Governments across Latin America are stepping up emergency preparations as forecasts point to the development of a powerful El Niño weather pattern that could bring months of drought, flooding, wildfires and extreme heat across the region. Officials are racing to strengthen disaster response systems, protect food and water supplies, and reduce the potential impact on millions of people whose livelihoods depend on agriculture, energy production and natural resources.
According to the Associated Press, countries throughout Latin America are implementing contingency plans well before the expected peak of El Niño, recognising that early preparation could significantly reduce the economic and humanitarian consequences. Authorities are expanding emergency response capabilities, reinforcing infrastructure and improving weather monitoring systems after previous El Niño events caused widespread destruction across the continent.
The climate phenomenon, which is caused by unusually warm ocean temperatures in the central and eastern Pacific Ocean, alters weather patterns around the world. According to Reuters, the U.S. Climate Prediction Center believes El Niño has a very high probability of strengthening throughout 2026, with forecasts suggesting there is an 81 percent chance it could become one of the strongest events recorded since modern observations began in 1950. Scientists expect the system to persist into early 2027.
The Associated Press reported that governments are preparing for a wide range of impacts because El Niño affects different countries in different ways. Some regions are expected to receive torrential rainfall that could trigger flooding and landslides, while others may experience prolonged drought, record temperatures and severe wildfire conditions. These contrasting weather extremes present significant challenges for emergency planners across Latin America.
Brazil has begun one of the region’s largest preparedness operations. According to the Associated Press, the country has deployed more than 4,600 personnel to strengthen wildfire prevention and emergency response efforts as officials anticipate increased fire risk in vulnerable regions, including parts of the Amazon. Authorities are also working to protect forests, rural communities and biodiversity from fires that could spread rapidly during prolonged dry conditions.
Reuters reported that El Niño is also expected to place considerable pressure on Latin America’s economies. Financial analysts at UBS warned that Colombia could be among the countries most exposed to the weather pattern because of its dependence on agriculture and hydropower. Reduced rainfall could affect electricity generation, while disruptions to farming and fisheries may contribute to higher food prices and increased inflation across several countries.
Peru is also taking extensive preventative action. According to Reuters, authorities have declared states of emergency across hundreds of districts considered at high risk from heavy rainfall and flooding linked to El Niño. The emergency measures allow the government to mobilise resources more quickly, improve flood defences and coordinate disaster response before the worst weather arrives. Reuters also reported that additional funding has been approved for infrastructure projects, flood mitigation and emergency preparedness as officials attempt to minimise damage to homes, transport networks and agriculture.
Elsewhere, the Associated Press reported that Ecuador is strengthening flood protection projects, while Costa Rica is increasing wildfire preparedness and improving emergency planning. Panama is preparing for the possibility of lower rainfall affecting operations at the Panama Canal, one of the world’s most important shipping routes, while Colombia is reviewing its energy resilience in case reduced river flows affect hydroelectric power generation. Peru has also expanded its climate monitoring systems to provide earlier warnings for communities vulnerable to flooding and landslides.
The economic consequences of a strong El Niño are expected to extend well beyond agriculture. Reuters reported that crop production, fisheries, transport infrastructure and electricity generation could all face disruption depending on how weather patterns develop over the coming months. Countries that rely heavily on hydroelectric power may need to increase the use of more expensive energy sources if reservoir levels fall because of prolonged drought.
Experts say the region’s previous experience with severe El Niño events has highlighted the importance of acting early. According to the Associated Press, although many governments have significantly improved forecasting, emergency planning and disaster coordination, preparedness remains uneven across Latin America. Climate specialists warn that delays in implementing protective measures could leave vulnerable communities exposed to avoidable losses if the event develops as forecast.
The World Meteorological Organization has also urged governments to strengthen infrastructure, safeguard essential services and support vulnerable populations before conditions worsen. Reuters reported that international climate experts believe the combination of a strong El Niño and long-term climate change could contribute to even higher global temperatures, increasing the likelihood of more intense heatwaves and weather extremes around the world.
Scientists stress that while El Niño is a naturally occurring climate phenomenon, rising global temperatures can intensify some of its impacts by increasing the likelihood of extreme heat, worsening drought conditions and contributing to more destructive wildfires. This combination is raising concern among governments that already face growing climate-related risks.
As Latin America prepares for the months ahead, officials continue to emphasise that prevention is far less costly than disaster recovery. As reported by the Associated Press and Reuters, countries across the region are investing in emergency planning, infrastructure improvements and early warning systems in the hope of reducing the human and economic costs of what forecasters believe could become one of the strongest El Niño events in decades.
