The United States Department of Homeland Security (DHS) announced on Wednesday that all immigrant detainees have been transferred out of the South Florida Detention Center — widely known as "Alligator Alcatraz" — citing concerns about the Atlantic hurricane season. The department's spokesperson, Lauren Bis, confirmed the transfers in a statement but did not specify how many people were moved or where they were sent, nor whether the closure would be permanent or temporary.
The facility, built on an abandoned airstrip inside Florida's Big Cypress Natural Preserve — a vast wetland area in the southern tip of the state — opened on July 3, 2025, after being constructed in a matter of days by Florida Governor Ron DeSantis's administration. Designed to hold up to 3,000 people, it was nicknamed "Alligator Alcatraz" in reference to the famous maximum-security Alcatraz Island prison in San Francisco, with officials openly noting that the surrounding swampland — home to alligators and pythons — served as a natural deterrent to escape. President Donald Trump, who has made mass deportation of immigrants a central policy of his second term, personally toured the facility alongside DeSantis shortly before it opened. Officials claimed the aluminium-frame tent structures were capable of withstanding Category 2 hurricane-force winds. The announcement of the transfers came the same day the National Hurricane Center reported the first named tropical storm of the 2026 Atlantic season.
The facility attracted controversy almost from the moment it was announced. Indigenous leaders from the Miccosukee and Seminole nations — communities with deep historical ties to the Everglades — opposed its construction as harmful to their homes and ceremonial sites. Detainees and their lawyers described conditions including denial of access to legal counsel, medical neglect, worms in food, non-functioning toilets, flooding floors with fecal waste, and pervasive insects. The American Civil Liberties Union (ACLU) filed a lawsuit alleging that the remote location was a deliberate strategy to cut detainees off from legal resources. DeSantis said in May the facility had always been intended as temporary and had processed and deported 22,000 people since opening.
Immigration advocates are sceptical of the official explanation for the transfers. "That's a nonsense excuse because they opened in the middle of the worst part of hurricane season last year," said Arianne Betancourt of The Workers Circle, a non-governmental advocacy group. Immigration attorneys reported that transfers had been quietly accelerating over recent weeks, with clients moved to facilities in South Florida, California, Arizona, Louisiana, and Texas — often without formal notice to lawyers or families. Attorney Katie Blankenship said all 50 of her clients had been moved and were temporarily unreachable. "They have been moved and disappeared into the system and are unavailable to family or counsel, typically for a period of about a week," she said.
Why this matters: The closure — even if temporary — marks a significant moment in a facility that became a flashpoint in the broader debate over U.S. immigration detention policy. Rights groups warn, however, that the underlying issues are far from resolved. "Transferring people out of this cruel facility is an important step, but it does not erase the harm that has already been done," said ACLU attorney Amy Godshall, who called on authorities to permanently close the site. Advocates caution that transferring detainees to other facilities disperses rather than resolves the hardship faced by immigrant families, while contractors involved in running the facility are widely expected to have profited substantially from its year of operation.
