Though rain has moved into the forecast, wildfires are still a real threat as Oklahoman prepare for the Thanksgiving holiday.On Tuesday, close to 20 homes had to be evacuated in Canadian County after large grassfires burned nearby.KOCO 5 spoke with the fire crews on Wednesday about how Oklahomans can help fight this danger. Fire officials say that it is all about being prepared and keeping any items, such as leaves, out of the yard.On Tuesday, flames made their way through thick brush in Canadian County. Nearby, families who were in several homes in the path of the fire were forced to evacuate.Fire officials said that the fire was caused by sparks from a welding crew."All it takes is a spark at that point and you can have a pretty devastating wildfire that can threaten not only acreage and livestock but also many different homes," said Chief Benny Fulkerson of the OKC Fire Department.No homes were burned this time."So again, the ‘it’s not going to happen to me’ philosophy isn't true. It happened to a bunch of people already this month," Fulkerson said.It’s important to do your part to prevent homes from catching fire. Keep grass cut short and irrigated, keep trees trimmed, and keep yards clean and free of debris, especially from dry leaves."You have the high winds, the low humidity, of course, the dormant vegetation. The only missing ingredient is that spark," Fulkerson said.
