Volcanic ash from Popocatépetl volcano observed at 6 100 m (20 000 feet) a.s.l., Mexico

Volcanic ash from Popocatépetl in Mexico was observed at 6 100 m (20 000 feet) above sea level at 03:36 UTC on April 6, 2026. The advisory was issued by the Washington VAAC at 03:54 UTC on the same date.

The VAAC report indicates continued volcanic ash emissions (VA EMS) were observed via GOES-19 satellite and numerical weather models. The primary ash clouds extended from the surface up to flight level FL200 (6 100 m, 20 000 feet). Remnant ash emissions at this altitude were observed in satellite images extending approximately 100 km (62 miles) south-southeast from the summit. Additional ash emissions at FL240 (7 300 m, 24 000 feet) were observed extending about 80 km (50 miles) east and east-southeast from the summit, with movement forecast to shift south-southeast. The current advisory does not state any Aviation Color Code.

Popocatépetl is a large, active stratovolcano located approximately 70 km (43 miles) southeast of Mexico City. One of Mexico’s most active volcanoes, its hazards include ashfall, lava flows, pyroclastic flows, and lahars. Major population centers at risk include Mexico City, Puebla, and nearby smaller towns within a 100 km (62 miles) radius.
