Heavy rainfall and coastal flooding in Sinaloa

Overview

Heavy rainfall across Sinaloa has caused localized flooding and significant increases in water reserves. In Guasave, intense storms led to accumulations of up to 115 mm in areas such as Palos Blancos, prompting the municipality to enter a state of permanent alert as drainage systems became saturated. Following these events, precipitation in northern Sinaloa, including 136 mm in Villa de Ahome, has contributed to a recovery in the state’s dam system. As of mid-September, Conagua reported that Sinaloa’s dams had reached 46.8 percent of their conservation capacity. By September 23, 2026, water availability for the agricultural sector continued to improve, with reservoir levels reaching 49.8 percent. Despite this improved water outlook, the agricultural sector faces economic hurdles regarding capital and fertilizer access. While Proman has announced a planned $1.8 billion investment in a fertilizer plant in Topolobampo, immediate resource shortages and market uncertainty have caused farmers in the Valle del Fuerte to delay planting corn and beans. As of late September, the impact of Hurricane Polo shifted focus to coastal flooding. In Guasave, Civil Protection increased surveillance in fishing fields such as El Caracol, Boca del Río, and La Pitahaya, where rising tides reached some homes. By September 28, seawater entered residential sectors in Yavaros and seafood warehouses in El Etcho. By October 4, 2026, coastal areas in Guasave, including Las Glorias and Boca del Río, continued to face significant storm surges. Although surge intensity decreased following the influence of Hurricane Polo, high waves caused erosion that consumed portions of the beach. Aurelio Roy Navarrete Cuevas, director of the Sinaloa State Civil Protection Institute, stated that reported damage was primarily limited to the fishing fields of El Caracol and El Huitussi. By October 9, 2026, the continued seasonal rainfall has begun to provide relief for the livestock and mango sectors.
