Centerville, Iowa – Torrential rain continues to pound southern Iowa early Sunday, with flash flooding possible in Wayne and Appanoose counties until at least 10 a.m.
According to the National Weather Service in Des Moines, a Flood Watch remains in effect as rounds of slow-moving thunderstorms deliver intense rainfall rates of 1 to 2 inches per hour. Some areas could see totals between 2 and 5 inches, with isolated pockets surpassing that mark.
Residents in Centerville, Corydon, Seymour, and surrounding towns should be alert for rising water on rural roads, low-lying areas, and small creeks. Urban flooding is a growing concern, especially in areas with poor drainage. Emergency responders urge drivers to avoid flooded roadways, as just 12 inches of moving water can sweep away most vehicles.
Storm drains and culverts may quickly become overwhelmed. Those in flood-prone zones should move valuables to higher ground and monitor NOAA weather radios or local alerts for real-time updates.
The heaviest rain is expected to taper mid-morning, but saturated soil could prolong the flood threat. Additional warnings may follow if rain bands stall or strengthen.
