Meteorological Factors Leading up to the Flood of 2008

 The culmination of many above normal to record meteorological factors, from the winter of 2007-2008 through the spring of 2008, led to the historic Midwest Flood of June 2008. Locally this flood might be most remembered for its devastating impacts in the Cedar Rapids, Iowa City, Oakville, and Gulfport areas.

 

 Key Contributing factors to the Historic Flooding of 2008:

 Heavy winter snow (from late 2007 through early 2008)

+ Significant flooding in April 2008 (resulting in high river levels)

+ Extremely moist soils (continuing through May)

+ Heavy June rains
