Field Conditions

IMPORTANT FIELD INFORMATION

Field information will be updated Monday through Friday on our web site and the hotline (630-293-6325) by 3pm. We will not give field information prior to 3pm. Please refrain from calling our office at 10am to find out if fields are open or closed. Often, a thunderstorm at 11am does NOT result in a field closure. The Superintendent of Parks along with the Athletic Supervisor check fields daily and report conditions to our office by 3pm. Additionally, an open field at 3pm can become a closed field at 5pm due to severe weather. If at anytime during the course of a game severe weather occurs the Umpire and Park District Staff located at the fields have the final say on field closures.

Thor-Guard is an integrated lightning prediction and warning system. Thor-Guard uses a highly sophisticated sensor and computer to measure and analyze the electrostatic field in the atmosphere. Lightning originates within this field, thus allowing THOR GUARD to make calculations predicting its occurrence, even though there may be no visible evidence of lightning. When lightning is detected you will hear one loud warning horn at that time you should seek cover immediately. When it is clear to return to the open areas of the park Thor-Guard will sound 3 (three) consecutive warning horns.
