Lightning is a severe hazard that must be viewed seriously.
Everyone should immediately seek shelter any time they believe lightning threatens them, even if a signal has not been sounded.
You will be warned by our thor guard lightning prediction system, which sounds one 15 second blast of horn signaling suspension of all activities (a strobe light will begin flashing and remain flashing until safe conditions return). You should immediately seek an appropriate, safe shelter.
You may resume activities only after three 5 second blasts of the horn are sounded and the strobe light stops flashing.
IF YOU REMAIN OUTDOORS AFTER THE WARNING IS ISSUED, YOU DO SO AT YOUR OWN RISK!!
