1899 San Ciriaco hurricane
1899 San Ciriaco 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 (in terms of tropical duration) after Hurricane John in the Pacific. 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 (SSHWS) before crossing the Leeward Islands on August 7. Later that day, the storm peaked winds of 150 mph (240 km/h). The storm weakened slightly before making landfall in Guayama, Puerto Rico with winds of 140 mph (220 km/h) on August 8. Several hours later, it emerged into the southwestern Atlantic as a Category 3 hurricane. The system paralleled the north coast of Dominican Republic and then crossed the Bahamas, striking several islands. Thereafter, it began heading northward on August 14, while centered east of Florida. Early on the following day, the storm re-curved northeastward and appeared to be heading out to sea. However, by August 17, it turned back to the northwest and made landfall near Hatteras, North Carolina early on the following day. No stronger hurricane has made landfall on the Outer Banks since the San Ciriaco hurricane.
1909 Velasco hurricane
A tropical depression was first noted at 1200 UTC on July 13, northeast of Grenada in the Windward Islands, with winds of , though whether it had a closed circulation at the time remains unclear. Nonetheless, the system remained a weak tropical depression for much of its early existence as it moved to the west-northwest through the eastern Caribbean Sea. Weather reports throughout the Caribbean during this time were sparse and according to José Partagás, a former meteorologist at the National Hurricane Center, the system still may have not formed a closed circulation. This meant that the low was not classifiable, though the lack of data also meant that there was no evidence to support this claim and the system was kept as a tropical depression in HURDAT, the Atlantic Hurricane Database. However, once the depression was located south of Jamaica, it began to slowly strengthen and curve more towards the northwest, reaching tropical storm intensity by 0000 UTC on July 17. At the time, the system was expected to make landfall on the Yucatán Peninsula. Ships in the vicinity of the storm reported strong breezes associated with low barometric pressure. Despite predictions, the system curved from its initial west-northwest movement and more towards the northwest, towards the central Gulf of Mexico. The tropical storm continued to intensify, attaining hurricane strength as a Category 1 hurricane on the Saffir–Simpson Hurricane Scale at 1800 UTC on July 18 after skirting past the Guanahacabibes Peninsula.
