Thor Guard is a computerized system that can predict the probability of a lightning strike within 8-20 minutes before it will strike. The system is 97% accurate within a 2 â€“ mile radius. When there is a potential for a lightning strike within the coverage area, a strobe light will turn on and a warning horn will sound with an uninterrupted 15-second blast. Immediately upon hearing or seeing these signals park users must leave and seek appropriate shelter. When the system senses conditions are safe, the strobe light will turn off and the horn will sound three short four-second blasts. Then normal activity may resume. The system operates 8 a.m. â€“ 11 p.m. seven days per week March â€“ November.
