Stay inside for 30 minutes after the last rumble of thunder. For all regular season house-league games, any games stopped (after the official game time) under the OBA Thunder Policy, would be considered over; and, for other times, the OBA Thunder Policy is to be applied. Direct strikes are responsible for only 50% of lightning-related deaths and injuries. Two other types of hazardous phenomena are caused by lightning. Ground current and side flash account for 60-80% of lightning-related injuries and deaths. A ground current is set up when lightning hits the ground, spreads out and sends a current through a victim. Side splash occurs when lightning hits a tall object, travels partly down the object and then jumps to a nearby victim.
