In a update late this (Tuesday) morning, officials with the National Weather Service in Des Moines said “MAJOR rainfall likely for many tonight!”  A widespread 2″ to 4″ of rain is likely for much of Iowa. This may lead to flash flooding and river flooding at many Iowa locations this evening into tomorrow morning. Locations from Atlantic eastward could see anywhere from 3-to 5-inches of rain during the period.

Most flash flood fatalities occur at night because people cannot gauge the depth of the water. When in doubt, remember to turn around, don’t drown. A Flash Flood Watch is in effect for all but the far west and southwestern counties in Iowa, from 7-p.m. through early Wednesday morning.
