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.
1932 San Ciprian hurricane
Offshore, the rough seas brought by the hurricane caused heavy damage to shipping as the storm surge caused two boats to run aground near Ceiba. In San Juan, two more boats sustained severe damage. The storm surge and high winds also damaged or destroyed several warehouses. Elsewhere in Puerto Rico, the damage was even more severe as the hurricane's high winds destroyed many homes in outlying villages killing 109 people. The highest death toll came from the town of Rio Piedras which was directly in the path of the hurricane and many of the homes were in poor condition to withstand the hurricane's winds. Damage to roads, power lines, and roads disrupted communications and access to the interior portion of Puerto Rico. Heavy rainfall from the hurricane caused significant flooding that left many homes and buildings under 1.5 feet (0.4 meter) of water.
