Thor Guard is a lightning prediction and warning system installed in April 2022 at Kingston Park.
The Thor Guard system uses sensors that detect and predict lightning. The city received a grant to purchase much of the equipment for the park, which hosts thousands of people at various events all year.
The Thor Guard sensors are connected to clusters of horns located throughout the park. Whenever lighting is detected, the horns sound an alert to staff and visitors. The horn clusters also contain strobe lights for lightning and two levels of heat warnings, which can help players avoid heat-related conditions like dehydration and heatstroke. Thor Guard analyzes a storm's strength, speed, and intensity to determine when the system issues an alert and the subsequent all-clear to people at Kingston Park.
If you live near the park, you may hear the sirens sound during a storm or when the system is being tested. You do not need to take action when you hear the horn; it is strictly to alert people at the park that they need to clear the area due to unsafe conditions.
