Flood in Tulsa County, Oklahoma

A vehicle was driven off the road, possibly due to hydroplaning, and down an embankment. The vehicle slid into a flooded culvert and then was washed downstream into a creek. The driver of the vehicle drowned, and was found the next morning in Mingo Creek about 4000 feet downstream from where the vehicle entered the flood water.

Strong to severe thunderstorms developed across eastern Oklahoma during the early afternoon hours of the 30th, to the east of a stationary frontal boundary that was located across north-central Oklahoma into northwest Texas. Moderately strong instability combined with strong wind shear resulted in the development of supercell thunderstorms, which produced multiple tornadoes, including two strong tornadoes, large hail up to half dollar size, and damaging winds. Locally heavy rainfall also occurred across portions of northeastern Oklahoma, which resulted in flash flooding.
