Overview
At 504 AM CDT, Doppler radar indicated a large area of light to moderate rain was occurring across the warned area. Heavy rain producing storms earlier brought rainfall of 2 to 5 inches across the warned area. Flash flooding is either ongoing or expected to begin shortly due to runoff from the earlier heavy rain combined with the steady rain falling.
Hazard
Flash flooding caused by thunderstorms.
Source

Some locations that will experience flash flooding include... Cedar Rapids, Anamosa, Vinton, Marengo, Mechanicsville, Stanwood, Marion, Hiawatha, Mount Vernon, Robins, Belle Plaine, Center Point, Lisbon, Fairfax, Solon, Ely, Atkins, Walford, Springville and Palo.
