Guidelines for Game Officials and Game Management to Use Regarding Lightning The
purpose of this appendix is to provide information to those responsible for
making decisions about suspending and restarting games based on the presence of
lightning. 1.
National Severe Storms Laboratory (NSSL) staff strongly recommend that all
individuals should have left the game site and reached a safe structure or
location by the time the person monitoring the weather obtains a flash-to-bang
(lightning-to-thunder) count of 30 seconds (equivalent to lightning being six
miles away). This recommendation was developed as a practical way to make a
judgment in situations where other resources such as technology and
instrumentation are not available. In
addition, a smaller, but still real, risk exists with the presence of lightning
at greater distances. Unfortunately, current science cannot predict where within
the radius the next strike will occur. 2.
The existence of blue sky and the absence of rain are not protection from
lightning. Lightning can, and does, strike as far as 10 miles away from the rain
shaft. It does not have to be raining for lightning to strike. 3.
When considering resumption of a game, NSSL staff recommends that everyone
ideally should wait at least 30 minutes after the last flash of lightning or
sound of thunder before returning to the field of activity. 4.
If available, electronic detection devices should be used as additional tools to
determine the severity of the weather. However, such devices should not be used
as the sole source when considering terminating play. |
