...FLOOD WATCH REMAINS IN EFFECT THROUGH LATE TONIGHT...

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

* WHERE...Much of central Iowa.

* WHEN...Through late tonight.

* 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...
  - Flooding is currently occurring in a few areas. Though rain has
    mostly come to an end, rivers may continue to rise throughout the
    day. Poor drainage and low lying areas may experience ponding.

    Significant rises are expected or ongoing on many rivers and
    streams, which may exceed flood stage. Of most concern include
    but are not limited to portions of the following river basins...
    South Skunk from Ames downstream, Des Moines from Des Moines
    downstream, Raccoon downstream of U.S. Hwy 30, as well as the
    Middle, South and Grand.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

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.
