Puerto Rico is an archipelago of 143 islands that is part of the Greater Antilles and located in the northeast Caribbean, west of the Lesser Antilles chain. In five centuries of recorded history, it has experienced the effects of more than 150 Atlantic hurricanes, or storms that were once tropical or subtropical cyclones. Prior to this, these systems were responsible shaping the mythology of the Pre-columbian civilizations of the region, including the Taíno.
The passing of hurricanes over Puerto Rico is noted to be cyclical, often experiencing prolonged periods of inactivity and then a sudden impact by multiple storms. [1] The combination of this with recurrent droughts, show how the effects of El Niño and La Niña historically affected the region. In general, the storms that strike during the early months are usually weaker than those in September and October. [2]
During pre-Columbian times, the term juracán was used by Taínos, and it is believed that the Europeans later adapted it into "huracán" or hurricane. [3] The storms shaped the native traditions and lyfestyle, with a heavy presence in their mythology. However, there is no definite record of this period, with the first hurricane formally recorded in the West Indies being the one later responsible for sinking the Bobadilla fleet in the Mona Passage. [4]
On August 16, 1508, Juan Ponce de León reported a storm, which marked decades were these events were reported but not designated due to the inexistence of a naming tradition that early. [4] San Bartolomé broke a nine year hiatus, with Coll y Toste dating it to August 24, 1568. [5] This event lead to the origin of the legend of the miracle of Nuestra Patrona de Guadalupe. [5] It is believed that this was the first phenom officially named after a Catholic saint. [5] Afterwards, a system based on the Spanish variant and honorific of the Saint of the Month was installed, with the day of passing determining the name associated with it. Consequently, many hurricanes of the Spanish period were retroactively named, with the first becoming known as San Roque. [4] Damián López de Haro/Torres Vargas was responsible for the documentation of San Leoncio I and also Santa Cruz. [6]
The first barometric measurement recorded in Puerto Rico took place on August 2, 1837, as Nuestra Señora de Los Ángeles entered, allowing the subsequent classification of it as a Category 2 hurricane. [7] In the coast it caused at least 37 shipwrecks that killed passengers. Rain gauging following soon afterwards. [8] Despite being scientifically studied, the impact of San Evaristo/San Narciso, which happened on October 26, 1853, was mostly salvaged from oral tradition by Víctor Coll y Cuchí. [9] Meteorological study continued solidifying during this time, influenced by the recurrent storms and a series of earthquakes, reaching the masses through the newspapers El Eco and La Gaceta. [8]
The Oficina del Servicio Meteorológico was subsequently established, and amateur research became popular. The adjacent passage of Santa Juana put a system of telegraph emergency response to the test. [10] By this time, the scientific study of the hurricanes and the effect of La Seca (a recurrent period of drought) and post-passage plagues had begun, leading to the first hypotheses. [11] Among jíbaros, a belief that hurricanes followed droughts had emerged from their direct observation of these events, paving the way for these studies. [12] Academically, Caribbean hurricanes have been recorded in literature since at least Benito Vinez in 1877. [13] Subsequent work was published by Vicente Fontan y Mera (San Narciso) in 1878. [14]
The nascent Departamento del Negociado del Tiempo took over the study of storms during the 20th Century. [15] As meteorology advanced and new technologies were introduced, the study and documentation of hurricanes in the region improved significantly. [16] So did the public awareness of their trajectory, facilitated with maps provided in the local media. Aruez y Fernando continued the documentation of hurricanes in 1905 (San Ciriaco). [14] Cayetano Coll y Toste and José Julián Acosta recorded their own lists of cyclones to hit Puerto Rico. [14] Rafael Ramírez's 1932 Los Huracanes en Puerto Rico gave exclusivity to the topic. [14] Luis Salivia would publish a similar work in 1950. [14] Pio Medrano examined the witness documentation listing the effects of several hurricanes and was also responsible for finding the exact date of Santa Cruz. [17] [18]
The name classification was changed, as the religious system used since Spanish times systematically made way for the American system. On August 12, 1956, Category 1 hurricane Betsy was the first to be classified in this manner, tough its traditional name of Santa Clara was still widely used, causing 16 deaths and notable building/agricultural losses in a quick traverse. [19] This was also the first storm recorded by radar in Puerto Rico. [20] In 1995, Edwin Miner published Historia de los Huracanes en Puerto Rico. [14] In the 21st century, Pío Medrano and Stuart Schwarts further elaborated on the matter. [14]
From the beginning of the Spanish colonization, the constant influx of storms in the region made the Europeans consider leaving the island, partly due to being caught unprepared for the extent of their effects. [6]
