to neighboring houses.
Fire investigators found difficulty tackling the flames and smoke because of extremely cold temperatures.
"The elements are probably going to start taking effect," Raffel Prophett of the Cincinnati Fire Department said. "We actually have a warming bus."
Thirty firefighters battled the Walnut Hills blaze. By the time they arrived, the home was 70 to 80 percent engulfed. Even after the fire's bulk was put out, the home was destroyed.
