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. In addition, poor drainage and low lying areas
may experience ponding. All this rainfall will cause rises on
area rivers, which may exceed flood stage in at least a few
locations.
