Hurricane John was a powerful tropical cyclone that caused deadly flooding across southern Mexico for several days in September 2024. The eleventh named storm, fourth hurricane, and second major hurricane of the 2024 Pacific hurricane season, John originated from a low-pressure area offshore Southern Mexico. This low developed into Tropical Depression Ten‑E on the afternoon of September 22, strengthening into Tropical Storm John the following morning. Undergoing rapid intensification, John strengthened from a moderate tropical storm into a Category 3 hurricane on September 24. It was at that intensity that John made landfall in Marquelia, Guerrero, later that day. Once inland, John rapidly weakened, dissipating over Mexico later that day. However, the mid-level remnants of John moved back over the ocean, where favorable conditions enabled John to redevelop. On September 27, after again becoming a minimal hurricane, Tropical Storm John made its second landfall, this time near Tizupan, Michoacán. Hours later, it dissipated for a final time over the coastal mountains.
John resulted in strong winds, significant flooding, and numerous mudslides across much of coastal southwestern Mexico. A total of 950 mm (37 in) of rain fell across parts of Guerrero, with similarly extreme rainfall in neighboring Oaxaca and Michoacán. More than 98,000 people lost power in Oaxaca. As of September 28, twenty-nine deaths have been reported in association with John.
