Mexico City faces heavy rain and flooding risks today as authorities issue Yellow Alert warnings, while temperatures fluctuate between 18°C and 32°C nationwide. The National Meteorological Service (SMN) has confirmed the alert for the capital and surrounding states, advising residents to prepare for potential disruptions. In Puebla, temperatures are expected to reach 28°C, according to official forecasts.
The Yellow Alert, the second-highest warning level in Mexico’s meteorological system, signals “significant risks” of flooding, landslides, and localized flooding in urban areas. Authorities have urged residents to avoid unnecessary travel and stay updated through official channels. Meanwhile, the SMN’s latest bulletin indicates that while rain is concentrated in the center of the country, other regions will experience heatwaves, with some areas exceeding 35°C.
This weather pattern follows weeks of erratic rainfall across Mexico, with the National Water Commission (CONAGUA) reporting elevated water levels in several reservoirs. The combination of heavy rain and urban drainage challenges has prompted local governments to reinforce flood defenses in high-risk zones.
Why Is a Yellow Alert Issued for Mexico City?
The Yellow Alert in Mexico City is triggered when meteorological conditions meet specific risk thresholds established by the SMN. According to the National Meteorological Service’s official criteria, this level indicates:
- Rainfall exceeding 50mm in 24 hours in urban areas
- Risk of localized flooding in drainage systems
- Potential for landslides in mountainous regions
- Wind speeds reaching 60-80 km/h in some areas
For Mexico City specifically, the alert comes as the city’s drainage system—already strained by rapid urbanization—faces additional pressure from the heavy rainfall. The Mexico City Environment Secretariat (SEDEMA) has activated emergency protocols, including the deployment of additional drainage maintenance crews and the monitoring of critical infrastructure.
What to Expect: Temperature and Rainfall Forecasts Across Mexico
While Mexico City braces for rain, other regions will experience contrasting weather patterns. The SMN’s latest forecast breaks down as follows:
| Region | Rainfall Risk | Temperature Range (°C) | Alert Level |
|---|---|---|---|
| Mexico City (CDMX) and State of Mexico | Heavy rain, localized flooding | 18°C – 26°C | Yellow |
| Puebla | Scattered showers | 20°C – 28°C | Green (Monitoring) |
| Northern States (Coahuila, Chihuahua, Sonora) | Dry, heatwave conditions | 30°C – 38°C (some areas >40°C) | Green |
| Southern States (Oaxaca, Chiapas, Veracruz) | Moderate to heavy rain | 22°C – 32°C | Yellow (some areas Orange) |
In Puebla, where temperatures are expected to peak at 28°C, the state government has advised residents to stay hydrated and avoid outdoor activities during peak sun hours. The Puebla State Civil Protection Agency has issued a statement urging caution in areas prone to landslides, particularly near the city’s outskirts.
How Are Authorities Responding to the Weather Alert?
Both federal and local governments are coordinating responses to mitigate potential risks. Key actions include:
- Emergency Drainage Maintenance: Mexico City’s government has deployed 500 additional workers to clear debris from storm drains, with a focus on the historic center and Roma-Condesa neighborhoods, which are particularly vulnerable to flooding. The SEDEMA reports that 12 high-risk zones have been identified for priority attention.
- Transport Disruptions: The Mexico City Metropolitan Transport Authority (STCM) has announced potential delays on the Metro and Metrobús systems, particularly in lines 1, 2, and 6, which serve flood-prone areas. Passengers are advised to check official updates before commuting.
- Health Warnings: The Ministry of Health has issued a reminder about the risks of leptospirosis and dengue fever in areas with standing water. Hospitals in CDMX and Puebla have been placed on high alert for an influx of patients with waterborne illnesses.
- Agricultural Impact: In states like Puebla, where agriculture is a key industry, farmers are monitoring the forecast closely. The Mexican Ministry of Agriculture reports that while some crops may benefit from the rain, excessive moisture could damage corn and bean harvests in the coming weeks.
What Happens Next: Updates and Safety Advice
The SMN will issue hourly updates on its official website and through its social media channels (@conagua_clima on X/Twitter and Facebook). Residents in alert zones are advised to:
- Monitor local news for real-time alerts from civil protection agencies
- Avoid crossing flooded streets or walking near drainage channels
- Keep emergency kits stocked with water, non-perishable food, and first-aid supplies
- Check on vulnerable neighbors, particularly the elderly and those with mobility challenges
The next critical update from the SMN is scheduled for 18:00 local time (00:00 UTC), when meteorologists will assess whether the Yellow Alert should be extended or downgraded. Meanwhile, the National Civil Protection Coordination (CNPC) will hold an emergency meeting at 14:00 local time to evaluate response efforts across high-risk states.
How This Weather Pattern Compares to Recent Trends
This week’s weather follows a pattern of increasingly erratic rainfall across Mexico, a trend that climate experts attribute to a combination of natural variability and long-term climate change impacts. According to the National Institute of Ecology and Climate Change (INECC), Mexico has seen a 15% increase in extreme precipitation events over the past decade, with urban areas like CDMX and Monterrey experiencing the most significant changes.
In 2023 alone, Mexico City declared three Yellow Alerts for flooding, with the most severe occurring in September when 120mm of rain fell in 24 hours, causing widespread disruptions. This year’s alerts come earlier in the rainy season, which typically peaks from June to October. The SMN attributes the shift to the persistence of a high-pressure system over the Gulf of Mexico, which is funneling moisture toward central Mexico.
Key Takeaways for Residents and Travelers
- Mexico City: Expect heavy rain with potential flooding between 10:00 and 20:00 local time. Carry an umbrella and avoid non-essential travel.
- Puebla: Temperatures will be warm (up to 28°C), but scattered showers may occur in the afternoon. Monitor local forecasts for sudden changes.
- Northern Mexico: Heatwave conditions persist—stay hydrated and limit outdoor activity between 12:00 and 18:00.
- Southern Mexico: Orange Alerts remain in effect for Oaxaca and Chiapas; landslide risks are elevated in mountainous areas.
The SMN emphasizes that while the Yellow Alert indicates significant risks, it is not an evacuation order. However, residents in flood-prone areas are encouraged to prepare for possible disruptions to power and water services.

As Mexico navigates this complex weather pattern, authorities are urging both residents and visitors to remain vigilant. The combination of heavy rain in the capital and extreme heat in the north underscores the importance of staying informed and prepared. For those planning travel, checking real-time updates from the Secretariat of Communications and Transport is advised, as road conditions may deteriorate rapidly in affected areas.
Next Update: The SMN will provide a detailed analysis of the weather system’s evolution at 18:00 local time (00:00 UTC) on June 16. Further advisories from civil protection agencies will follow as conditions develop.
