The third and final day of Governors Ball was cut short due to severe weather.
The music festival announced Sunday afternoon that the festivities would officially be canceled because of a high chance of lightning in the area. Earlier Sunday, it said doors would just open late.
"The safety of fans, artists and crew always comes first," said a posting on the website.
The scheduled artists for Sunday included Kanye West, Death Cab for Cutie and Two Door Cinema Club.
The organizers said anyone who purchased a Sunday ticket will receive a full refund. Fans who purchased a three-day pass will receive a partial refund. The website says all refunds should be processed within 21 days.
