Thunder and lightning necessitates that all contests be suspended. The occurrence of thunder and/or lightning is not subject to interpretation or discussion - thunder is thunder and lightning is lightning. If lightning and/or thunder is observed, all outdoor activities will be suspended immediately.
Players and spectators shall be directed to report to a shelter, a building normally occupied by the public or if a building is unavailable, participants should go inside a vehicle with a solid metal top (e.g. bus, van, car).
The officials and responsible authorities shall make every reasonable effort to resume and complete the contest, with full consideration of the weather and site conditions (as they affect safety and playing conditions).
The official/coaches shall wait 30 minutes from the time the last boom is heard and/or the last strike is seen before starting or resuming play.
If thunder/lightning is observed at the site of an outdoor contest by the officials/coaches 30 or fewer minutes prior to the scheduled start of that contest, the official/coaches and the responsible school authorities shall not permit the contest to begin. Before the contest can begin a 30-minute period void of any strike or boom must be observed.
If thunder/lightning is observed at the site of an outdoor contest by the officials during the playing of the contest, the official/coaches shall immediately cease play for 30 minutes. Play may not resume until there has been a period of at least 30 minutes in which a boom or strike has not been observed. The rules of the particular sport shall determine whether the contest is 'official' or must be resumed at a later date.
