The recent Pacific cyclone season It is marking a period of notable activity on the Mexican coast, with storms and tropical systems that have generated abundant rains, intense winds, and high waves in several states. While meteorological authorities maintain constant surveillance, the population of regions such as Guerrero, Oaxaca, Jalisco and Chiapas is already preparing to deal with the possible effects of these phenomena.
During the last weeks, the National Metereological Service (SMN) and the National Water Comission (Conagua) have reported the formation of several cyclonic systems off the Mexican Pacific coast, some of which have evolved rapidly and have required the activation of emergency protocols. Coordination with the National Hurricane Center The United States has been key to monitoring, in real time, the threat posed by these tropical cyclones.
Recent formation of tropical cyclones in the Mexican Pacific
Among the most recent phenomena is the development of potential tropical cyclone Four-E, located more than 600 kilometers south of Acapulco and near Zihuatanejo, Guerrero. According to the National Meteorological Service (SMN), this disturbance could become a tropical storm and cause significant rainfall, strong winds of up to 60 km/h and waves of up to 4,5 meters, mainly on the coasts of Oaxaca and GuerreroIn addition, surveillance has been extended along the coast, from Tecpan de Galeana (Guerrero) to Manzanillo (Colima), due to the potential impact of the system.
At the same time, the formation of the Tropical Storm Dalila, located near Zihuatanejo and Lázaro Cárdenas, with maximum winds of 65 km/h and gusts reaching 85 km/h. Dalila is the fourth system of the season, following Alvin, Cosme, and Hurricane Barbara, and has caused torrential rains in states such as Michoacán, Oaxaca, and Guerrero, while Jalisco and Colima have faced very heavy rainfall.
On the other hand, the evolution of Erick As a tropical storm centered south-southwest of Puerto Chiapas, it has reinforced the warning for a more active season than usual. Erick has brought intense rains, sustained winds, and the potential for flooding and landslides to vulnerable areas of Chiapas, Oaxaca, and southern Veracruz.
Pacific cyclone forecasts and warning zones
The official forecast predicts that during season 2025 Between 16 and 20 cyclone systems could form in the Pacific, which requires constant monitoring by authorities. Two active monitoring zones stand out: a low-pressure zone with a high probability of cyclone development south of Oaxaca and another south of Chiapas. These areas present favorable conditions for the development of new cyclones, so the National Meteorological Service (SMN) maintains alerts and updates information for coastal communities.
States like Jalisco The impact of these phenomena has also been felt, with heavy rains and possible flooding in the Guadalajara metropolitan area and other regions of the state. Furthermore, high waves of up to 3,5 meters and the interaction of humidity from the Pacific have generated cloudiness and showers in various areas. Maximum temperatures have exceeded 30°C, while significant drops have been recorded in mountainous areas.
Given this scenario, the National Coordination of Civil Protection reiterates the importance of maintaining surveillance over active and potential systems, reinforcing preventive measures in risk areas.
Recommendations for protection against cyclones and tropical storms
Authorities emphasize the need for the population follow official notices and take preventive measures to minimize risks from heavy rains, flooding, or landslides. Some of the most recommended actions include:
- Identify temporary shelters and previously established evacuation routes
- Have a emergency kit with documents, medicines, flashlights, radio and basic supplies
- Disconnect electrical devices and turn off gas and water valves when evacuating.
- Stay away from windows and dangerous objects during the cyclone.
- Do not spread rumors and consult only official government sources and platforms
For those living in low-lying areas or near rivers and streams, the risk of flash flooding is heightened, so it is recommended to remain alert to any changes in water levels and be ready to evacuate if directed by authorities.
Once the cyclone has passed, it is essential to take extreme precautions regarding possible damage to infrastructure, downed cables, or wet soil. Only when authorities confirm it is safe to do so should people return home.
