The Thorguard Lightning Prediction System was installed in the parks to warn patrons of the dangers of lightning. When the 15-second warning horn sounds you should:

1. Clear the park immediately or seek proper shelter.
2. Do not return to the park or move out of the shelter until 3 short horn blasts sound. This is the all clear sound.
3. In the all clear sound does not sound after 30 minutes, dangerous weather is still in the area and the activity should be canceled.
4. Stop and see shelter anytime you believe lightning threatens you, even if a signal has not sounded.
