Alleghany Park Lightning Detection System
Alleghany Park is equipped with a lightning detection system. If lightning is detected, there are two audible warning signs:
1 long blast = Lightning imminent, immediately take cover
3 short blasts = Reduced danger
A strobe light will begin flashing and remaining flashing until safe conditions return.
The lightning detection system is activated during limited periods and therefore, the absence of warnings from the system should never be considered an indication that danger from lightning is not present.
