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 Maria
Entering the Caribbean Sea, Maria weakened slightly to a Category 4 hurricane due to land interaction with the island of Dominica, however it quickly restrengthened to a Category 5 hurricane and attained its peak intensity with winds of 175 mph (280 km/h) and a pressure of 908 mbar (hPa; 26.81 inHg) at 03:00 UTC on September 20 while southeast of Puerto Rico; this ranks it as the tenth-most intense Atlantic hurricane since reliable records began. An eyewall replacement cycle caused Maria weaken to Category 4 strength before it made landfall near Yabucoa, Puerto Rico at 10:15 UTC (6:15am local time) that day with winds of 155 mph (250 km/h)—the most intense to strike on the island since the 1928 San Felipe Segundo hurricane. Maria weakened significantly while traversing Puerto Rico, but was able to restrengthen to a major hurricane once it emerged over the Atlantic later that afternoon, eventually attaining a secondary peak intensity with winds of 125 mph (205 km/h) on September 22, while north of Hispaniola.
