Niles Park District has installed a lightning warning system for your protection. Lightning is a severe hazard that must be viewed seriously. Everyone should immediately seek shelter any time they believe lightning threatens them, even if a signal has not been sounded.

When lightning is imminent, a SINGLE 15 second blast of the horn will sound at each Thor Guard location. A strobe light will begin flashing and remain flashing until safe conditions return. Whether you are in a park owned location or your own yard, please seek shelter. When the danger has passed, you will hear THREE, short 5 second blasts and the strobe light will go off. At that time you may return to outdoor activities.

The system will be in operation from April to November, seven days a week from 6:00 a.m. to 10:00 p.m. In order to keep the entire system operational, we will test all locations once a month. Every 4th Thursday of the month at 10:00 a.m. the “All Clear” THREE short blast sequences will be manually activated, unless there is potential of dangerous weather approaching.
