RECOMMENDED LIGHTNING PROCEDURES

In the United States, there are an estimated 25 million cloud-to-ground lightning flashes each year. Lightning can strike as far away as 10 miles from the rain area in a thunderstorm. That’s about the distance you can hear thunder. When a storm is 10 miles away, it may be difficult to tell a storm is coming. IF YOU CAN HEAR THUNDER, YOU ARE WITHIN STRIKING DISTANCE. SEEK SAFE SHELTER IMMEDIATELY! The first stroke of lightning is a deadly as the last. If the sky looks threatening, take shelter before hearing thunder.

FLASH TO BANG- a method used to assess how far away lightning is striking.

It is determined by counting the number of seconds it takes to hear a clap of thunder after witnessing a flash of lightning. The number of seconds is then divided by five to get the distance in miles, to the lightning flash. Generally a 30-second or less flash-to-bang count suggests removal of the athletes and any spectators from the field to a safe structure.

SAFE STRUCTURES – The most idea safe structure is fully enclosed.

A safe structure is a substantial building with plumbing, electrical wiring and telephone service, which all aid in grounding the structure. A fully enclosed automobile with a metal roof and rolled up windows is also a reasonable choice. However, it is IMPORTANT to avoid contact with any metal while inside the vehicle.

THIRTY-MINUTE RULE

Once lightning has been recognized, it is recommended to wait at least 30 minutes after the last flash of lightning is witnessed or thunder is heard. Given the average rates of thunderstorm travel, the storm should move 10-12 miles away from the area. This significantly reduces the risk of local lightning flashes. Any subsequent lightning or thunder after the beginning of the 30-minute count should reset the clock and another count should begin.

ALL adults (referees, coaches, administrators, parents) are responsible for the safety of the players. No death of a child is worth getting a game or practice in. ALWAYS err on the conservative side when it comes to lightning storms.
