The jackpot for Powerball jumped for a third time Wednesday, pushing the grand prize to $500 million before the drawing Wednesday night, said Carolyn Hapeman of the New York Lottery. As the numbers were drawn, the jackpot rose to $564.1 million.

The winning numbers are 11, 13, 25, 39, 54. The Powerball number is 19.

The jackpot "bump," as it's called, is related to higher-than-anticipated ticket sales. Typically, sales in big-prize multistate games increase when the jackpots reach $300 million or more.

Wednesday night's drawing was the 21st since the last Powerball jackpot of $90 million was won on Nov. 29 by a ticket holder in Washington state.

At $500 million, the lump-sum payment was worth $337.8 million, so the lump sum climbed higher last night, too.

"Sometimes, after all the sales from all the states are tallied up, the jackpot can end up being more than the advertised amount," Hapeman said. "A vast majority of the time this happens is when the jackpot is already a large amount, like it is now."

It has happened once in this run of climbing jackpots; Saturday's announced jackpot was for $380 million. After the numbers were drawn, the jackpot went to $394 million. The latest jackpot also marks the fifth largest in the history of big-prize U.S.-based lottery games.

The odds of winning a Powerball jackpot are 1 in 175,223,510.
