1899 San Ciriaco hurricane
The hurricane weakened slightly while moving west-northward across the Caribbean Sea and made landfall in Guayama, Puerto Rico late on August 8 with winds of 140 mph (220 km/h). August 8 was the namesday of Saint Cyriacus, hence the hurricane's nickname. Several weather stations across the island reported low barometric pressures, with a reading as low as in Guayama. Wind shifts were also experienced across the island, primarily in the south and the west. The storm crossed Puerto Rico in approximately six hours and emerged into the Atlantic Ocean late on August 8, while weakening to a Category 3 hurricane, with winds decreasing to 120 mph (195 km/h). The hurricane would maintain this intensity for more than nine days. Continuing west-northward, the hurricane brushed the north coast of Dominican Republic on August 9. Thereafter, the system moved slowly northwestward through the Bahamas, striking Inagua on August 10 and Andros Island on August 12. According to telephone and telegraph reports from the Weather Bureau, the storm was predicted to make landfall in Florida.
Hurricane Hortense
By early on September 9, Hortense was upgraded to a hurricane, while curving northwestward. Around 0600 UTC on the following day, the storm made landfall near Guánica, Puerto Rico with winds of 80 mph (130 km/h); this made it the first hurricane landfall on the island since Hurricane Hugo in 1989. Initially, most tropical cyclone forecast models anticipated Hortense would pass south of the island and instead strike the Dominican Republic. After two hours, Hortense emerged into the Mona Passage and brushed the eastern tip of Dominican Republic; Punta Cana near the eastern tip of the country reported the calm of the eye on September 10. Land interaction with Hispaniola weakened the storm slightly, though it would soon re-strengthen.
