"FPSF officials are continuing to coordinate with Houston Police Department, Houston Fire Department and the Mayor's Office of Special Events to monitor weather conditions and determine when the park is safe for festivalgoers to return," the festival said in a statement.
According to KPRC, the storm cell is expected to pass in about 30 minutes. FPSF organizers were quick to stress on Twitter that the festival is not being canceled.
A little more than a half-hour later, the Houston Police Department announced that FPSF had reopened.
