Hurricane Dolores formed as a tropical disturbance south of Mexico on June 13, 1974. It became a tropical storm on June 14 and quickly organized, developing an eye-like feature. Dolores reached hurricane strength by June 16, with maximum sustained winds near 80 mph (130 km/h) and a central pressure around 973 mb. It made landfall near Acapulco about 18 hours after that and dissipated by June 17. Dolores was considered the worst hurricane to hit Acapulco since 1938.

Across southwestern Mexico, Dolores brought heavy rain, flooding, and mudslides. Rivers overflowed, roads were damaged, and some areas were cut off. Near Acapulco, about 30 homes were destroyed and the low-lying suburbs saw many people injured or left homeless (about 600). Overall, 18 people were killed (with reports up to 28), 32 were injured, and roughly 173,000 people were affected. Landslides in nearby rural mountains killed about nine more people. Offshore, six people were missing after their trawler was caught in the storm. The damage was about $4 million in 1974 dollars. The Mexican Army distributed relief supplies in Oaxaca to help those affected.
