The Cary Park District utilizes the Thor Guard Lightning Prediction System at Cary-Grove Park, Hoffman Park, Jaycee Park, Kaper Park, Lions Park, the Community Center, and the Foxford Hills Golf Club. The system helps alert park users to hazardous weather conditions.
The system is operational between 7:00 am – 10:00 pm from
April 1 – November 15.
When a lightning threat is detected:
- The system will give one 15-second blast and/or strobe light flashes
- Park users should clear the area immediately and find appropriate shelter
When the lightning threat has passed:
- The system will give three 5-second horn blasts and/or strobe light stops
- Park users can resume all outdoor activities
The Thor Guard system does not guarantee weather conditions are safe for outdoor activities. If you see lightning or hear thunder, even if the alarm does not sound, potentially dangerous weather is approaching.
Park users should clear the area and return 30-minutes after the last occurrence.
Watch for signage in the parks and outside of the facilities that have the lightning predication system installed for more information.
