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.

The storm weakened after moving inland and fell to Category 1 intensity by 1200 UTC on August 18. Later that day, the storm re-emerged into the Atlantic. Now heading northeastward, it continued weakening, but maintained Category 1 intensity. By late on August 20, the storm curved eastward over the northwestern Atlantic. It also began losing tropical characteristics and transitioned into an extratropical cyclone at 0000 UTC on August 22, while located about 325 miles (525 km) south of Sable Island. However, after four days, the system regenerated into a tropical storm while located about 695 miles (1,120 km) west-southwest of Flores Island in the Azores on August 26. It moved slowly north-northwestward, until curving to the east on August 29. Between August 26 and September 1, the storm did not differentiate in intensity, but began re-strengthening while turning southeastward on September 2. Early on the following day, the storm again reached hurricane intensity. It curved northeastward and passed through the Azores on September 3, shortly before transitioning into an extratropical cyclone.
