The Village of Orland Park utilizes a network of lightning detection monitors to enhance safety at parks, athletic facilities, and outdoor recreation areas. These systems provide real-time alerts when lightning is detected nearby, allowing for timely evacuation and risk reduction.

System Locations

The Village currently operates 5 lightning detection monitors at the following locations:

• Cachey Park

• Centennial Park Baseball Fields

• Centennial Park Aquatic Center

• John Humphrey Complex

• Schussler Park

How the System Works

The Village uses the iStrike Lightning Detection System, which relies on a network of ground-based sensors to detect lightning in real time.

• Sensors detect electromagnetic signals produced by lightning strikes

• Data is processed through software to determine strike location

• Triangulation is used to accurately track storm activity

• The system automatically triggers alerts when lightning enters a defined safety radius

This combination of hardware sensors and software-driven analysis allows for fast, reliable detection and notification of hazardous conditions.

When Alerts Activate

Parks & Athletic Facilities

(John Humphrey Complex, Schussler Park, Cachey Park, Centennial Baseball)

• 10-mile radius:
  • Siren and red strobe activate
  • Evacuation is required

Centennial Park Aquatic Center

• 15-mile radius:

  • Red strobe activates

  • Early warning only – no evacuation required

• 10-mile radius:

  • Siren activates

  • Evacuation is required

What Happens During an Alert

When lightning is detected within the activation radius:

• A red strobe light begins flashing

• A loud siren sounds (similar to a police-style siren, not a tornado siren)

• The system provides a clear, immediate warning to all individuals in the area

What You Should Do

If you are near a facility when the system activates:

• Immediately stop activities

• Move to your vehicle or a safe enclosed space

• Remain sheltered until the system indicates it is safe

The Village follows a standard protocol where individuals should stay sheltered until the “all-clear” siren sequence is completed.
