Flood Warning and Latest Update

We are receiving record amounts of rain and flooding. At present, there has been 9" of rainfall in the OKC area. Many streets are closed, including in and out of Will Rogers World Airport. Water rescues are being attempted in several locations. A rescue boat is now at one location where the passengers of the vehicle have been bailing water out with a bucket for the past three hours. Local TV stations are requesting you stay home unless evacuation is necessary. They are preparing to open the flood gates at Lake Overholser, which may cause low lying areas to flood even more.
