The Mississippi River has crested at numerous hardest-hit towns, but with more heavy rain expected over the next several days, the latest round of spring flooding may be far from finished.

The river crested Monday in downtown St. Louis and will do so later this week farther south.
The floods are blamed on four deaths, three in Missouri and one in Indiana.
Flood gates have closed as the Mississippi River continues to swell. The Mississippi River initially reached that risky height due to a mix of rain and melting snow that caused all of the rivers in the system to crest at the same time.
