Overview
- Mexico City, which received a six‑hour ash advisory Thursday after westward emissions from Popocatépetl, was later told no ash would fall following a change in wind direction.
- SGIRPC’s early notice covered all boroughs, but a senior official said the plume weakened and winds turned south, moving any ash away from the city.
- The National Weather Service kept the alert at Yellow Phase 2, a level that signals ongoing activity and calls for vigilance without evacuation orders.
- A CONAGUA–SMN Hysplit model projected possible dispersion toward Puebla, Morelos and Oaxaca, with potential reach to Veracruz depending on shifting winds.
- Protección Civil advised people to avoid outdoor activity, close windows, wear masks and eye protection, and clear any wet ash from roofs because the added weight can strain structures.
