St. Louis, MO – Residents across the Central and Southern Plains into the Mississippi Valley should prepare for heavy rain and possible flash flooding on Tuesday, September 23, according to the National Weather Service’s Weather Prediction Center (WPC).
The WPC issued a Slight Risk of Excessive Rainfall, meaning scattered flash flooding is possible. A mid- to upper-level disturbance is expected to trigger showers and thunderstorms across the region, with rainfall totals projected between 2 to 4 inches, and locally higher amounts in some areas.
According to forecasters, the greatest impacts will be felt in parts of Missouri, Arkansas, Oklahoma, Kansas, and surrounding states. The heavy rainfall could quickly overwhelm drainage systems, leading to dangerous road conditions and localized flooding, particularly in low-lying areas.
The WPC cautions that even a “slight” designation warrants attention. “Given the volume of rainfall expected, this could result in scattered flash flooding, especially in the Slight Risk area,” the agency stated.
Officials urge residents to stay weather-aware, ensure they have multiple ways to receive emergency alerts, and avoid flooded roadways. The National Weather Service repeated its common warning: “Turn Around, Don’t Drown.”
Communities in the flood risk zone should expect potential travel delays, hazardous driving conditions, and possible disruptions to outdoor activities throughout Tuesday.
