the storm and was lost, with all eleven crew members believed perished. This was the only such loss which has occurred in association with an Atlantic hurricane. A Category 5 upon landfall on the Yucatán Peninsula, Janet caused severe devastation in areas on Quintana Roo and British Honduras. Only five buildings in Chetumal, Mexico remained intact after the storm. An estimated 500 deaths occurred in the Mexican state of Quintana Roo. At Janet's second landfall near Veracruz, significant river flooding ensued, worsening effects caused by Hurricanes Gladys and Hilda earlier in the month. The floods left thousands of people stranded and killed at least 326 people in the Tampico area. The flood damage would lead to the largest Mexican relief operation ever executed by the United States. At least 1,023 deaths were attributed to Hurricane Janet, as well as $65.8 million in damages. Tropical Storm Eleven A tropical wave moved off the coast of Africa on September 18 and continued west-northwestward. It is possible that the system developed into a tropical depression the next day, although lack of data prevented such classification until September 23, when a nearby ship reported winds of . An approaching cold front turned the system to the north on September 24. The structure gradually became better organized, and after turning to the northeast on September 26, the depression intensified into a tropical storm. This was based on a ship report of winds, which was also estimated as the system's peak intensity. On September 27, the system became extratropical and accelerated its forward motion, dissipating within a larger extratropical storm south of Iceland on the next day. Tropical Storm Twelve A tropical wave was reported to have passed through Cape Verde on October 4. The system slowly developed a vertex as it curved in a generally northward direction. By early on October 10, two ships reported that a tropical depression formed almost halfway between the Azores and the Leeward Islands. After six hours, the depression strengthened into a tropical storm. While re-curving to the northeast, the storm attained its maximum sustained winds of ; the lowest atmospheric pressure recorded in relation to the storm was , but the time of measurement is unknown. Although no significant weakening occurred, it eventually merged with an extratropical cyclone on October 14, while still well southwest of the Azores. During its extratropical stage, a ship in the area reported an
