According to Houston Press photographer/reporter Marco Torres, who was on site, Free Press Summer Fest was suspended and evacuated for nearly an hour after a severe thunderstorm struck shortly before 6:30 p.m. As per the previously announced protocol, festivalgoers were ushered into NRG Center, although Torres says many took the opportunity to call it a day and head to their cars.

About 7:25 p.m., FPSF tweeted that the evacuation had been lifted and the festival reopened.

Torres said he was waiting for Big Grams to perform when the evacuation announcement came over the PA system. The message also appeared on the FPSF mobile app, he added.
