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.
Meteorological history of Hurricane Maria
The hurricane made its closest approach to St. Croix at around 05:00 UTC on September 20, passing within 20 mi (30 km) of the island; the storm's outer eyewall lashed the island while the more violent inner eye remained offshore. Three hours later, at around 08:00 UTC, the outer eyewall struck Vieques, an island off the eastern coast of Puerto Rico. By this time, the outer eyewall became dominant as the inner one decayed, and the eyewall replacement cycle caused Maria weaken to Category 4 strength. Maria made landfall near Yabucoa, Puerto Rico, at 10:15 UTC, with winds of 155 mph (250 km/h) and a central pressure of 920 mbar (hPa; 27.17 inHg), making it the strongest to hit the island since the 1928 San Felipe Segundo hurricane, which had struck Puerto Rico as a Category 5 hurricane. Additionally, when Maria made landfall in Puerto Rico as a Category 4 storm, following the landfalls of Harvey and Irma, it marked the first time that three Category 4 hurricanes made landfall in the United States within a year, including unincorporated territories.
