Don’t hit the road until you read this. By Monday evening, parts of Southeast Missouri and Southern Illinois could be underwater—literally. A slow-moving system is set to unleash torrential rainfall across the region, with meteorologists warning of up to 4 inches of rain in just 24 hours. Roads could quickly flood, making everyday drives potentially dangerous and unpredictable.
This isn’t your average rainy day. Forecasters are calling for intense showers and isolated thunderstorms, the kind that dump rain in buckets over short periods. That kind of rapid accumulation is a recipe for flash flooding—especially in places like Cape Girardeau, Poplar Bluff, Sikeston, and nearby Illinois towns that sit near riverbanks and low-lying creeks.
What’s Coming—and When to Expect It
The heaviest rainfall is expected to start late Sunday night and continue into Monday afternoon and evening. Unlike a passing shower, this system is stubborn—it’s dragging its feet, which means the same towns could get soaked again and again by successive waves of thunderstorms.
These storms may park over certain counties, dumping more than an inch of rain per hour. That kind of saturation will overwhelm small creeks, road drainage, and especially those infamous rural Missouri dips and underpasses. The threat becomes even more serious when darkness falls, limiting visibility and hiding flooded spots from unsuspecting drivers.
Where It’ll Hit the Hardest
Southeast Missouri is ground zero for this deluge. Counties like:
-
Cape Girardeau
-
Scott
-
Butler
-
Mississippi
-
New Madrid
…are all in the flood crosshairs. Parts of southern Illinois, especially counties hugging the Mississippi River like Alexander and Union, will also feel the effects.
What You Need to Do Right Now
If you live in or near the flood watch zone, take this seriously. Here’s what officials and weather experts recommend:
-
Stay Off the Roads If You Can: Especially during peak rainfall Monday afternoon and evening.
-
“Turn Around, Don’t Drown”: It sounds cliché, but it saves lives. Even six inches of water can disable a vehicle—or sweep it away.
-
Know Your Routes: If you must drive, plan a backup path that avoids low crossings, creeks, or flood-prone areas.
-
Secure Outdoor Items: High water and winds could move trash bins, lawn chairs, or tools—clogging drains and worsening localized flooding.
-
Keep Your Phone Charged: And turn on emergency alerts so you’re the first to know if the situation escalates.
The Next Threat: Heat After the Rain
Once the rain clears out, it won’t be relief—it’ll be heat. Highs will surge into the upper 80s and low 90s starting Tuesday, with intense humidity making it feel even hotter. Afternoon thunderstorms will remain possible, but the bigger danger may shift to heat exhaustion for those cleaning up or stuck without power.
Final Thoughts
This is shaping up to be a classic Midwest weather punch: flooding rain, sweltering heat, and fast-changing skies. While Monday’s downpour may be temporary, the impact on roads, homes, and day-to-day life could last much longer. Don’t ignore the warnings—prepare now, stay dry, and check in with neighbors, especially the elderly or those living in flood-prone areas.
Bottom line: This is no ordinary storm. It has the potential to trap drivers, flood basements, and create chaos in some of the region’s most vulnerable areas. Keep your eyes on the radar—and your feet out of the water.
