Tropical Storm Trudy was a short-lived tropical cyclone in October 2014 that caused significant flooding in southern Mexico. The storm originated from an area of low pressure associated with a monsoon trough near Central America in early October. A slow-moving system, the low eventually consolidated into a tropical depression on October 17 near the Mexican coastline. Favorable environmental conditions aided rapid development of Trudy. Within 15 hours of its designation, an eye formed over the storm's center. Trudy ultimately achieved its peak intensity as a strong tropical storm with 65 mph (100 km/h) winds as it made landfall just southeast of Marquelia, Mexico. The region's mountainous terrain quickly weakened Trudy and the cyclone dissipated early on October 19. Though the cyclone dissipated, its remnant energy later contributed to the formation of Tropical Storm Hanna in the Atlantic.

The 2014 Atlantic hurricane season was a below-average hurricane season in terms of named storms and major hurricanes, though average in terms of number of hurricanes overall. It produced nine tropical cyclones, eight of which became named storms; six storms became hurricanes and two intensified further into major hurricanes. The season officially began on June 1, and ended on November 30. These dates historically describe the period each year when most tropical cyclones form in the Atlantic basin. The first storm of the season, Arthur, developed on July 1, while the final storm, Hanna, dissipated on October 28, about a month prior to the end of the season.
