Widespread heavy rainfall from 8 to 14 inches occurred during the last week of April. At the Carbondale airport, a rainfall total of 11.01 inches was measured from April 22-30. This excessive rainfall caused most creeks and streams to flood for an extended period of time. Some of the flooding was major. A disaster proclamation was issued by the governor of Illinois due to the damage from flooding and severe storms. The National Guard was deployed to assist with sandbagging and other operations.
