Although millions of Americans will be slightly disappointed to hear the news, the residents of Zephyrhills, Fla., are eagerly awaiting word of who purchased the winning $590.5 million Powerball lottery ticket at a local Publix grocery store.

The winner has 180 days to claim the jackpot, the second largest in U.S. history for a lottery drawing. The jackpot must be claimed within 60 days of Saturday's drawing, however, for the winner to be eligible for the award's $370 million lump sum pay-out.

"I heard some 26-year-old girl won," Zephyrhills resident Gary Cooper told ABC News. The store where the winning ticket was purchased says it doesn't know the person's identity, but several residents of the Tampa-area suburb told reporters that they hope it's someone they know.

About 80 percent of possible Powerball combinations were sold ahead of Saturday's drawing.

"We don't promote or endorse the lottery, we offer it as a convenience," Publix spokeswoman Maria Brous told The Associated Press. Publix will be given $85,000 for selling the winning ticket.

The dollar amount of the jackpot is surpassed only by the $640 million Mega Millions drawing in March 2012 – however, that award was split by ticket-holders in three states.

A Sunday press release from the Florida Lottery revealed the location of the store.

"This is Florida's sixth Powerball jackpot winner, adding to our record of the most Powerball winners of any state since the game was introduced in Florida in January 2009," said Florida Lottery Secretary Cynthia O'Connell in the release. "It is also a big win for public education. This series of Powerball jackpot rollovers generated more than $40 million for the Educational Enhancement Trust Fund."

A message flashed across the top of the official Powerball website only reads: "There was one winner sold by the Florida Lottery for the last drawing's $590,500,000 grand prize." The game's jackpot is back down to $40 million.

Whoever the winner is, there's bound to be intrigue and the airing of dirty laundry. The last big Powerball winner, Pedro Quezada of Passaic, N.J., was "subject to potential arrest" after winning $338 million in March, authorities said, for not paying child support to his ex-wife.

The odds of winning the jackpot were about one in 175 million, according to the Multi-State Lottery Association. Ticket-holders stand a much better chance of winning smaller prizes, as low as $4, from drawings.

Powerball tickets are sold for $2 each in 30 states, the U.S. Virgin Islands and Washington, D.C. Winners must be identified to the public in all states except Delaware, Kansas, Maryland, North Dakota and Ohio, according to the lottery association.
