The Thor Guard equipment is lightning "prediction" technology that measures the likelihood of lightning even with no visible evidence of a lightning flash. This is different from "detection" technology that responds to flashes of lightning in the distance. Please note this is not "protection" technology. The Thor Guard equipment does not attract or absorb lightning strikes - it intended service is to provide an early warning.
Essentially the way it works is there are rooftop sensors that monitor atmospheric conditions around the clock. When the sensor determines that the likelihood of lightning strike exceeds a 30% chance, the sensor emits a radio signal to remote horns and strobe lights installed at the park sites throughout the Village.
The following procedures are to be followed when potentially dangerous weather exists:
Warning Signal - A warning signal (one long 15 second horn) will sound and strobe lights will activate when a potentially dangerous weather situation is approaching.
Procedures - All activities in the park should end immediately and patrons should leave the park. It is recommended that park patrons seek shelter in their cars or a building. All park patrons should wait until the lightning prediction system performs an All Clear Signal before returning to the park.
All Clear Signal - The All Clear Signal (three short horn blasts, two seconds apart) will sound, and the strobe lights will deactivate. After the All Clear Signal sounds and the strobe lights deactivate, park patrons may resume their activities.
Caution - The Thor Guard System helps assess the conditions. Neither the signal nor the system it intended to guarantee that conditions are safe. If the weather is threatening and no warning signal is heard or seen, use good judgment and clear the field. Do not wait for the warning signal to activate, as the system can malfunction.
