Heavy Rain & Flooding

A frontal boundary stalled near the Ohio River during the morning of May 12. This led to numerous rounds of thunderstorms which dropped widespread heavy rain across parts of southern Ohio, southeast Indiana and northern Kentucky. Widespread rainfall amounts in excess of 2 inches were common, with some reports over 3 inches. This same area was hit with heavy rain just a week prior, which made it particularly prone to flooding. Several reports of flash flooding were received including numerous road closures and streams overflowing their banks.
