Firefly music festival was shut down prematurely last night because of inclement weather.

At 9:51 p.m., about 10-minutes after the festival's Saturday headliner Kings of Leon were supposed to go on, the Firefly Twitter account @LiveatFirefly tweeted for festival goers to clear the grounds, The Woodlands, and seek shelter.

Shortly thereafter, an announcer called over a loudspeaker for everyone to clear the festival grounds in anticipation for severe weather, despite the fact that it had yet to begin raining in the area.

The timing of the evacuation announcement interrupted performer Kid Cudi who took the Backyard Stage at 9:30 p.m. A tornado warning for the area was broadcast on giant screens surrounding the stage.

As concertgoers exited, lightning strikes began and high winds threatened camping tents canopies. Campers were sent a cell phone alert to take down their camping equipment around 11 p.m. and sent out a tweet with the same mandatory request.

Firefly had already anticipated the bad weather, and sent out a revised Saturday schedule, moving some acts to earlier spots in an attempt to dodge Mother Nature.  However, headliners Kings of Leon and Steve Aoki were unable to perform at all.

At 12:32, festival organizers tweeted that the shows would not resume due to continued storms but that Sunday shows would proceed as planned.

Shortly thereafter, Firefly organizers tweeted the festival was attempting to reschedule artists who were unable to perform because of Saturday night's severe weather.
