...FLOOD WATCH REMAINS IN EFFECT THROUGH LATE THURSDAY NIGHT...

* WHAT...Flooding caused by excessive rainfall continues to be
  possible.

* WHERE...Much of central Iowa.

* WHEN...Through late Thursday night.

* IMPACTS...Excessive runoff may result in flooding of rivers,
  creeks, streams, and other low-lying and flood-prone locations.
  Area creeks and streams are running high and could flood with more
  heavy rain.

* ADDITIONAL DETAILS...
  - A prolonged period of moderate to heavy rain is forecast through
    Thursday evening. It will be falling on already saturated soils.
    Rainfall totals will range from 2 to 4 inches in a southwest to
    northeast oriented band across central Iowa, with locally higher
    amounts likely. This rainfall may lead to flash flooding. Poor
    drainage and low lying areas may experience ponding.

    Significant rises are expected on many rivers and streams, which
    may exceed flood stage. Some larger river basins of most concern
    include the South Skunk River basin from Ames downstream, the Des
    Moines River basin Des Moines downstream, the Raccoon River
    downstream of U.S. Hwy 30, as well as the North, Middle, South,
    Nishnabotna, Grand and Chariton River basins.
