When lightning is detected within a pre-defined radius of the Alexandria, Va. club, a siren will sound one long horn blast and a strobe light will flash—meaning it is unsafe to be outdoors and seek shelter immediately. Three short horn blasts will sound an all-clear alert when it is safe to resume outdoor activities.
Mount Vernon Country Club has deployed Earth Networks Sferic Siren at its golf course in Alexandria, Va. In 2019, Earth Networks detected 4,924 lightning strikes in Alexandria and neighboring Fairfax County. Mount Vernon Country Club is now equipped with an advanced warning system to detect nearby lightning, enabling staff to enhance member and guest safety by better managing weather threats.
When lightning is detected within a pre-defined radius of the club, the system will sound one long 15-second horn blast and a strobe light will flash. This means it is unsafe to be outdoors, and people in the vicinity must seek shelter immediately. When the area is under alert, the strobe light will continue to flash. Three short 5-second horn blasts will sound an all-clear alert when it is safe to resume outdoor activities.
The Earth Networks Sferic Siren is an automated system that sounds a high-decibel horn and activates a bright strobe light, alerting staff and visitors to seek shelter when lightning is detected in the area and easing the burden from citizens to make difficult decisions when lightning is an imminent threat. Sferic Siren is powered by Earth Networks’ Total Lightning Network (ENTLN), the world’s largest lightning detection network with more than 1,800 sensors in more than 100 countries.
