In Chiapas, environmental authorities have issued an alert due to dire air quality in the metropolitan area, specifically in the municipalities of Tuxtla Gutiérrez, Suchiapa, Berriozábal, and Chiapa de Corzo. The Secretaría del medio ambiente has labeled the air quality as 'Very Bad' due to the high levels of PM2.5 particles, which pose significant health risks to the population. This situation has forced the suspension of outdoor activities in parks and recreational centers to protect public health.

The poor air quality is primarily attributed to ongoing wildfires in the region, notably an active fire in the Sumidero Canyon and another near Plan de Ayala. These fires are exacerbated by specific wind patterns that are concentrating pollutants in the metropolitan area. Eva Margarita Paniagua, director of climate change at SEMANH, highlighted that the concentration of PM2.5 particles is a direct consequence of the smoke from these wildfires, which significantly diminishes the air quality and poses risks to residents' health.

Authorities are particularly worried about the impact of these forest fires, as they lead to increased pollution levels and associated health issues. Steps have been taken to mitigate outdoor exposure to these harmful air conditions, and further monitoring and intervention will be necessary to address the environmental and health concerns related to air quality in the region. Even as firefighting efforts continue, the community is urged to remain vigilant regarding outdoor activities until the air quality improves.
