After a center fix was made by another reconnaissance flight and satellite imagery, as well as a ship observing winds of , the system was classified as Tropical Depression Four at 06:00 UTC on August 19, while situated about west-southwest of South Negril Point, Jamaica. With an initially poorly-defined circulation, the depression moved west-northwestward. Because it developed near a mid to upper-level anticyclone, conditions were favorable for intensification, with the system becoming Tropical Storm Dolly around 18:00 UTC on August 19. Convection became more organized, and the storm strengthened into a Category 1 hurricane on the Saffir–Simpson hurricane wind scale just under twenty four hours later. At 17:30 UTC on August 20, Dolly made landfall near Punta Herrero, Quintana Roo – located northeast of Chetumal, with winds of 75 mph (120 km/h). Early the following day, the hurricane weakened to a tropical storm, and then to a tropical depression several hours later. Late on August 21, Dolly emerged into the Bay of Campeche, with satellite imagery indicating that convection was displaced to the south of the center of circulation. However, the system soon began to restrengthening, regaining tropical storm intensity by 00:00 UTC on August 22. Early on the following day, the cyclone began turning westward. At 12:00 UTC on August 23, Dolly reintensified into a hurricane and attained its peak intensity with maximum sustained winds of 80 mph (130 km/h) and a minimum barometric pressure of . Simultaneously, the hurricane made landfall between Tuxpan, Veracruz, and Tampico, Tamaulipas. Six hours after moving inland, Dolly weakened to a tropical storm. Early on August 24, the system deteriorated to a tropical depression. Dolly remained intact while crossing Mexico and emerged into the Pacific Ocean several hours later, but was not reclassified as an eastern Pacific tropical cyclone and dissipated about 40 mi (65 km) west of San Juanito in the Islas Marías. Preparations At 18:00 UTC on August 19, a tropical storm warning was issued from Chetumal to Progreso, Yucatán, while a tropical storm watch was placed between Pinar del Río Province and Isle of Pines, Cuba. Just three hours later, another tropical storm warning was put into effect between San Pedro Town, Belize, and the Mexican border. On August 20, the tropical storm watch was discontinued for Cuba, as the system was moving away from the area. At 15:00 UTC, another tropical storm warning was issued from Progreso, Yucatán, to
