In Guatemala, the Fuego has low to moderate ash emissions, at the rate of 11-17 episodes per hour, accompanied by plumes between 4,500 and 4,800 meters asl. moving west and southwest.

Night glow is observed at 200-300 m. above the crater; this activity generates weak to moderate avalanches around the crater, and some stronger towards the drainage.

Ash falls are reported on Morelia, Santa Sofia, Sangre de cristo, San Pedre Yepocapa, and Panimache.
