Fans excited to see the Zac Brown Band at the 2015 Voodoo Music + Arts Experience in New Orleans on Sunday (Nov. 1) were left disappointed when the festival canceled all of the day's sets due to "dangerous weather conditions."

The weather began to be an issue on Saturday (Oct. 31), but by Sunday, "forecasted persistent rain and flash flood warnings for Orleans Parish" forced the festival's organizers to call off the event's final day.

"Fan safety is the top priority for the producers of the festival," a note on the event's website reads, "and current conditions at City Park do not meet our standards for maintaining a safe experience."

Fortunately, the festival's organizers made an exception to their "no refunds" policy and provided refunds to disappointed fans. Information on refunds is available on the Voodoo Festival's website.

"Say safe, everyone!" the Zac Brown Band tweeted after news of the cancellation was announced.

In addition to the Zac Brown Band, Jason Isbell and Ryan Bingham, among others, were also on the bill for this year's Voodoo Festival. Isbell played on Friday (Oct. 30), while Bingham performed Saturday (Oct. 31).

The Zac Brown Band are scheduled to perform at the 2015 CMA Awards on Wednesday (Nov. 4). They are nominated for Vocal Group of the Year at the awards ceremony.
