The "Ivan" Flood Event of September 17th - 18th, 2004


The above image depicts storm total rainfall (in inches, as estimated by National Weather Service Doppler Radar) from 2pm on Thursday, September 16th through 3pm on Saturday, September 18th, 2004.  Most of the rainfall shown above fell between 8am Friday, September 17th and 8am Saturday, September 18th.  The rainfall was caused by moisture from the remnants of Hurricane Ivan interacting with a frontal boundary. The legend is located at the top-left portion of the image.  The widespread 3 to 5 inch rainfall totals produced major flooding at several river points.  Some points had their highest river stages since the January 1996 flood.  Below is a summary of flood reports and rainfall amounts collected from spotters and National Weather Service gages:
