In the last weeks of June 2025, several regions of Latin America have experienced a notable intensification of rainfall and adverse weather events. due to the passage of multiple tropical waves. This phenomenon, common during hurricane season, is causing concern among both meteorological authorities and the public, especially in countries such as Colombia, Venezuela, Mexico, Costa Rica, and El Salvador.
Tropical waves are elongated atmospheric disturbances that alter the behavior of winds and pressure in the tropics, causing abundant cloudiness, heavy rains and thunderstorms.These conditions result in periods of prolonged rainfall, often accompanied by strong winds and the risk of hazardous events such as flooding and landslides.
Colombia: Persistent rains and alert for new phenomena
Colombian authorities, through the Institute of Hydrology, Meteorology and Environmental Studies (Ideam), have warned about the Significant increase in rainfall in several regions, especially in the Caribbean and the Andean regionThe arrival of various tropical waves has caused heavy rainfall in departments such as La Guajira, Atlántico, Magdalena, Bolívar, Córdoba, Sucre, Cesar, Antioquia, and Chocó. Furthermore, the archipelagos of San Andrés, Providencia, and Santa Catalina are identified as particularly vulnerable areas.
The National Unit for Disaster Risk Management recalled that these phenomena can lead to Floods, strong winds, river floods and landslides, which requires citizens to pay attention to official announcements and adopt preventive measures. IDEAM emphasizes that the tropical cyclone season extends until November, so Monitoring and prevention remain a priority.
Mexico: interaction of tropical waves and cyclones
The interaction between a tropical wave and Cyclone Erick has generated abundant rains and intense wind gusts in states such as Oaxaca, Chiapas and Guerrero.The phenomenon has been reinforced by the presence of low pressure and other atmospheric conditions that favor the formation of storms, lightning, and high waves in coastal areas.
They anticipate heavy rainfall in other areas of the country, including Tabasco, Campeche, Yucatán, Quintana Roo, Michoacán, Puebla, Veracruz, and the State of Mexico. The rains may be accompanied by hail, as well as sudden rises in rivers and streams, increasing the danger for those living in areas prone to flooding and landslides.
Venezuela: Vigilance for the advance of tropical waves
The National Institute of Meteorology and Hydrology (Inameh) has been closely monitoring the movement of several tropical waves through Venezuelan territoryRainfall of varying intensity has been recorded in states such as Guayana Esequiba, Delta Amacuro, Monagas, Bolívar, Amazonas, Apure, Cojedes, Portuguesa, Falcón, Lara, Táchira, Mérida, Trujillo, and Zulia.
For the next few days, Inameh forecasts new tropical waves will enter the country, which will maintain the probability of precipitation, sometimes accompanied by lightning. The meteorological agency insists the importance of heeding official warnings and taking precautions, especially in mountainous areas and areas prone to flooding..
Costa Rica: Soil saturation and flood risk
The National Meteorological Institute (IMN) has indicated that The passage of tropical wave number 6 has generated intense rains in various regions, especially in the Northern Zone, North Pacific, Central and South Pacific, as well as the Central Valley and parts of the Caribbean. The soil in areas such as the Nicoya Peninsula, the mountains of the Northern Zone and the Sarapiquí Basin is highly saturated, increasing the danger of flooding and landslides.
In addition, it is expected that A new tropical wave (number 7) will enter the country over the weekend., reinforcing the possibility of widespread downpours with thunderstorms. The Mexican National Meteorological Agency maintains differentiated alerts by region and emphasizes the need to follow all official recommendations, especially in areas under orange and yellow alerts.
El Salvador and Central America: persistent rains and prevention
The Ministry of Environment of El Salvador has communicated that the The influence of tropical waves and the Intertropical Convergence Zone continues to cause rainfall throughout the country., with greater emphasis on the coastal slopes and areas vulnerable to flooding. Civil Protection maintains the yellow alert and recommends that the population remain vigilant against possible landslides, river flooding, and infrastructure collapse.
Recommendations for the impact of tropical waves
Meteorological authorities in the affected countries are insisting on a series of measures to mitigate the risks:
- Stay informed through official channels on the progress of tropical waves and weather conditions.
- Avoid areas prone to flooding and landslides; take shelter in safe places in case of a thunderstorm.
- Do not expose yourself to high waves already strong winds in coastal areas.
- Collaborate with local authorities and follow their instructions, especially in the case of preventive evacuations.
The current rainy season and the impact of tropical waves are testing the response and prevention capacity of Latin American countries. The rains will continue to affect different regions, with special attention to coastal, mountainous areas and those with saturated soilsCitizen vigilance and cooperation are crucial to minimizing damage and protecting lives.
