Dallas County and the following Iowa counties are affected by the flood watch: Black Hawk, Greene, Humboldt, Marshall, Polk and Tama.
River forecasts include observed precipitation as well as expected precipitation over the next 48 hours, according to the NWS. At this time there is limited confidence associated with rainfall amounts and the location of predicted rainfall.
If rainfall in the basin is less than predicted, the forecast river stage may not be reached. Conversely, if rainfall is more than predicted, the river may crest higher.
As the rainfall forecast becomes more certain, this watch will either be upgraded to a warning or cancelled.
