Aug 19, 2011
Between five and seven inches of rain fell over Ottawa County, with the highest amounts in Port Clinton. The rain fell as a result of an area of low pressure moving over the lakeshore, producing onshore winds out of the northeast. With water temperatures near 80 over Lake Erie any convection was able to support torrential rain. A line of storms moved over Ottawa County for about five hours, overwhelming drainage systems.
