Wild fires. Current reports are some as big as 1 mile wide. These are inside the city limits. High winds, dry temperatures fuel wildfires across Oklahoma By The Associated Press A rash of grass fires broke out Sunday afternoon throughout the Oklahoma City area, fueled by unseasonably dry conditions and wind gusts of more than 50 miles per hour. Oklahoma City firefighters responded to at least 15 grass fires in the metro area Sunday afternoon that burned more than 100 acres, said Oklahoma City Fire Major Brian Stanaland. A few homes suffered minor exterior damage in northeast Oklahoma City after some power lines arced and caught some grass on fire. While firefighters battled that blaze, high winds blew up some construction material from a nearby construction site that hit the power lines, caught on fire and landed on a nearby nursing home, Stanaland said. "You basically had flying, flaming debris," Stanaland said. "Luckily, we were already on the scene putting out the fires when it happened so we were able to put it out. We were very, very lucky." No injuries or major structure damage were immediately reported in Oklahoma City. Another large grass fire was reported near Guthrie that forced the closure of both the north and southbound lanes of Interstate 35 for more than an hour, said Oklahoma Highway Patrol Trooper Pete Norwood. State Highways 33 and 105 near Guthrie remained closed Sunday afternoon because of smoke that limited visibility, Norwood said. A grass fire also was reported near Bristow in northeast Oklahoma and another near Wellston in Lincoln County that threatened about 30 homes, said Michelann Ooten a spokeswoman for the Oklahoma Department of Emergency Management. Meanwhile, firefighters and state emergency officials across the state continued to monitor areas Sunday that were scorched by wildfires over the weekend, while urging Oklahomans to comply with the statewide burn ban. The major hot spots were in Bennington, Bristow and Pink, where grassfires charred hundreds of acres on Saturday, Ooten said. "We are reminding the people that they should be extremely careful in any outdoor activity today," she said. "And remember that any firework activity is illegal, and taking a chance means putting Oklahomans, their homes and firefighters at risk." High winds, record-high temperatures and drought-like conditions across much of the state increased the fire danger to critical levels. "Weather conditions are gearing up," Ooten said. "We're working with military departments to make sure they have supplies on standby, and we are still receiving firefighters from Alabama and Tennessee." Oklahoma has been locked in a dry spell, with winds easing at night and in the morning and then increasing in the afternoon. Dozens of fires began in the state Tuesday when winds gusted to more than 40 mph. The state is more than a foot behind its normal rainfall of about 36 inches for this time of year. Officials declared a state of emergency for Oklahoma Friday because of wildfire conditions, sought a federal disaster declaration and enlisted firefighting help from other states. The wildfires in the last week have ravaged more than 30,000 acres, destroyed nearly 100 homes and businesses, left one man dead and caused a handful of minor injuries.
