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 Diana
The new tropical depression moved to the northwest under the influence of a mid-level trough, and rapidly intensified to a tropical storm the following day offshore of eastern Honduras; the National Hurricane Center assigned the name Diana to the system. Becoming a tropical storm, Diana further intensified, and winds reached 65 mph (105 km/h) before landfall in Felipe Carrillo Puerto in Quintana Roo occurred. The storm initially rapidly weakened over land, although it retained winds of 50 mph (80 km/h) until moving over open waters. When Diana entered the southern Gulf of Mexico, the trough of low pressure in that vicinity weakened and steering currents caused the storm to head westward. Conditions became more favorable in the Gulf of Mexico, and Diana quickly intensified, becoming a hurricane late on August 7. Hurricane Diana rapidly intensified, and briefly reached Category 2 hurricane status, attaining peak intensity with winds of 100 mph (165 km/h) and a minimum barometric pressure of 980 mbar (hPa; 28.94 inHg). Only two hours after attaining peak intensity on August 7, Hurricane Diana made landfall near Tampico, Tamaulipas at the same intensity.
