Wider weather episode

During the early morning hours of July 19th a dissipating storm complex over Michigan reintensified as it moved over Lake Erie. These strong storms produced a narrow swath of 3 to 6 inches of rain fell over north central Ohio. The rainfall rates of around two inches per hour produced significant flash flooding. The most severely effected areas were Cuyahoga, Summit, Medina, and Stark Counties. The flooding was caused by runoff from torrential rainfall that exceeded the capacity of the small streams and storm water systems of several communities. Water depth in the flooded areas was 1 to 3 feet deep, enough to fill basements and inundate the first floor of hundreds of homes and businesses. Despite being located on a hill, the Akron-Canton airport flooded due to the intensity of the rainfall.
