Weather Guidelines

Games will be played unless a cancellation is announced on WJON AM 1240, KCLD FM 104.7, or posted on the website www.cmysa.org.

Referees and Coaches should adhere to the following guidelines:

  • If lightning is within 5 miles, the game(s) should be suspended and shelter sought. A lightning detector can identify the distance accurately but may not be available. A rough guideline is to measure the time between the lightning flash and hearing the corresponding thunder. If it is 30 seconds or less, seek shelter. It may not be possible to determine which lightning strike generated which roll of thunder. A simple rule: If you can hear it, clear it!
  • Shelter should be in larger, enclosed structures. Smaller, open structures, tents, trees, isolated areas, etc, should be avoided. Cars, with windows rolled up, or buses can provide good shelter. Avoid contact with metal or other conducting materials to the outside surfaces. Do not stay in open, unprotected areas.
  • Games should not be restarted for at least 30 minutes after the last roll of thunder is heard.
  • Tournaments should inform participating teams of notification and evacuation plans and shelters near the playing sites.
