Cyclonic Circulation and Tropical Wave No. 14 Bring Heavy Rain to Oaxaca
The combination of a mid- and upper-level cyclonic circulation and the movement of Tropical Wave No. 14 will create unstable weather conditions across much of Oaxaca this Wednesday. Heavy to very heavy rainfall is forecast, accompanied by lightning and strong wind gusts.
According to the 6:00 a.m. weather report issued by the State Coordination of Civil Protection and Risk Management (CEPCyGR), the most significant impacts are expected during the afternoon and evening, particularly in the Sierra Sur, Mixteca, and Papaloapan Basin regions.
Authorities warned that the rainfall could cause:
- Localized flooding
- Reduced visibility on highways
- Rising river and stream levels
- Localized impacts in vulnerable areas
High Temperatures Will Keep Conditions Hot and Humid
Despite the forecast for rain, hot weather will continue across much of the state.
Maximum temperatures are expected to range between 30°C and 37°C (86°F to 98.6°F), while high humidity will make conditions feel even hotter.
The Papaloapan Basin will experience the highest temperatures, reaching up to 37°C (98.6°F). The Isthmus of Tehuantepec and the Coast are expected to reach 35°C (95°F), while the Central Valleys will see highs of 32°C (89.6°F).
The coolest temperatures are forecast for the Sierra de Juárez, where lows could drop to 13°C (55.4°F).
Forecast Temperatures by Region
- Papaloapan Basin: 37°C / 22°C (98.6°F / 71.6°F)
- Isthmus of Tehuantepec: 35°C / 23°C (95°F / 73.4°F)
- Coast: 35°C / 22°C (95°F / 71.6°F)
- Sierra de Flores Magón: 34°C / 16°C (93.2°F / 60.8°F)

- Sierra de Juárez: 30°C / 13°C (86°F / 55.4°F)
Moderate Waves and Southerly Winds Along the Coast
The forecast also calls for southerly and southeasterly winds across much of the state, with wave heights of 1 to 2 meters (3.3 to 6.6 feet) along Oaxaca’s coastline.
These conditions may pose risks for maritime operations and recreational activities.
Tropical Storm “Douglas” Poses No Threat
CEPCyGR reported that Tropical Storm Douglas has formed over the Pacific Ocean. However, due to its distance from Mexico’s coastline, the storm does not pose a threat to Oaxaca and is not expected to significantly affect the state’s weather conditions.
Civil Protection Urges Residents to Take Precautions
In light of the storm forecast, Civil Protection urged residents to take preventive measures and avoid dangerous situations.
Key recommendations include:
- Do not attempt to cross flooded areas.
- Stay away from rivers and streams.
- Suspend outdoor activities during thunderstorms.
- Do not seek shelter beneath trees or utility poles.
- Drive carefully, especially in areas with reduced visibility or fog.
- Keep an emergency kit with important documents, a radio, and a flashlight.
- Follow updates only through official government communication channels.
Prevention Remains the Greatest Challenge
Although these weather conditions are common during the rainy season, specialists emphasize that risks increase when heavy rainfall coincides with inadequate infrastructure, overloaded drainage systems, and communities located in high-risk areas.
Authorities stressed that continuous monitoring and prompt attention to official weather advisories are essential to minimizing potential damage and protecting the public.
