Amazon has apparently zeroed in on its second North American headquarters — and it’s not Boston.

The Washington Post reported yesterday that Crystal City, Va., is in “advanced discussions” with Amazon, citing anonymous public and private sector officials.

The talks were described as more in-depth than the company has had with other cities that made the tech giant’s HQ2 short list. However, the Post cautions that it does not mean the deal is certain and that other cities might have “similar discussions.”

The Northern Virginia neighborhood is just across the Potomac River from the nation’s capital and discussions are apparently far enough along that one of the city’s prominent real estate developers, JBG Smith, has pulled some of its property off the market.

Sources also tell the newspaper that the announcement could come this month, following the midterm elections next week.

Shortly after the Post published its story, Mike Grella, Amazon's economic development director, addressed the “genius leaking info” about the plans in a tweet. “You're not doing Crystal City, VA any favors. And stop treating the NDA you signed like a used napkin,” he said, in reference to the non-disclosure agreement that all finalists had to sign.

Jeff Bezos, Amazon’s founder and president — and owner of The Washington Post — has said the company will make its final decision by the end of this year. The Seattle-based company received 238 proposals and narrowed its pool of finalists to 20 locations in January, including Boston.

Amazon plans to make $5 billion in capital investments in the city it chooses and hire 50,000 employees over the next 18 years. City and state lawmakers nationwide created economic incentives in a bid to attract Amazon’s second headquarters, that would bring in 50,000 jobs and $5 billion in investment.

The Walsh administration last year submitted the Suffolk Downs site in East Boston as the “perfect match” for Amazon’s second headquarters. HYM Investment Group’s founder Thomas O’ Brien told the Herald last month that plans to redevelop the site will proceed, regardless of Amazon’s decision.

A spokesperson for Amazon declined to comment. John Barros, the city’s chief of economic development, as well as Mayor Martin J. Walsh’s office, did not immediately respond to calls for comment. Boston City Councilor Lydia Edwards, who represents East Boston, yesterday she wasn’t sure whether or not Amazon has been in communications with the city.
