context_page_description: The 1899 San Ciríaco hurricane, also known as the 1899 Puerto Rico Hurricane or The Great Bahamas Hurricane of 1899, was the longest-lived Atlantic hurricane on record, and the second-longest-lived tropical cyclone globally on record after 1994's Hurricane John in the Pacific. It was also one of the deadliest Atlantic hurricanes in recorded history, with an estimated 3,800 fatalities. The third tropical cyclone and first major hurricane of the season, this storm was first observed southwest of Cape Verde on August 3. It slowly strengthened while heading steadily west-northwestward across the Atlantic Ocean and reached hurricane status by late on August 5. During the following 48 hours, it deepened further, reaching Category 4 on the modern day Saffir–Simpson hurricane wind scale before crossing the Leeward Islands on August 7. Later that day, the storm peaked winds of 150 mph. The storm weakened slightly before making landfall in Guayama, Puerto Rico with winds of 140 mph on August 8. Several hours later, it emerged into the southwestern Atlantic as a Category 3 hurricane.
context_section_description: A tropical storm of unknown origins developed about 480 miles (770 km) southwest of the southwestern-most islands of Cape Verde at 00:00 UTC on August 3. According to an article by the United States Hydrographic Office, the British steamship Grangense encountered the system later that day, while located about 1,800 miles (2,900 km) east-southeast of Guadeloupe. According to the ship's log, there was a "sudden change in the weather", falling barometric pressures, and increasingly rough seas. Further, the storm "showed all the symptoms of a genuine West Indian hurricane underdeveloped." The captain, who followed a route from Europe to Brazil for many years, noted that he never experienced "any weather of cyclonic character so far to the eastward before".
  Thereafter, the storm strengthened and reached winds of 70 mph (110 km/h) early on August 4. Intensification halted until late on the following day, at which time the storm reached hurricane status. Around 18:00 UTC on August 6, it became a Category 2 hurricane. Early the next day, the system deepened to a Category 3. While approaching the Lesser Antilles, it continued to strengthen, reaching Category 4 status around midday on August 7. Shortly thereafter, the hurricane passed through the Lesser Antilles and made landfall on Guadeloupe. At 18:00 UTC on August 7, the system attained its peak intensity with a maximum sustained wind speed of 150 mph (240 km/h) and a minimum barometric pressure of 930 mbar (27 inHg), observed by a weather station on Montserrat.
  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 939 mbar (27.7 inHg) 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. 
  However, the storm instead curved north-northwestward and struck Grand Bahama on August 13. The next day, officials at the Weather Bureau predicted that the hurricane would strike Charleston, South Carolina, at which time it would have weakened "into an ordinary blow". 
  Instead, the storm eventually turned northeastward and moved parallel to the coast of the Southeastern United States for a few days. By early on August 17, however, the hurricane re-curved northwestward. At 01:00 UTC on August 18, it made landfall near Hatteras, North Carolina, with winds of 120 mph (195 km/h). Five hours later, the storm weakened to a Category 2 hurricane. Around midday on August 18, it fell to Category 1 hurricane intensity while re-emerging into the Atlantic Ocean. Thereafter, the storm drifted slowly east-northeastward before accelerating to the northeast after 12:00 UTC on August 19. It moved parallel to Long Island and New England, until curving just north of due east late on the following day.
  The system began losing tropical characteristics after interacting with a weather front and transitioned into an extratropical cyclone early on August 22, while situated about 325 miles (525 km) south of Sable Island, Nova Scotia. The extratropical system moved east-southeastward and then southeastward, while continuing to weaken. By August 24, it curved eastward and then northeastward the next day. Operationally, it was believed that the system remained ext
