Thor Guard Lightning Prediction System

The Hoffman Estates Park District utilizes the Thor Guard Lightning Prediction system at our facilities and parks. The system helps alert patrons to hazardous weather conditions.

One 15-second blast signals a potentially dangerous weather situation approaching. Clear the area immediately and find appropriate shelter.  3 short blasts signals all clear, safe to return. If you see lightning or hear thunder, even if the alarm doesn’t sound, potentially dangerous weather is approaching. Clear the area and return 20 minutes
after last occurrence.
