LIGHTNING DETECTION SYSTEMS
Center Grove invested in two "Thorguard" lightning detection systems to protect students, staff, and visitors to all of our campuses.Both systems include a sensor that scans a 2.5 mile radius in the sky for the potential to produce lightning. If a lightning threat is detected, a strobe flashes and an air horn sounds. The tone is 113 decibels and sounds for 15 seconds. Click this link to hear the horn at Middle School North. The strobes continue to flash until the threat has dropped below the danger threshold for five minutes. At that time, the horn will sound again to give the all clear.
The Thorguard systems went online for Center Grove on March 1, 2015.
