Producer Danny Wimmer was forced to cancel the second day of the Houston Open Air festival at NRG Park in Houston on the advice of meteorologists.

"The last thing we want to do is cancel a show, but we will not risk people getting hurt," Wimmer told WENN on Monday (26Sep16). "It takes nearly an hour to safely evacuate a site - including consumers, staff, vendors, and artists - so they can get to safety before a major storm hits. So we have to make the evacuation decision more than an hour in advance, even if there is still a chance the storm might not hit.

"I read all the comments on our social media, and I understand the frustrations that some people felt, but our job is to protect everyone. I don't make the decision lightly, but I would make the same decision again. We were seeing signs of storm cells expected to be heavy until 7pm, followed by another storm from the Gulf. We drill for these situations. When the decision was made to evacuate, everyone executed perfectly.

"We've been through this kind of experience twice before - at Monster Energy Welcome To Rockville 2015 (when a tornado hit near the site) and Monster Energy Carolina Rebellion 2013 - and are always committed to keeping people safe."

Deftones, Chevelle, Slayer and more acts were billed to take the stage when the decision was made to cancel.
