Flash Flood in Comanche County, Oklahoma

Numerous relayed images and videos showing extensive flash flooding in and around the community of Lawton. Multiple water rescues were performed, and multiple vehicles were stranded in floodwaters. A man drowned when his vehicle became submerged in floodwaters near the intersection of 2nd Street and F Avenue. Event time is approximate.

A slow-moving mesoscale convective vortex (MCV) produced severe weather and flash flooding during the morning and afternoon of the 26th. An initial complex of thunderstorms across southwestern Oklahoma and western-north Texas produced reports of thunderstorm wind damage and large hail, especially with a supercell thunderstorm that moved near the city of Lawton. Areas of persistent heavy rainfall also led to flash flooding across this area, with a flood-related fatality occurring in Lawton as a motorist drove into flooding beneath an underpass. By the afternoon, as the broader convective vortex moved eastward and instability developed, additional thunderstorms developed across southeastern Oklahoma. A few of these thunderstorms, exhibiting brief supercellular characteristics, produced hail and a tornado as they interacted with a remanent surface boundary across the area.
