The US Embassy in Havana issued a security alert on February 3, 2026, warning of Cuba's increasingly unstable national electrical grid and fuel shortages affecting transportation nationwide, including long lines at gas stations, as posted by the US State Department's TravelGov account on X during the reporting window from 7:16 PM to 9:46 PM UTC on February 5, 2026. The alert details prolonged scheduled and unscheduled power outages across the country, including Havana, which impact water supply, lighting, refrigeration, and communications, according to the US Embassy statement. Businesses, hotels, and hospitals rely on generators but face disruptions due to fuel shortages. US citizens are advised to conserve fuel, water, food, and mobile phone charge and prepare for significant disruptions. The embassy also reported incidents of US citizens being denied entry upon arrival in Cuba and a spike in regime-sponsored protest activity directed at the United States, including anti-U.S. rhetoric. This alert follows the Cuban regime's suspension of all public transportation lines nationwide due to fuel shortages, announced at approximately 7:00 PM UTC on February 5, 2026, as previously reported. No resumption timelines for power or fuel supplies were provided in the US Embassy alert, which links to additional details at cu.usembassy.gov.
