A stop on Luke Bryan's 2015 Farm Tour has been postponed due to weather -- for the second time.

Bryan was originally scheduled to perform in Columbia, S.C., on Oct. 3, but due to uncooperative weather, the show was rescheduled for Sunday (Oct. 11). However, on Saturday (Oct. 10), Bryan revealed on Twitter that, once again due to weather, the concert had been postponed again. A new date has not yet been announced.

The Columbia area has now seen heavy rainfall two weekends in a row. Orangeburg County Emergency Services Director Bill Staley tells the Times and Democrat that no further major impact is expected from this weekend's rain, but that recovery efforts from the previous rainfall are "still getting there."

Bryan has had tough luck with this year's Farm Tour. After kicking the trek off in Ft. Wayne, Ind., on Sept. 30, the country superstar was forced to postpone the next three dates, in Lexington, Ky., Knoxville, Tenn., and Columbia. The Lexington concert was rescheduled from Oct. 1 to Oct. 6, while the Knoxville show, originally scheduled for Oct. 2, will occur on Monday (Oct. 12).

“I know you guys are mad. I am heartbroken. We schedule Farm Tour in October because it is historically the driest month of the year,” Bryan wrote on Twitter after postponing his Knoxville show. “ATVs were bogging up. I will play in the rain, but I can’t strand you guys in your vehicles for days.

“Been doing Farm Tours for seven years, and this is the first time we’ve encountered this. We will learn and constantly get better. So sorry,” he continues. “Farm Tour has forever been a growing dream of mine. This year is our biggest so far. Hang in there with me. I swear I will make it count.

“Seeing country fans pile into places where no one ever thought a show would ever be possible is the most gratifying ever,” Bryan concludes. “Love y’all.”

The singer tells Billboard, "This has certainly been our most challenging year, but it’s also been our biggest ... We’re going to make it up to the fans every way we can. The fun thing about [Farm Tour] is that there is no complacency because it throws you curve balls every year. It keeps everybody on their toes."
