“Historic rainfall” brings “life-threatening” flash floods in St. Louis

Record-high precipitation is soaking St. Louis, leading to what the National Weather Service called “life-threatening” flash flooding. Though no one has been reported dead, authorities said they were carrying out multiple rescues — and photos showed cars almost entirely submerged in the water.

Massive thunderstorms that hit St. Louis overnight prompted a “historic rainfall event,” per the National Weather Service, which in turn caused “widespread flash flooding” throughout Tuesday morning. As of 7 a.m. local time, the city had shattered its daily rainfall record, reporting 8.06 inches of rain in just seven hours, the Weather Service said. The previous record, set in August 1915 after the Galveston hurricane, was 6.85 inches.

The rainfall led the National Weather Service to declared a flash flood emergency for St. Louis early Tuesday morning — which, per the Weather Service, describes the “EXCEEDINGLY RARE situations when extremely heavy rain is leading to a severe threat to human life and CATASTROPHIC DAMAGE from a flash flood is happening or will happen soon.”

“Typically, emergency official[s] are reporting LIFE THREATENING water rises resulting in water rescues/evacuations,” the service added.

Photos shared on social media early Tuesday showed police retrieving a driver from their car around 5:30 a.m., when police said heavy downpours trapped the vehicle on a flooded roadway. The photos showed the water has risen so much that the car’s tires were submerged.

The St. Louis Fire Department said some vehicles were “fully submerged” and that rescue boats had been deployed.

The flash flood emergency remained in effect for hours. During that time, the Weather Service warned residents to avoid driving through flooded roadways. At the time, the water had already partially submerged roadways and residential areas, leading to interstate highway closures and rescue efforts by local law enforcement.

The flash flood emergency has since been downgraded to a flash flood warning, which is currently expected to expire at 11:45 a.m. local time.

The Weather Service emphasized most flood deaths occur in vehicles. “Please turn around, don’t drown!” the agency tweeted, reiterating the slogan used to remind people of the dangers of moving through a flooded area where it’s hard to tell how deep the water is.

Governor Mike Parson echoed that in his own statement on the flooding, writing, “We urge Missourians to continue to follow the safety messaging of local authorities and avoid travel in flooded areas until floodwaters recede. Never attempt to drive in floodwater.”

Residential properties were also impacted. One video, recorded by a resident and shared on Twitter by a reporter with CBS affiliate KMOV, showed the person’s backyard completely inundated with water. A fence and tree trunks appeared to be partially submerged.

The St. Louis Fire Department said it had responded to 18 homes with “substantial flooding/trapped occupants.”

The agency warned that isolated thunderstorms in southeast Missouri and southwest Illinois “may become strong to severe” in the mid-afternoon or evening, with “damaging winds” posing the greatest threats as well as possible hail. The region could also see additional, and potentially severe, thunderstorms later this week.
