Juracán is the phonetic name given by the Spanish colonizers to the zemi or deity of chaos and disorder that the Taíno natives in Puerto Rico, Hispanola, Jamaica and Cuba, as well as the Island Caribs and Arawak natives elsewhere in the Caribbean, believed controlled the weather, particularly hurricanes. In actuality, the word "juracán" merely represented the storms per se, which according to Taíno mythology were spawned and controlled by the goddess Guabancex. The Taínos were aware of the spiraling wind pattern of hurricanes, a knowledge that they used when depicting the deity. Her zemi idol was said to depict a woman, but the most common depiction of Guabancex presents a furious face with her arms extended in a "~" pattern.
Guabancex was also known as the "one whose fury destroys everything". From this we derive the Spanish word huracán and eventually the English word hurricane. As the pronunciation varied across indigenous groups, there were many alternative names along the way. The OED mentions furacan, furican, haurachan, herycano, hurachano, hurricano, and so on. The term makes an early appearance in William Shakespeare's King Lear (Act 3, Scene 2) and in Troilus and Cressida (Act 5, Scene 2), in which Shakespeare gives the following definition: "the dreadful spout Which shipmen do the hurricano call, Constringed (i.e., compressed) in mass by the almighty sun."
According to Taíno mythology, the semi of Guabancex was entrusted to the ruler of a mystical land, Aumatex. This granted him the title of "Cacique of the Wind", but it also imposed the responsibility of repeatedly appeasing the goddess throughout his long reign. Furthermore, due to the importance of the wind for travel between island and the need of good weather imperative for a successful crop, other caciques would offer her part of their food during the Chohoba ceremony. However, given Guabancex's volatile temper, these efforts often failed. When they did, she would leave his domain enraged and with the intent of bringing destruction to all in her path, unleashing the juracánes. She began by interrupting the balance established by Boinayel and Marohu, the deities of rain and drought. By rotating her arms in a spiral, Guabancex would pick the water of the ocean and land, placing it under the command of Coatrisquie who violently forced it back over the Taíno settlements destroying their bohios and crops. She would threaten the other deities in an attempt to have them join the chaos. She was always preceded by Guataubá, who heralded her eventual arrival with clouds, lightning and thunder. The easternmost of the Greater Antilles, Puerto Rico is often in the path of the North Atlantic tropical storms and hurricanes which tend to come ashore on the east coast. The Taíno believed that upon reaching the rainforest peak of El Yunque, the goddess and her cohorts would clash with their supreme deity, Yúcahu, who was believed to live there. Guabancex has an unspecified connection to Caorao, a deity that was also associated with storms and that was said to bring them forth by playing the cobo, a musical instrument made from a marine sea shell.
