A flash flood watch has been issued for most of northeast Indiana and northwest Ohio, especially south and east of Fort Wayne, the National Weather Service said today.
Most of the area, including Allen County, has a flash flood watch from 2 p.m. today through Monday morning, the weather service said. Mercer County, Ohio, has a flash flood watch from 2 p.m. today through Sunday morning.
The watch means conditions may develop that lead to flash flooding.
The watch area includes Allen, Adams, Huntington, Wabash, Wells and Whitley counties in Indiana and Defiance, Mercer, Paulding and Van Wert counties in Ohio.
Locally heavy rain in showers and storms today and tonight in those counties may lead to flash flooding, the weather service said. It said a few storms may contain brief gusty winds to 50 mph this afternoon into early tonight, and locally heavy rain in showers and storms continuing through Sunday may lead to flash flooding.
Widespread 2- to 4-inch rain totals are expected in the watch area, and localized spots south of U.S. 24 could receive up to 6 inches, the weather service said. It said a large amount of the rain will run off and cause flooding of streets, fields, lowland areas, streams and creeks; flash flooding could occur, especially in urban areas and in flood-prone spots.
DeKalb, Kosciusko, LaGrange, Noble and Steuben counties in Indiana and Williams County, Ohio, are not included. In those counties, there is a chance of thunderstorms, especially this afternoon into overnight, but severe storms are not expected. There is a chance of thunderstorms there Sunday afternoon.
