1. Schedule Format
Lightning Guidelines – Developed using guideline and position statements from the
NFHS,HATA,and NCAA – 08/17/09
A. Prior to contest site being used, safe locations* shall be identified for all players.
B. Prior to the contest beginning, staff (game manager, athletic trainer, official) shall confer about weather conditions and league guidelines.
C. If lightning or thunder is seen/heard, a flash-to-bang method** should be used to determine when to clear field.
D. The National Severe Storms Laboratory recommends that athletic participation cease when lightning is detected within 6 miles. For our purposes this will be indicated by a 30-second flash-to-bang count as assessed by an ATC/official/game manager.
E. Thirty-minute rule. Once play has been suspended, wait at least 30 minutes after the last thunder is heard or flash of lightning is witnessed prior to resuming play. Any subsequent thunder or lightning after the beginning of the 30 minute count reset the clock and another 30 minute count should begin.
F. Hold periodic reviews for appropriate personnel.
*Safe Shelter - The primary choice for a safe location from the lightning hazard is any substantial, frequently inhabited building. The electric and telephone wiring and plumbing pathways aid in grounding a building, which is why buildings are safer than remaining outdoors during thunderstorms. It is important not to be connected to these pathways while inside the structure during ongoing thunderstorms. The secondary choice for a safer location from the lightning hazard is a fully enclosed vehicle with a metal roof and the windows closed. Convertible cars and golf carts do not provide protection from lightning danger. It is important not to touch any part of the metal framework of the vehicle while inside it during ongoing thunderstorms. (NATA –Position Statement Lightning Safety 2000)
**Flash-to-Bang Method - To use the flash-to-bang method, begin counting when sighting a lightning flash. Counting is stopped when the associated bang (thunder) is heard. Divide this count by five to determine the distance to the lightning flash (in miles). For example, a flash-to-bang count to thirty seconds equates to a distance of six miles. Lightning has struck from as far away as 10 miles from the storm center. “If you hear it, if you see it, flee it” Postpone or suspend activity if a thunderstorm appears imminent before or during an activity or contest, (irrespective of whether lightning is see or thunder is heard) until the hazard has passed. Sign of imminent thunderstorm activity are darkening clouds, high winds, and thunder or lightning activity.
