The 1959 Mexican Hurricane was a devastating tropical cyclone that was one of the worst Pacific hurricanes ever. It impacted the Pacific coast of Mexico in October 1959. It killed at least 1,000 people, and perhaps double that, a record that still stands, and caused at least 280 million dollars in damage. The system's worst impact was in the Mexican States of Colima and Jalisco due to high winds, and flooding. This hurricane was also a Category 5 on the Saffir-Simpson Hurricane Scale and set several records, related to both impact and meteorological statistics.
