The National Weather Service has issued a Flash Flood Watch for the entire listening area until 7am on Monday. In our previous article we talked about storms forming to the west and moving into our general area overnight. The weather service says that the overnight storms may produce heavy rainfall with localized amounts of several inches expected. This may lead to flash flooding, particularly in urban and hilly areas.
Flash flooding will pose a danger to anyone near waterways and low lying areas. It may affect travel as some roads could be flooded.
A flash flood watch means that conditions may develop that lead to flash flooding. It does not mean that flooding has occurred or is.
Thunderstorms producing torrential rainfall have moved into west central and southwest Iowa this evening and will continue to progress east to northeast overnight. Additional storms are expected to develop overnight with the potential for heavy rainfall. Many areas will receive 1 to 2 inches of rainfall with some locations receiving more at a rate of 2 inches per hour as heavier storms moving through.
