Understanding the Thor-Guard Siren

The Thor Guard Lightning Prediction System is provided and maintained by the Park Ridge Park District. Thor Guard consists of sensors within the City of Park Ridge that measure electrostatic charges at ground level and in the atmosphere. When conditions indicate that a lightning occurrence is probable, alarm horns provide an 8-12 minute warning to clear areas and seek shelter.

Warning Horn will sound a 15 second blast when a potentially dangerous weather situation is approaching. Clear the area immediately and seek proper shelter. Wait for the All Clear (three short blasts) to resume activities.

The alarm horns are at Maine East High School, North Park, Northwest Park (Franklin School), Oakton Pool, Woodland Park, Ni-Ridge Park, Jefferson/Emerson School site, Hodges Park, Northeast Park (Field School), Maine Park, Carpenter School, Hinkley Park, Centennial Park (Lincoln/Washington Schools), Maine South High School, South Park (Roosevelt School), Jaycee Park, Brickton Park and Southwest Park.
