Heavy rain bands sweeping across eastern Missouri Thursday have pushed rivers and creeks past their banks, triggering flash-flood emergencies and multiple tornado warnings across the St. Louis metro area. Meteorologists at the National Weather Service in St. Louis expanded a Flash Flood Warning through tonight after Doppler radar estimated 3–5 inches of rainfall in just a few hours, saturating ground that is already water-logged from earlier storms. The agency is urging residents in low-lying neighborhoods and along tributaries of the Meramec and River des Peres to be prepared for rapid water rises and to move to higher ground immediately. Impacts on travel and infrastructure • MoDOT has closed portions of I-55 near Lindbergh Boulevard and several feeder roads where water is overtopping lanes. Commuters should expect significant delays on I-44, I-64 and surface routes into downtown as first responders divert traffic. • Metro Transit has suspended service on parts of the Red and Blue light-rail lines because floodwaters are encroaching on track beds. Riders should check real-time alerts before heading to stations. • Lambert International Airport remains open, but airlines have canceled or delayed more than 60 flights as thunderstorms repeatedly back-build over the terminal corridor. Tornado threat not over While flooding is the immediate hazard, embedded super-cells within the slow-moving frontal boundary continue to spin up brief tornadoes south and east of the city. A Tornado Watch remains in effect for 24 counties in Missouri and Illinois until 10 p.m. CDT, and storm spotters have already confirmed at least two land-spout touchdowns near Arnold and Festus that damaged outbuildings and toppled trees. Forecast and outlook The stalled boundary is expected to sag only slightly southeast overnight, with another 1–2 inches of rain possible before daybreak. Skies gradually clear Friday afternoon, but runoff flowing downstream could keep some creeks at or above flood stage into the weekend. Residents along the Meramec River basin, especially in Valley Park and Fenton, should monitor updated crest projections. Safety checklist • Never drive across a flooded roadway—just 12 inches of moving water can carry away most cars. • Keep phones charged and have flashlights ready in case of power outages. • If a Tornado Warning is issued, move to an interior room on the lowest floor and avoid windows. • Sign up for local emergency alerts and have a NOAA Weather Radio on hand for overnight notifications. With summer events like the Gateway Arch Riverfront concerts scheduled for this weekend, city officials say final decisions on postponements will hinge on Friday’s damage assessments and river level forecasts.
