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.
Hurricane Otto
On November 12, the National Hurricane Center (NHC) first noted the potential for a low pressure area to develop in the southwestern Caribbean Sea, assessing a low probability for tropical cyclone formation within five days. After a convectively coupled Kelvin wave and several nearby tropical waves interacted with each other in the aforementioned area, atmospheric pressure in that region began falling on November 14, resulting in a broad low pressure area forming north of Colombia on November 15. The low moved slowly and erratically, with a disorganized structure and light winds, disrupted by unfavorable upper-level conditions. On November 19, the convection increased and became better organized, amid marginally favorable conditions. The Hurricane Hunters flew into the system on November 20, observing a well-defined circulation, and the system became a tropical depression at 18:00 UTC that day.
The nascent depression meandered over the southwestern Caribbean Sea, its path to the north blocked by a ridge. Thunderstorm activity continued to pulse over the center, and the inner core of convection became more organized. The depression intensified into a tropical storm by 06:00 UTC on November 21, receiving the name "Otto". The storm had well-established outflow to the northeast, fueled by warm water temperatures of around . After the convection organized into a central dense overcast, Otto became a strong tropical storm with 70 mph (110 km/h) winds, and maintained that intensity for about a day. On November 23, the storm reached hurricane intensity, and began a period of rapid intensification, reaching Category 2 intensity by 06:00 UTC the following day, with winds of 105 mph (165 km/h). Six hours later, Otto reached its peak intensity as a Category 3 major hurricane with winds of 115 mph (185 km/h), becoming the latest major hurricane on record in the satellite era. At 17:30 UTC, Otto made landfall over the Indio Maíz Biological Reserve in southeastern Nicaragua, roughly northwest of the Nicaragua–Costa Rica border at peak intensity. This marked the southernmost landfall of a hurricane in Central America since reliable records began, eclipsing Hurricane Irene–Olivia of 1971 by .
