Latin America & The Caribbean Weekly Situation Update as of 30 June 2025

KEY FIGURES

• 3.2M suspected cases of dengue in Latin America and the Caribbean so far in 2025
• 9.3K people displaced following attacks in Artibonite, Haiti
• 109K people affected by heavy rainfall and flooding in Chocó, Colombia

MEXICO: HURRICANE SEASON

Tropical Storm Flossie formed in the eastern Pacific on 30 June and is forecast to strengthen into a Category 2 hurricane by 2 July as it tracks northwest along Mexico’s southwestern coast. Authorities issued tropical storm warnings for Guerrero, Michoacán, Colima, and Jalisco, with forecasts warning of life-threatening flooding and mudslides in highland areas. The storm follows the 30 June landfall of Tropical Storm Barry near Tampico in northern Veracruz. Though it quickly dissipated over eastern Mexico, Barry brought up to 200 mm of rain and triggered flood concerns in San Luis Potosí and Tamaulipas. This comes just one week after Hurricane Erick’s landfall. The early timing and high frequency of named storms on both coasts point to an active and potentially dangerous hurricane season across Mexico and the region.

COLOMBIA: FLOODING

Increased rainfall throughout the month of June has triggered severe floods and strong winds in Chocó, a department on Colombia’s Pacific coast. On 19 June, the Governor of the department declared a state of public calamity after heavy rainfall, severe flooding and gale-force winds affected more than 109,600 people across 23 municipalities - some 76 per cent of the department. The severe weather has caused widespread destruction, particularly in coastal areas, and resulted in significant losses to crops and livestock. Flooding has also affected key public infrastructure and essential services, including health, education and livelihoods.

HAITI: VIOLENCE & DISPLACEMENT

On 22 June, an armed group attacked La Chapelle in Haiti’s Artibonite department, forcing over 9,300 people (2,386 households) to flee. The attackers burned the police station, the District School Office, homes, and businesses, and set up roadblocks to block police access. Most displaced people remain within Artibonite—about half stayed in La Chapelle, while others moved to Verrettes and Petite Rivière. Approximately 94 per cent stay with host families, and the rest shelter in seven displacement sites, six created after the attack. This incident highlights Haiti’s worsening crisis, where nearly 1.3 million people face internal displacement due to escalating violence—the highest number ever recorded. Humanitarian groups, including IOM, continue to monitor displacement and coordinate responses to urgent needs.

REGIONAL: DENGUE & YELLOW FEVER

As of epidemiological week 23, the Americas have reported over 3.2 million suspected dengue cases in 2025, including 1.29 million confirmed cases, 4,115 severe cases, and 1,450 deaths. Although cases have decreased by 70 per cent compared to the same period in 2024, transmission remains high in Brazil and is rising in parts of Mexico and Costa Rica. At the same time, yellow fever continues to spread in South America, with 235 confirmed cases and 96 deaths reported in 2025 across Bolivia, Brazil, Colombia, Ecuador and Peru. In Peru, 38 confirmed cases and 13 deaths have prompted an intensive vaccination campaign across five Amazon regions. Although no animal outbreaks have been officially reported in Peru, primate deaths in neighbouring countries - often an early warning sign - highlight ongoing risks of further human transmission.
