== Connection to tropical cyclones ==
Before the advent of [[Tropical cyclone naming|standardized naming of tropical storms and hurricanes]] in the [[Tropical cyclone basins|North Atlantic basin]], [[tropical storm]]s and [[Atlantic hurricane|hurricanes]] that affected the island of [[Puerto Rico]] were informally named after the Catholic saints corresponding to the feast days when the cyclones either made landfall or started to seriously affect the island. Examples are: the 1780 San Calixto hurricane (more widely known as the [[Great Hurricane of 1780]], the deadliest in the North Atlantic basin's [[recorded history]]; named after [[Pope Callixtus I]] (Saint Callixtus), whose feast day is October&nbsp;14),<ref name=Mujica>{{Cite report|first=Frank|last=Mújica-Baker|title=Huracanes y tormentas que han afectado a Puerto Rico|publisher=Estado Libre Asociado de Puerto Rico, Agencia Estatal para el Manejo de Emergencias y Administración de Desastres|url=http://www.gobierno.pr/NR/rdonlyres/49EA64D0-305B-4881-8B85-04B518004BD5/0/Ciclones_en_PR.pdf|pages=4, 7–10, 12–14|language=es|access-date=October 12, 2018|archive-date=24 September 2015|archive-url=https://web.archive.org/web/20150924022947/http://www.gobierno.pr/NR/rdonlyres/49EA64D0-305B-4881-8B85-04B518004BD5/0/Ciclones_en_PR.pdf|url-status=dead}}</ref> the [[1867 San Narciso hurricane]] (named after Saint [[Narcissus of Jerusalem]], feast day October&nbsp;29),<ref name=Mujica/> the [[1899 San Ciriaco hurricane]] (the deadliest in the island's recorded history; [[Saint Cyriacus]], August&nbsp;8),<ref name=Mujica/><ref>{{cite web|url=https://www.ecu.edu/renci/StormsToLife/SanCiriaco/index.html|title=San Ciriaco Hurricane|work=East Carolina University, RENCI Engagement Center|access-date=12 October 2018|archive-date=19 October 2019|archive-url=https://web.archive.org/web/20191019002209/https://www.ecu.edu/renci/StormsToLife/SanCiriaco/index.html|url-status=dead}}</ref> the [[1928 San Felipe hurricane]] (the strongest in terms of measured wind speed; [[September 13 (Eastern Orthodox liturgics)#Pre-Schism Western Saints|Saint Philip]], father of Saint [[Eugenia of Rome]], September&nbsp;13),<ref name=Mujica/> and the [[1932 San Ciprian hurricane]] ([[Cyprian and Justina|Saint Cyprian]], September&nbsp;26).<ref name=Mujica/>

This practice continued until quite some time after the [[United States Weather Bureau]] (now called the National Weather Service) started [[History of tropical cyclone naming|publishing and using official female human names]] (initially; male names were added starting in 1979 after the NWS relinquished control over naming to the [[World Meteorological Organization]]). The last two usages of this informal naming scheme in Puerto Rico were in 1956 ([[Hurricane Betsy (1956)|Hurricane Betsy]], locally nicknamed Santa Clara after Saint [[Clare of Assisi]], feast day August&nbsp;12 back then; her feast day was advanced one day in 1970) and 1960 ([[Hurricane Donna]], nicknamed San Lorenzo after Saint [[Lawrence Giustiniani|Lawrence Justinian]], September&nbsp;5 back then; feast day now observed January&nbsp;8 by [[Canons regular]] of St. [[Augustine of Hippo|Augustine]]).<ref name=Mujica/>
