San Felipe II, September 13, 1928

September 13 is the feast of San Felipe. The island already had a San Felipe in 1876, so the 1928 cyclone became San Felipe the Second. The National Hurricane Center's deadliest cyclones table lists it as Puerto Rico, San Felipe, 1928, Category Five, 312 deaths. That is the published pair this essay uses: intensity class and death count just as the Center still prints them.

NHC appendix: Puerto Rico (San Felipe) 1928, Category Five, 312. María's death counts are a later and separate problem.

The eye crossed from the southeast near Guayama and exited between Aguadilla and Isabela after hours over land. San Juan's anemometer reported extreme sustained winds before failing. A ship off the south coast recorded a pressure low enough to sustain a Category Five lashing on the Saffir-Simpson scale, a label applied later to a storm people then knew only by the saint and the sound. Towns near the eye were flattened. The agricultural loss ran through cane and coffee.

San Felipe the Second is the storm later chroniclers name when they say María was the strongest hit to Puerto Rico since 1928. That sentence is about wind and pressure at landfall, not about how the dead were counted. The 312 on the Center's list are a contemporary certified count of the kind civil records could still attempt in a slower disaster. It is not an excess-deaths study.

The hurricane went on to Florida's Lake Okeechobee, where the mainland count dwarfed the island's. Puerto Rican memory of the storm stayed local: roofs gone, cane crushed, a generation that dated houses as before or after Felipe. When the Weather Bureau and later the Hurricane Center ranked the Atlantic killers, the island line stayed in the appendix, apart from Galveston and Katrina, but not forgotten.

Do not import María's three-layer math into this record. The 2017 TCR comparison is about Category and pressure, not about Harvard or Milken.

What remains on the public page is modest and hard: Category Five in Puerto Rico, 312 dead. That suffices. The rest of the island's hurricane file — Ciprián, Santa Clara, Hugo, Georges, María, Fiona — lives in later lessons with their own dates and their own sources.
