ZEPHYRHILLS, Fla. – So far the winner hasn't come forward to claim the highest Powerball jackpot in history.

The lucky ticket was bought at a Publix supermarket in Zephyrhills, Fla., a city of about 13,000 people about 30 miles northeast of downtown Tampa.

The winner will have up to two months to claim the estimated $590.5 million jackpot.

Under Florida law, lottery winners in the state cannot remain anonymous; their names and city of residence must be made publicly available to anyone who asks, according to the state's lottery website. No one had come forward as of Monday morning.

Lottery spokesman David Bishop says that winners of big jackpots usually don't rush to claim their prize. They typically contact an attorney or accountant to get their affairs in order.
