Lightning detector installed on campus

We are excited to announce that Admiral Farragut Academy has purchased the THOR GUARD Lightning Prediction System. This warning system will assist in ensuring the safety of our students, faculty, and staff campus-wide when inclement weather or lightning is in the area. View the current status of the system at

The system is located near the concession stand and will go off when there is lightning within six miles of the school. You will hear a siren and the yellow light will be flashing on the concession stand. When this siren goes off, everyone on campus is instructed to stay inside. When the lightning has stopped, the siren will go off three times to alert everyone that we are all clear and safe.

More About the Product & How It Works

The THOR GUARD Lightning Prediction System has been manufactured in South Florida since 1976. Over the ensuing years, representing literally millions of hours of accurate and safe operations, THOR GUARD has consistently proven its reliability. 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. Lightning “detection” systems require the occurrence of an actual lightning strike before a warning is given. Many times this is just too late.

THOR GUARD is the only stand-alone lightning warning device used at all National Championships conducted by the United States Golf Association, the Canadian and European Golf Tours and many local sections of the PGA of America. We are the choice of Marriott Golf, the PGA Tournament Players Clubs, ABC Television Sports, and the Atlanta Summer Olympics. THOR GUARD is also highly regarded and utilized by many non-golf industries as well. Some of our significant customers include American Airlines, Delta Airlines, Air Canada, United, Fed Ex, UPS, Freeport McMoRan (FMI) Mining, BHP Billiton Mining, Shell Oil, ATF, US Marine Corps, US NAVY, US ARMY, Motorola, AT&T, and over 700 universities, schools and municipalities. From airports and ski areas to the NFL and zoos, THOR GUARD can be found providing on-site, real-time lightning prediction and warning.

Thor Guard Hazard Levels:

  • All Clear: There is no significant energy. This will generally indicate a safe environment.
  • Caution: Normal atmosphere energy shifts are occurring and depending on the situation, may increase to a Warning.
  • Warning: A significant amount of energy has moved into the area being monitored. Depending on the storm, it may pass by without achieving a RED ALERT level.
  • Red Alert: The conditions for a local strike are prevalent. Activities should cease and seek immediate cover.
When a Red Alert hazard is reached at the station, a horn will sound continuously for 15 seconds. The strobe light will turn on and stay on. Upon returning to a safe environment, the All Clear signal will sound; 5 seconds on, 2 seconds off, repeated two more times. The strobe light will turn off.
