Aided by easing winds and spreading snow, firefighters advanced on a wildfire fueled by fierce gusts that sent nearly 10,000 people from their homes as it sparked blazes throughout an affluent community at Reno's edge.
Authorities said that the worst was likely over as growing flurries and falling temperatures stoked hopes that the remaining showers of ember and ash would die down.
The fire was blamed for the death of a 74-year-old man who had a heart attack while trying to flee. It also left a firefighter with first- and second-degree burns and sent 16 people to hospitals, many for smoke inhalation.
Fire officials cited winds of up to 60 mph as a driving force of the northwestern Nevada fire early Friday that also destroyed or damaged up to 25 homes.
Reno Fire Chief Mike Hernandez said that firefighters made large advances against the blaze.
"The winds are laying down which is greatly improving our ability to manage the fire," he said just before sunset, adding that snowfall will also help extinguish hot spots.
But fire officials at an evening news conference weren't ready to declare victory.
"The threat to homes is still there," said fire spokesman Mike Regan. "There is still a lot of hot embers and dry fuel out there. We don't have a good established line around the fire."
More than 100 police officers and National Guard members were patrolling streets in the fire area to protect homes from vandals, Assistant Police Chief Mke Whan said.
The wind carried embers up to a mile, attacking upscale homes in random spurts. Police went house-to-house, pounding on doors and urging residents to evacuate in the dark of the night. Flames at times reached 50-feet high.
The cause of the blaze wasn't known, but a downed power line or homeless encampments in the area might be to blame, Hernandez said. He said the region is also a popular area for teenagers who might have started the fire to stay warm.
At least 400 firefighters from as far as 260 miles away flocked to Reno early Friday as multiple fires roared from the Sierra Nevada foothills in northwestern Nevada and spread to the valley floor.
The wind grounded firefighting helicopters and made it difficult for firefighters to approach Caughlin Ranch, the affluent subdivision bordering pine-forested hills where the fire likely began after 12:30 a.m. It also helped the fire spread from 400 acres to more than 3 square miles.
"The wind is horrific," said Reno spokeswoman Michele Anderson. "We just watched a semi nearly blow over on the freeway."
Hernandez said residents ran from their homes dressed in pajamas, frantically trying to grab as many possessions as possible. One elderly man dressed in his underwear ran out with a blanket wrapped around his body.
Dick Hecht said that when he escaped from his home with his wife, "the whole mountain was on fire," and it was so windy he could barely stand.
"It was like a tornado," he said.
The couple tried to return to their home before morning, but they were turned back by high winds and erupting flames. As they made their way back down the mountain roads, flames burned less than 40 yards from their vehicle.
Evacuees could return to their homes at noon Saturday, Reno Mayor Bob Cashell said. A number of local hotel-casinos were also offering discounted rooms to displaced residents.
More than 150 people had filled two shelters set up at area high schools by midmorning.
John and Maggie Givlin were among those watching a television at Reno High School, scanning the screen for details on whether the home they left behind was safe. They already were preparing to flee when a police officer knocked on their door at about 1:30 a.m.
"I looked out the front window and saw the glow over the hill before us," John Givlin said.
He and his wife made their way out of their home with a flashlight. Outside, flames billowed in every direction.
At least 90 schools were closed for the day to clear the roads of school traffic and make way for emergency workers.
More than 4,000 NV Energy customers lost power as poles and electrical wires were scorched and knocked down, said spokeswoman Faye Andersen. Utility workers were not allowed into the fire area.
The U.S. Postal Service suspended delivery to the area for the day, and the state high school athletic association moved its football playoffs from Friday night to Monday.
