tropical storm over southeastern Cuba, the system re-strengthened into a hurricane as it struck Grand Cayman early on September 15. The storm intensified further over the northeastern Caribbean, becoming a Category 3 major hurricane and reaching sustained winds of about 24 hours later. Late on September 16, Hilda struck a sparsely-populated region of the eastern Yucatán Peninsula, causing light damage. Although Hilda quickly weakened to a tropical storm over the Yucatán Peninsula, the cyclone re-strengthened to again reach winds of early on September 19. Before the hurricane moved ashore, there was residual flooding in Tampico from earlier Hurricane Gladys. Hilda struck the city early on September 19 and then rapidly weakened inland, dissipating on September 20. The storm is estimated to have generated gusts up to and dropped heavy rainfall that flooded 90% of Tampico, while its strong winds damaged half of the homes, leaving 15,000 homeless. Throughout Mexico, 11,432 people were directly affected by Hilda. Overall, the storm killed 300 people and caused over $120 million in damages. Additionally, the outer bands of Hilda caused minor flooding in southern Texas, particularly in Raymondville. Hurricane Janet Hurricane Janet was the most powerful tropical cyclone of the season and one of the strongest Atlantic hurricanes on record. The hurricane formed from a tropical wave east of the Lesser Antilles on September 21. Moving toward the west across the Caribbean Sea, Janet fluctuated in intensity, but generally strengthened before reaching its peak intensity as a Category 5 hurricane on the Saffir–Simpson hurricane scale with winds of . The intense hurricane made landfall at that intensity near Chetumal, Mexico on September 28. Janet's landfall as a Category 5 hurricane on the Yucatán Peninsula marked the first recorded instance that a storm of such intensity in the Atlantic basin made on a continental mainland, with all previous storms making landfall as Category 5 hurricanes on islands. After weakening to a Category 2 over the Yucatán Peninsula, it moved into the Bay of Campeche and remained mostly unchanged in intensity before making its final landfall near Veracruz on September 29. Janet quickly weakened over Mexico's mountainous terrain before dissipating on September 30. In its developmental stages near the Lesser Antilles, Janet caused significant damage to the island chain, resulting in 189 deaths and $7.8 million in damages in the Grenadines and Barbados. While Janet was in the central Caribbean Sea, a reconnaissance aircraft flew into
