A slow moving storm system will lift northeast across the upper Midwest through Monday. This system has a rich moisture supply and has already dropped one to three inches of rainfall across portions of central Iowa with an additional inch or more expected.
A flood watch will be in effect from 4pm this afternoon through Monday morning. One to three inches of rain has fallen over the watch area. An additional one inch to an inch and a half is expected.
Excessive rainfall has already filled ditches and saturated the soil. In addition, rivers and small streams are expected to rise. The expectation of an additional inch to an inch and a half of rain today and tonight may lead to ditches overflowing and rivers going above flood stage.
A flood watch means there is a potential for flooding based o current forecasts. You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.
