1899 San Ciriaco hurricane
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 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.
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 .
