The Metropolitan Area of the Valley of Mexico remains under a Phase I environmental atmospheric contingency due to high ozone levels. The Comisión Ambiental de la Megalópolis (CAMe) has confirmed that vehicle restrictions and health recommendations will stay in effect for Sunday, April 26.
Meteorological Factors Driving Pollution
Environmental authorities report that weather conditions on Saturday were unfavorable for the dispersal of pollutants. This was caused by an anticyclonic system that resulted in limited ventilation, weak winds, and high solar radiation.
These specific factors have favored the accumulation of ozone across the region. Air quality in various points of the Valley of Mexico is projected to remain between “bad” and “exceptionally bad” throughout Sunday.
Vehicle Restrictions for Sunday, April 26
To combat the pollutant levels, extraordinary measures are in place. The following vehicles must suspend circulation from 5:00 to 22:00 hours:
- Vehicles with hologram 2
- Vehicles with hologram 1 and license plates ending in 2, 4, 6, 8, and 0
- Vehicles with holograms 0 and 00, yellow stickers, and license plates ending in 5 or 6
- Vehicles without a hologram, those with temporary permits, demonstration plates, or foreign plates
- 50% of LP gas delivery units without a dry valve (even license plates)
local and federal cargo vehicles are restricted from 6:00 to 10:00 hours, even as applicable taxis will face limited circulation from 10:00 to 22:00 hours.
Exemptions and Permitted Vehicles
Certain vehicles are exempt from these restrictions and may continue to circulate. These include electric and hybrid vehicles, motorcycles, and those with an exempt hologram.
Exemptions also apply to emergency, health, and security vehicles, as well as authorized personnel and school transport. Vehicles for people with disabilities and those transporting refrigerated perishable products are permitted.
Public Health Recommendations
Authorities strongly advise the population to avoid outdoor exposure between 13:00 and 19:00 hours. This is especially critical for children, older adults, pregnant women, and individuals with cardiovascular or respiratory illnesses.
To reduce health risks, the CAMe recommends avoiding outdoor exercise and postponing cultural or sporting events held in open spaces. Residents are also encouraged to reduce travel, opt for remote perform, and avoid smoking in enclosed areas.
those needing fuel are advised to load gasoline either before 10:00 or after 18:00 hours.
Next Steps and Updates
The situation remains under close monitoring by environmental officials. A new update regarding the status of the environmental contingency is scheduled to be issued this Sunday, April 26, at 10:00 hours.
This upcoming report will be based on the evolution of air quality across the region and may determine if restrictions are modified or extended.
