In the last 24 hours, through the Popocatepetl volcano monitoring systems, 77 exhalations were identified, accompanied by steam and gas, that the wind dispersed to the east-southeast (image 1) . During the night was observed a continuous emission of steam and gas to the east (image 2) .
Additionally were recorded 166 minutes of tremor.
At the time of this report, it is partially observed a continuous emission of steam and volcanic gases to the east (image 3).
Last April 8, with the support of the Federal Police, experts from the National Disaster Prevention Center (CENAPRED) and the Institute of Geophysics from the National Autonomous University of Mexico (UNAM), performed a surveillance overflight of Popocatepetls crater.
During the overflight, it was not possible to corroborate or discard the presence of a new lava dome due to the intense cloudiness, in addition to a high emission of steam and gases in the crater area, however, the monitoring of the Popocatépetl volcano is carried out 24 hours. Any change in activity will be reported in a timely manner

CENAPRED emphasizes that people SHOULD NOT go near the volcano, especially near the crater, due to the hazard caused by ballistic fragments (image 7) and in case of heavy rains leave the bottoms of ravines by the danger of landslides and debris flows.
The Volcanic Traffic Light Yellow Phase 3.
In case of ashfall, address the following recommendations:
• Cover nose and mouth with a handkerchief or face mask.
• Clean eyes and throat with pure water.
• Avoid contact lenses to reduce eye irritation.
• Close windows or cover them up, and stay indoors as much as possible.
Popocatepetl Volcano monitoring is performed continuously 24 hours a day. Any change in activity will be reported in due course.
The scenarios foreseen for this phase are:
1. Rapid growth of domes of large dimensions and their destruction in strong explosions.
2. Persistence of fumaroles, gas and slight falls of ashes in nearby areas.
3. Explosions of increasing intensity with the release of incandescent fragments.
4. Possible medium-range pyroclastic flows.
Special emphasis is placed on the following recommendations:
1. Continue with the security radius of 12 km, so that staying in that area is not allowed.
2. Control the traffic between Santiago Xalitzintla and San Pedro Nexapa, via Paso de Cortés.
3. To the Civil Protection authorities, maintain their preventive procedures, in accordance with their operational plans.
4. The population is recommended to raise the attention to the notices of the authorities of their locality and is exhorted not to approach the volcano, much less to the crater.
The monitoring of the Popocatépetl volcano is carried out continuously 24 hours a day. Any change in activity will be reported in a timely manner. The level of the Volcanic Warning Semaphore will depend on the evolution of the activity of the volcano.
