Nationwide power failure hits Caribbean island as American citizens warned to prepare

A nationwide power failure in Cuba has caused major disruptions for American travelers, with the U.S. Embassy in Havana advising citizens to prepare for ongoing grid instability. The crisis, including six outages in 2026, has led to extreme heat and reliance on outdoor cooling methods. Cuban officials have cited U.S. sanctions as a factor in the energy crisis, though the cause of the latest blackout remains unclear.
