CDMX Flood Map: Know the Most Vulnerable Neighborhoods and How to Prepare
Published: 26/06/2026 | 🕑 13:38
The rainy season in Mexico City presents a continuous challenge for urban infrastructure and its residents. It is crucial for citizens to identify critical areas that have historically recorded high levels of water accumulation. The capital’s Risk Atlas serves as an essential tool to locate neighborhoods and roads most susceptible to severe flooding, enabling residents to take preventive measures against intense meteorological phenomena.
Which Boroughs Experience the Most Flooding in CDMX?
The areas with the highest incidence of these events are primarily concentrated in low-lying zones or those with drainage network deficiencies. Among the boroughs with the highest records of affectations are:
- Gustavo A. Madero: La Laguna Ticomán and Lindavista.
- Azcapotzalco: Parque Tezozómoc and the ex-refinery 18 de marzo area.
- Miguel Hidalgo: Hipódromo de las Américas and Reforma Social neighborhood.
- Cuajimalpa: Zedec Santa Fe neighborhood.
- Tláhuac: La Ciénega and the surroundings of the Metro Chapultepec station.
These areas frequently experience rainfall volumes that exceed the capacity of the drainage pipes.
What to Do in Case of a Flood?
During a flood, the absolute priority is to safeguard physical integrity. If you are on the street, avoid walking or driving through water currents, as their force and depth can be deceptive. Seek refuge in high areas, stay away from electrical installations, light poles, or uncovered manholes, and always follow the instructions of Civil Protection personnel.
If you are inside a building, disconnect the electrical supply and close gas valves to prevent accidents. Avoid touching any electrical appliance if the floor is wet or if water has entered the property. Stay informed through official sources, and if authorities indicate an evacuation, leave immediately following the established routes to safe meeting points.
Why Do These Neighborhoods Flood?
Factors such as the accumulation of solid waste in storm drains, increasing urbanization that impermeabilizes the soil, and a lack of maintenance in the hydraulic system are the primary causes behind these recurrent floods.
How to Consult the CDMX Risk Atlas (Most Flooded Roads)
The Mexico City Risk Atlas offers a detailed platform displaying areas with high and medium risk levels. This resource allows users to verify if their home or daily commute routes are near critical points or roadways with a history of flooding. Knowing this information is vital for planning alternate routes during storms.
Recommendations to Protect Your Car During a Flood
Vehicle safety is also a priority during rainfall. It is recommended to avoid driving through underpasses or streets with water currents that exceed half the height of the wheels. If the vehicle stalls during a flood, do not attempt to restart it, as this can severely damage the engine.
Similarly, in any emergency, prioritize your physical well-being, stay away from electrical installations, and be attentive to warnings issued by Civil Protection authorities. Preparation and the use of available geographical data are the best defenses to minimize material and personal risks during the rainiest months of the year in the metropolis.
