A spokesman for the Mercedes-Benz Superdome says they'll be watching the weather closely as rain is in the forecast Sunday for the Saints-Cardinals game, which kicks off at noon at the Dome.
Eric Eagan says the pre-game festivities at Champions Square could be affected, depending on how severe the weather is.
"Rain itself is not going to cancel our entertainment in Champions Square. The square will remain open provided the conditions are not deemed to be dangerous," Eagan said.
"And if there are dangerous conditions, strong storms, lightning, etc., we would certainly evaluate it and make the call to close the square and evacuate if that were required," he said.
Champions Square is scheduled to open at 9am. The gates of the Superdome will open at 10am.
