Lightning warning systems have been installed in Montvale at these locations:

When the lightning system is activated a horn will sound and the amber light will turn on. When this occurs the fields are closed and everyone must leave the field immediately. When the storm passes and there is no longer a threat of lightning, the horn will sound again, and the amber light will shut off.

YOU MUST LEAVE THE FIELD WHEN THE SYSTEM IS ACTIVATED. THERE ARE NO EXCEPTIONS.
