When one thinks of tornado season in Iowa, the month of July is not the first thing that comes to mind. The Tornado Outbreak of July 19th will be remembered for quite some time around Iowa. The event started with many photogenic funnel clouds and small tornadoes. Some of these tornadoes did damage in places like Altoona and Bondurant (northeastern suburbs of Des Moines). Larger and more destructive tornadoes followed later in the day with the cities of Pella and Marshalltown taking direct hits. The Pella tornado passed by the KCCI-TV webcam, but the viewing was difficult with the featured image being one of the better views it got. A YouTube timelapse from the webcam is available for your viewing.
