Hurricane Manuel brought widespread flooding across much of Mexico in September 2013, in conjunction with Hurricane Ingrid. The fifteenth named storm and seventh hurricane of the annual hurricane season, Manuel originated from a strong area of low pressure south of Acapulco on September 13. Within favorable conditions aloft, the storm intensified into a tropical storm as it tracked northward. The following day, Manuel curved westward and strengthened to a point just shy of hurricane intensity before making its first landfall at that intensity on September 15. Due to interaction with land, the tropical storm quickly weakened, and its center dissipated over western Mexico on September 16. However, the storm's remnants continued to track northwestward into the Gulf of California, where they reorganized into a tropical cyclone the next day. Manuel regained tropical storm status on September 18 as it began to curve northeastward. Shortly thereafter, Manuel attained Category 1 hurricane intensity, before making its final landfall just west of Culiacán at peak intensity. Over land, Manuel quickly weakened due to interaction with Mexico's high terrain, and the storm dissipated early on September 20.

The 2013 Pacific hurricane season was an above average Pacific hurricane season with 21 tropical cyclones forming. Of these, 20 became named storms – 18 in the Eastern Pacific basin, and 2 in the Central Pacific basin. Of the 18 named storms in the east, 9 became hurricanes, with one, Raymond, becoming the season's only major hurricane. In the central, neither named storm became a hurricane. It was also a below-normal season in terms of Accumulated cyclone energy (ACE), as many of its systems were weak and short-lived. The season officially began on May 15 in the Eastern Pacific and started on June 1 in the Central Pacific; both ended on November 30. These dates conventionally delimit the period of each year when most tropical development occurs in these North Pacific basins. The first cyclone, Tropical Storm Alvin, formed on May 15, and the last, Tropical Storm Sonia, dissipated on November 4.
