Abstract

August 2007 experienced record - setting rains in northern Illinois as the result of a per - sistent weather pattern. Northeastern Illinois received 11.61 inches, the highest August ra infall since 1895. Northwestern Illinois received 7.83 inches, the fifth highest since 1895. At least 35 sites received 10 inches or more of rainfall. These particular sites expe - rienced either their wettest or second wettest August on record. The site wit h the most August rainfall was Genoa, Illinois, with 16.56 inches. Record rainfall, high winds, and high river levels over a densely populated area of the state combined to produce at least $353 million in losses in August. Most of the losses stemmed from the August 23 - 24 storm event. Insured losses from that one event were $213 million from personal prop - erty, commercial, and crop losses. The utility, transportation, and government sectors experienced additional losses of $115 million.
