1899 San Ciriaco hurricane
Hurricane San Ciriaco set many records on its path. Resulting in at least 3,369 deaths in Puerto Rico, the storm was the deadliest hurricane to hit the island and the strongest at the time, until the Hurricane San Felipe Segundo made landfall in 1928 as a Category 5 hurricane. It was also among the deadliest Atlantic hurricanes ever recorded.
Hurricane Willa
Afterward, Willa underwent rapid intensification, strengthening into a strong tropical storm by 03:00 UTC on October 21. Six hours later, at 09:00 UTC, Willa became a Category 1 hurricane. Further rapid intensification ensued; by 15:00 UTC on the same day, Willa had attained Category 2 status, while turning northward. Subsequently, the storm strengthened into a Category 3 major hurricane at 21:00 UTC, becoming the tenth major hurricane of the season. At 22:30 UTC, Willa intensified further into a Category 4 hurricane. Willa reached Category 5 status at 15:00 UTC on the next day, becoming the third Category 5 hurricane of the season, and the storm achieved its peak intensity, with a minimum central pressure of and maximum 1-minute sustained winds of . Around the same time, microwave satellite imagery detected the presence of an outer eyewall, indicating that Willa was beginning to undergo an eyewall replacement cycle. Willa also began to interact with the smaller Tropical Storm Vicente to the southeast at about this time. Several hours later, Willa's eyewall replacement cycle took a toll on the storm, and the system weakened to a high-end Category 4 hurricane at 21:00 UTC, with its smaller eye becoming cloud-filled. Afterward, Willa encountered increasing wind shear and weakened further to Category 3 intensity, by 15:00 UTC on October 23, while turning northeastward. Soon afterward, Hurricane Willa absorbed the remnants of Tropical Storm Vicente into its circulation. At 18:00 UTC, the center of Willa passed over the Islas Marías, at Category 3 intensity. A few hours later, Willa completed its eyewall replacement cycle, and the storm's intensity stabilized, while gradually accelerating towards the northeast. At 01:00 UTC on October 24 (7:00 pm on October 23, local time), Willa made landfall as a Category 3 hurricane in , in the municipality of Escuinapa, Sinaloa, with 1-minute sustained winds of 120 mph (195 km/h). Following landfall, mountainous terrain and southwesterly wind shear took a toll on the storm's strength, and Willa rapidly weakened, degenerating into a tropical storm by 06:00 UTC on October 24. Willa continued to weaken as it accelerated northeastward, and the storm dissipated at 15:00 UTC over northeastern Mexico, as the storm's surface circulation had dissipated.
