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 Cleo
Moderate to heavy rains fell across Puerto Rico, peaking at 4.95 inches (125.7 mm) at Matrullas Dam. The outer bands of Cleo produced peak sustained winds of 52 mph (85 km/h) at Point Tuna, Puerto Rico. Offshore Puerto Rico on its initial penetration of Cleo on August 23, a Lockheed WC-121N Super Constellation used as a reconnaissance aircraft experienced its port wing tip fuel tank and portion of wing torn away by extreme updraft turbulence, which injured six of its crew. While trying to exit the storm, the starboard tip tank and larger portion of wing were torn away by extreme down draft turbulence. The aircraft was damaged beyond repair. Cleo led to the wettest known 24‑hour period recorded for any site within the Dominican Republic for any month, with 19.99 inches (507.8 mm) falling at Polo. Les Cayes, Haiti was leveled as the storm struck the town. The aircraft carrier U.S.S. Boxer arrived off the coast of Hispaniola on August 29 to provide medical aid and evacuation services to those in the worst impacted areas of Haiti and the Dominican Republic. Damage in Cuba was minimal because the hurricane had weakened and moved through quickly.
