Widespread Rains Across Mexico Due to Atmospheric River and DANA
The month of February begins with significant rainfall across Mexico, triggered by complex atmospheric conditions. The Servicio Meteorológico Nacional (SMN) has warned of heavy downpours, thunderstorms, and the potential for hail across various regions.
On February 4, 2025, various states were put on alert. The SMN forecast included strong intervals of rain, especially across states like Tamaulipas, Veracruz, and Oaxaca, where rainfall could reach up to 50 mm. Wilbur Menchaca, the chief meteorologist at the SMN, commented on the situation: “This weather pattern is primarily due to the interaction of low-pressure systems and tropical moisture coming from both coasts.”
Conditions across northern Mexico also reflected the severity of the situation. The SMN predicted thunderstorms and localized hail primarily affecting the central and eastern states. Reports indicated scattered thunderstorms across populous areas, including Mexico City, which could cause disruptions and chaotic traffic conditions.
“Rainfall this week is unprecedented for this time of year,” added Menchaca. “We are advising residents to exercise caution, as the combination of rain and wind can lead to dangerous conditions, including flooding and landslides, especially in hilly terrain.”
The impact of the rains is not limited to just storms. The cooler evening temperatures combined with high humidity have made for complicated living conditions. Despite the forecasted low temperatures during the mornings and evenings, during the day, soaring temperatures nearing 40 °C are expected across states like Sonora, Sinaloa, and Jalisco.
The SMN made specific predictions highlighting the states set to see the most rainfall and warned residents of the dangers posed by severe weather. To summarize:
- Heavy rain (25 to 50 mm): States like Tamaulipas, San Luis Potosí, and Veracruz.
- Moderate rain (5 to 25 mm): Areas of Nuevo León, Estado de México, Ciudad de México, and more.
- Isolated showers (0.1 to 5 mm): States such as Baja California and Michoacán.
Flooding has already begun to occur as infrastructure struggles to cope with the sheer volume of rain. For example, reports from Veracruz indicated rising water levels forcing evacuations and local authorities advising citizens to stay indoors.
“We are closely monitoring river levels across affected regions,” stated Carlos Ruiz, director of local disaster management. “Our main concern is for the safety of residents. We recommend avoiding flooded streets and staying informed on potential evacuations.”
Weather warnings are especially important considering the risk of landslides. High-alert regions include mountainous areas where conditions are ripe for sudden mudslides. “We’ve witnessed how quickly conditions can change,” Ruiz continued. “A small amount of rain can increase flood risks exponentially if the ground is already saturated.” This prediction has led to heightened vigilance from local emergency services.
Despite the risks, much of Mexico is also experiencing warmer weather, with expected highs reaching between 30 to 40 °C across states such as Colima, Guerrero, and Michoacán, juxtaposed with morning chills dropping to near freezing. For the women from Chiapas planning their weekend family gatherings, they should prepare for both sunny and rainy conditions.
To provide residents with the best preparedness measures, the SMN has issued guidelines emphasizing the importance of staying indoors during heavy rain, avoiding unnecessary travel, and keeping emergency supplies accessible. They advised against panicking, urging everyone to stay updated through their official channels.
Humidity is expected to remain high, complicate daily life with localized fog, and impair visibility along major highways. Soaring winds between 20 to 70 km/h, especially along the coastlines, pose additional risks, including flying debris from unsecured items.
On February 5, forecasters predict conditions will persist with several states—such as Chiapas, Guerrero, Morelos, and Oaxaca—continuing to collect rain. By maintaining these warnings, the SMN seeks to keep the public aware of sudden weather changes. A communal alert system has been put in place to facilitate timely updates as the situation evolves.
While the rains have created distress, they are also welcomed by many farmers who view them as necessary for crops severely affected during drought seasons. The SMN reported, “Indeed, many agricultural regions rely on precipitation during this period. It gives hope for recovering lost harvests.”
Animals are also impacted; reports suggest farmers are taking precautionary steps to shelter livestock adequately and reduce stress among the animals. Local markets could see fluctuations based on supply chain interruptions as truck routes are impeded.
No matter how beneficial the rain may be, the immediate dangers cannot be overlooked. The population is urged to stay safe and informed through the arduous days of rain and wind. With careful monitoring and preparation, residents can hope for brighter skies in the days following this challenging weather event.
