The CFA takes the safety of the participants of highest importance when dealing with inclement weather and/or heat. As such, we follow the VHSL (Virginia High School League) and NFHS weather guidelines. 

Lightning Safety Guidelines, as stated by VHSL & NFHS criteria for suspension and resumption of play
a. Evacuation plan in the event of thunderstorm, must leave the fields and take shelter.
b. When thunder is heard or a cloud-to-ground lightning bolt is seen, the leading edge of the thunderstorm is close enough to strike your location with lightning. Suspend play for thirty (30) minutes and take shelter immediately.
c. 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.
d. Any subsequent thunder or lightning after the beginning of the 30-minute count will reset the clock and another 30-minutes count should begin

Humiture (feels like temp) is 105 degrees and up, VHSL recommends no outside activities; 104 to 95 degrees, VHSL recommends no equipment (helmet, pads, etc) be used during activity; 94 to 90 degrees, VHSL recommends equipment be removed as often as possible (during breaks, on sideline, etc).
