Whats the rule regarding stopping of play due to thunder and lightning?
If an umpire sees any lightning (bolt or flash) at any distance, play must be immediately stopped and all players must leave the field. Play may only resume after fifteen consecutive minutes free from lightning. The umpire will keep the official time. If you stop play, give it a good 30 minutes at least before you suspend a game, as even nasty thunderstorms often stop and allow games to resume. Be patient. Again, do everything possible to play a game, as we cannot always guarantee that postponed games will be made up.
