The ongoing flooding tormenting the Midwest and nearby states, has its origins in a series of unusual and recording setting weather events impacting Iowa and the Midwest.

University of Iowa assistant research engineer, Antonio Arenas with the help of his colleagues at IIHR Hydroscience & Engineering and the Iowa Flood Center created an easy to use digital timeline that describes extreme weather events that have occurred in the Midwest over the last year and their impact on Iowa. 

The timeline starts with the months of June and July 2018 as being months with above-average rainfall. Arena also documents record Iowa rainfall in the fall of 2018, as well as the heavy snowfall in the Midwest this past winter and how it all has contributed to record flooding in Iowa this spring.

Antonio Arenas states that these weather events are noteworthy and for some, are record setting. However, he also believes it is equally important to note that all of these weather fluctuations had all occurred within a 12-month window. 

The digital timeline offers information on the past 12 months of extreme weather events such as the Polar Vortex, extreme precipitation, a rare bomb cyclone, ice dams, heavy snowfall, frozen ground, and more.

Arena invites people to click through the animated slides, videos, maps, satellite images, and brief descriptions to see how these recent extreme weather events have impacted Iowa and the Midwest.
