DALLAS – Another round of severe weather and torrential rainfall rolled through the southern Plains on Wednesday, causing deadly flooding and dozens of reports of damage.

Deputies in Pottawatomie County, outside of Oklahoma City, reported a driver was swept away by fast currents and a responding deputy required assistance due to the strong current.

A similar situation was reported in nearby Lincoln County where first responders said one person was dead following a crash.

The renewed storm threat Wednesday came after at least three people were killed and hundreds of thousands of people were left without power after a serial derecho tore across communities from the Plains and Midwest to the Northeast on Tuesday.

Flooding was reported in the Oklahoma City area on Tuesday night, and officials were forced to close a section of Interstate 35 because of water on the roadway.

NOAA’s Weather Prediction Center (WPC) placed a large area of Texas, Oklahoma and Arkansas in a Level 3 out of 4 risk for flooding on Wednesday, but with more precipitation on the way, it is unlikely that the flood alerts will be discontinued anytime soon.

Officials in Pottawatomie County alone reported more than 30 roadways were shut down, with damage assessments that would likely take days to complete.

Further south in the Lone Star State it was hailstones and winds that were problematic, with gusts approaching 100 mph in severe storms.

Video from Mabelle, Texas, captured the moments a driver crawled out of a semi-truck during the severe weather.

Fortunately, no major injuries were reported to the Storm Prediction Center, but power outages climbed to nearly 100,000 throughout the southern Plains.  

Rainfall not over yet for region

As long as frontal boundaries find their way into the southern Plains and the Mississippi Valley, the chance of scattered showers and thunderstorms will continue to persist into the early weekend.

Forecast models indicate an additional 1-4 inches of precipitation could fall over the Red River Valley through the early weekend.

Most storms are expected to remain below severe weather criteria, but a few could produce hail, damaging winds and isolated tornadoes.

Due to the continuing threats posed by the heavy rainfall, more than 5 million residents across the region were under various flood alerts, which could run through Saturday for some communities.

According to NWS forecasters, just 6 inches of fast-moving water can knock an adult off their feet and a foot of floodwater can carry a car away.
