In Juchitán de Zaragoza, at least 100 homes, as well as schools, public buildings, and a library were inundated with water up to deep, exacerbating damage from the 2017 earthquake. Seawater flooded palapas and streets in Playa Vicente. The Río de los Perros rose to a level of and spilled its banks in multiple sections. A school was closed in the city as a result of the swollen river and flooding. Near the source of the river, in the Sierra Mix-Zapoteca neighborhood, water overtopped a bridge. River currents dragged garbage and tree branches downstream, forming a dam at the bridge; the river overflowed and flooded two streets. Police closed the bridge and the flooded streets. The river also overflowed in Juchitán's 8th section, with floodwaters submerging streets.
