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.
