The heaviest rainfall is expected between 3:00 PM today and 2:00 AM on Thursday, July 31st. Expect rainfall between 15 and 29 millimeters during this period. Winds will also pick up, gusting up to 50 kilometers per hour.
How to Prepare for the Downpour
The Secretary of Integral Risk Management and Civil Protection (SGIRPC) has issued several key recommendations:
- Clear those drains! Remove trash and debris from drains inside and outside your home. This helps prevent flooding.
- Seal it up! Close doors and windows tightly to prevent leaks.
- Don’t risk it! Avoid crossing streets with running water. The current can be much stronger than it appears.
- Gear up! If you must go out, use an umbrella and wear a waterproof jacket or raincoat.
Broader Weather Patterns: It’s Not Just CDMX
CDMX isn’t the only region experiencing severe weather. The Mexican monsoon and tropical waves are contributing to widespread rainfall across the country. According to the National Water Commission (Conagua), several other states are also at risk.
- Oaxaca and Chiapas: Expect very heavy rainfall (75-150mm).
- Sinaloa, Nayarit, Jalisco, Colima, Guerrero, Michoacán, Veracruz, Tabasco, Yucatán, Campeche, and Quintana Roo: Prepare for heavy to very heavy rainfall (50-75mm).

The Science Behind the Storms
The combination of the Mexican monsoon, tropical wave number 17, and low-pressure systems are creating unstable atmospheric conditions. This leads to increased moisture and the development of thunderstorms. Climate change is also playing a role in the intensity and frequency of these events.
