Hurricane Cosme caused flooding along the Pacific coast of Mexico in June 2013. The third named tropical cyclone of the 2013 Pacific hurricane season, the storm system formed from a tropical wave south of Manzanillo, Colima, on June 23. The cyclone intensified into a tropical storm on June 24, and soon after strengthened into a hurricane on June 25. Early the following day, Cosme attained its peak intensity as a Category 1 hurricane on the Saffir–Simpson scale with maximum sustained winds of 85 mph (140 km/h) and a minimum barometric pressure of 980 mbar (hPa; 28.94 inHg). However, Cosme then began to encounter stable air and lower sea surface temperatures, causing the system to weaken to a tropical storm late on June 26. The system continued to weaken and degenerated into a remnant low pressure surface trough about 690 mi (1,110 km) west-southwest of Cabo San Lucas, Mexico, on June 27. The remnants persisted until dissipating well east-southeast of the Hawaiian Islands on July 1.
In anticipation of the storm, the Servicio Meteorológico Nacional of Mexico issued a blue alert (minimum risk) for the states of Guerrero, Nayarit, and Baja California Sur; and a green alert (low risk) for Michoacan, Jalisco, and Colima. The outer rainbands brought moderate rains to Guerrero, causing minor flooding in Acapulco. Across the state, the storm generated 24 landslides, which blocked highways. Two people were killed in the Guerrero, one a tourist that drowned in Zihuatanejo and the other a police officer in an airplane crash that injured 19 others. High seas flooded numerous buildings across coastal towns in Colima, damaging 34 tourist facilities and killing one person. Additionally, many restaurants built of wood and coconut were damaged. The port in Manzanillo was closed to small craft, as was the port of Mazatlan. Overall, 50 homes were damaged by the storm. Cosme also brought rough seas and gale force winds to the Revillagigedo Islands.
