A Flood Watch remains in effect across central and southwest Ohio, with forecasters expecting 1 to 2 inches of rainfall and localized totals up to 3 inches before the rain tapers off later on Thursday. Transportation officials warn that water could collect along low-lying roadways and underpasses, especially in flood-prone areas near streams and drainage channels.

Why it matters

Heavy rainfall can quickly lead to dangerous flash flooding, especially in urban areas with poor drainage. Flooded roads pose a serious risk to drivers and can disrupt commutes and other travel in the affected regions.

The details

According to the National Weather Service, the Flood Watch includes major metro areas such as Columbus, Cincinnati, Dayton, and Springfield, along with dozens of surrounding communities. Counties along the Scioto, Little Miami, Great Miami, and Ohio River basins may see creeks and tributaries rise quickly if heavier downpours develop overnight.

  • The Flood Watch remains in effect through Thursday afternoon.
  • Forecasters expect the heavy rain to taper off later on Thursday, but elevated stream levels may persist through the afternoon.
