The multi-day flood outbreak that stretched as far as coastal Maine on Friday has narrowed and reorganized, with 54 active National Weather Service warnings now covering eight states — Iowa, Illinois, Indiana, Kansas, Louisiana, Missouri, Oklahoma, and Washington — as the event’s center of gravity shifts firmly to the central and southern Plains.
The alert count is essentially unchanged from Friday’s 55, but the geography has moved significantly. Maine, which entered the warning zone for the first time in this outbreak on Friday, is no longer on the active list. In its place, the pattern has tightened around a concentrated corridor running from the Kansas-Missouri border south through Oklahoma and into Louisiana’s Gulf Coast fringe.
In eastern Kansas, the National Weather Service has active warnings through Sunday morning spanning more than a dozen counties, including Johnson, Leavenworth, Wyandotte, Shawnee, Douglas, Lyon, Osage, and Wabaunsee. Excessive runoff is expected to affect rivers, creeks, and low-lying areas throughout the region. Across the state line, Missouri warnings remain dense, covering Jackson, Clay, Platte, Cass, Lafayette, Bates, Henry, Pettis, and Johnson counties, among others — placing residents near Kansas City weather at the heart of the most active cluster in the current event.
In south-central Iowa, flooding is no longer a future threat — it is ongoing. The National Weather Service confirmed early Saturday that roads in Mahaska, Marion, and Monroe counties remained closed due to flooding, with warnings valid through 9 p.m. CDT Saturday. Rivers, creeks, and streams in the area are actively overflowing.
The outbreak’s southern reach has extended visibly in the past 24 hours. Eastern Oklahoma — including Rogers, Wagoner, Cherokee, Delaware, Nowata, and Craig counties — is now squarely in the active warning footprint. Calcasieu Parish in southwestern Louisiana marks the event’s southernmost active alert, connecting the outbreak to the Gulf Coast for the first time this cycle.
Residents across Shawnee County and surrounding areas, including those in Topeka weather, face flash flood risk through Sunday morning as additional runoff accumulates on already saturated ground.
The National Weather Service urges residents to monitor updated local forecasts and be prepared to act if warnings are upgraded. The agency’s standing guidance applies broadly: turn around, don’t drown when encountering flooded roads. Most flood deaths occur in vehicles.
Warnings across Kansas and Missouri are currently forecast to persist through Sunday morning. Residents should consult their local National Weather Service office for the latest river and stream conditions.
