The hurricane brought strong winds to parts of the Virgin Islands. In Saint Thomas, wires and trees were blown down and homes were damaged. Ships also sank in the Saint Thomas harbor, as well as at Tortola. Property losses on Saint Thomas were estimated to have exceeded $200,000 and 15 people were killed. Most of the damage caused by the San Ciprián hurricane occurred in Puerto Rico, particularly along the island's northern half. The powerful winds caused the destruction of numerous buildings. Over 40,000 homes were destroyed throughout the U.S. territory, contributing to a $15.6 million property damage toll and rendering 25,000 families homeless. Heavy losses were wrought upon crops, particularly to citrus and coffee. The hurricane killed 257 people in Puerto Rico and injured another 4,820. Economic losses stemming from the devastation were equivalent to 20 percent of Puerto Rico's gross income.

Meteorological history

The presence of unusually high air pressures throughout the Atlantic and eastern North America caused the 1932 San Ciprián hurricane to take an atypical path directed towards the west and west-southwest over its duration. Details about the hurricane's genesis are unclear due to a lack of contemporaneous weather observations. In 2012, the Atlantic Oceanographic and Meteorological Laboratory (AOML) investigated the storm's history, determining that the hurricane's progenitor had developed into a tropical storm with sustained winds of 60 mph (97 km/h) by 06:00 UTC on September 25, 1932. At that point, the storm was amid a period of intensification and centered approximately 340 mi (550 km) east of Antigua. Its winds increased as it moved west, reaching hurricane-force by 12:00 UTC on September 25. Early the next day, the hurricane passed near Antigua and Saint Barthelemy, and later between Saint Thomas and Saint Croix, tracking west-northwest at roughly 10 mph (16 km/h). Around 13:00 UTC on September 26, the center of the storm passed near Saba with winds of 140 mph (230 km/h); the steep pressure gradient measured on that island was indicative of a small and rapidly intensifying hurricane.

At around 04:00 UTC on September 27, the compact hurricane made landfall on Puerto Rico near Ensenada Honda in the municipality of Ceiba. Upon moving ashore, the hurricane had sustained winds estimated at 145 mph (233 km/h) and a minimum central pressure of 943 mbar (hPa; 27.85 inHg), equivalent to a Category 4 hurricane on the modern Saffir–Simpson scale. The region of hurricane-force winds was likely no larger than 23 mi (37 km) in diameter upon landfall, with a radius of maximum winds likely smaller than 12 mi (19 km). The storm's center tracked over Puerto Rico for seven hours on an east-to-west course before emerging into the Caribbean Sea off Aguadilla. Land interaction with Puerto Rico caused the storm's maximum winds to decrease to 105 mph (169 km/h); the hurricane maintained this strength until it struck the southern ends of the Dominican Republic and Haiti on September 28. This second landfall weakened the system significantly, reducing the winds to 45 mph (72 km/h). The storm took a slightly south of west heading for the rest of its duration, passing near Jamaica on September 29. According to the AOML, the storm might have weakened to a tropical depression between September 29–30 while traversing the western Caribbean. The tropical storm reorganized slightly upon making its final landfall south of Belize City in British Honduras at around 18:00 UTC on October 1 with winds of 45 mph (72 km/h). It progressed west-southwest into southeastern Mexico, weakening before dissipating on October 2.
