Weather Safety: Who is responsible for being prepared?

Racing as we all know, 99% of the time is an outdoor sport.  We are out in the various elements nature can throw out at us.  However, thunderstorms, lightning, and other forms of severe weather are issues that have to be taken seriously.  We were reminded one week ago at Ponoco when their event was rained on and severe weather rolled through, and 9 fans were struck by lightning, killing one.  However, who is responsible in terms of being prepared?  Obviously, the track should be prepared.  They should be in contact with the local National Weather Service and law enforcement agencies in order to know what is going on.  Technology is also helpful, as promoters/organizers can have radar and updates in the palm of their hands with smartphone technology currently available. Plans should be in place how they will handle severe/inclement weather situations.  They should use the information gathered to make decisions that are in the best interest of fan/driver/employee safety.  This may not always be popular, but it will keep everyone safe.   However, the fans have to be aware as well.  That same technology promoters have, we do as well.  I was put in the position the night before Pocono at Federated Auto Parts Raceway at I-55, as severe weather and lightning rolled through.  I had also been in that position at Peoria during the UMP Summernationals, which were all aluminum bleachers.  Some people don't put much thought into it, but all it takes is ONE strike and it can be devastating.  You have to be willing to leave before being told to, although some are too stubborn to.  I try to hold out myself, but I am not willing to risk my life sitting out in a dangerous situation for too long.
The event at Pocono serves us all a sobering reminder that lightning can, at ANY TIME, strike and injure/kill ANYONE.   We ALL, fans and promoters/track officials alike, ALL have to be prepared to take appropriate actions whenever weather arises.  Remember, no race is more valuable than your personal health and safety.  Be aware, stay alive.
