The Flood Watch has been extended through 1 PM for most of eastern Iowa and portions of northwest Illinois. More rainfall this morning on top of the very heavy rainfall that occurred overnight, may aggravate any ongoing flooding situations or produce new ones. Urban areas, poor drainage locations, and areas with recent heavy rain are at greatest risk for flash flooding. Several area creeks and rivers will also continue to experience significant rises and flooding today.
Rounds of recent heavy rain and run-off will produce significant rises on several area tributary rivers, and even portions of the main stem Mississippi River through the upcoming week. Some of the rivers will go into flood, including portions of the Mississippi River from the Quad Cities on southward.
With heavy rainfall expected at times into Sunday, here are some tips for safe driving in the heavy rain. Make sure to slow down, increase following distance, and turn on your low-beam headlights to improve visibility. Stay alert! Stay safe!
