The WASA weather procedures are described in the weather policy PDF. This policy basically boils down to "when in doubt, show up to the field."

If anyone hears thunder or spots lightning, the referees should take immediate action. Do not continue to play!

• WASA Rec. matches for ages U12 and below… The match will be terminated. Everyone is advised to seek shelter.
• Middle School age and above… There will be a full 30-minute delay. Everyone is advised to seek shelter. Subsequent occurrences of thunder or lightning start a new 30-minute clock. If it is apparent that conditions will not improve, the match may be terminated.

Game cancellation information appears on the WASA home page in the announcement section as well as the WASA Facebook page.

If a specific game cancellation notice is not posted, the general rule is go to the game and let the referees at the field make the determination about whether a game is canceled or not.
