The City of Troy Recreation Department and Parks Department have installed a ThorGuard Lightning Prediction System at Duke Park. The system will provide horn and light signals to indicate dangerous weather conditions.
When a lightning strike is imminent within a five-mile area of Duke Park, the system sounds a 15-second horn blast, and strobe lights are activated until the threat of lightning has passed. Activities may resume after three five-second blasts of the horn are sounded and the strobe lights stop flashing.
The system was budgeted at a cost of $21,885, and was paid for out of the Recreational Programming Fund.
