Amid the historic floods in Houston and surrounding areas of Texas, Houston Texans defensive end J.J. Watt started a fund for those affected by Hurricane Harvey.

On Sunday, Watt posted a video promoting his YouCaring page that originally had a goal of $200,000.

"That's our city," Watt said. "It's very tough to watch your city get hit by such a bad storm and not be there to help. Not be there to help with the recovery, help with the process. It's very tough."

Less than two hours later, Watt’s followers hit the $200,000 goal.

Watt later raised the goal to $500,000 on Sunday night.

"Houston's a great city," Watt said. "We're going to come out of this stronger than ever, but we're going to need a lot of money to help these people rebuild."
