sea-storm of severest intensity, 1550s, a partially deformed adoption of Spanish huracan (Gonzalo Fernandez de Oviedo y Valdés, "Historia General y Natural de las Indias," 1547-9), furacan (in the works of Pedro Mártir De Anghiera, chaplain to the court of King Ferdinand and Queen Isabella and historian of Spanish explorations), from an Arawakan (West Indies) word. In Portuguese, it became furacão. For confusion of initial -f- and -h- in Spanish, see hacienda. The word is first in English in Richard Eden's "Decades of the New World":
These tempestes of the ayer (which the Grecians caule Tiphones ...) they caule furacanes.
OED records 39 different spellings, mostly from the late 16c., including forcane, herrycano, harrycain, hurlecane. The modern form became frequent from 1650 and was established after 1688. Shakespeare uses hurricano ("King Lear," "Troilus and Cressida"), but in reference to waterspouts.
Tiphon "violent storm, whirlwind, tornado," 1550s, from Greek typhon "whirlwind," personified as a giant, father of the winds, probably [Beekes] from or related to typhein "to smoke" (see typhus), but according to Watkins from PIE *dheub- "deep, hollow," via notion of "monster from the depths." The meaning "cyclone, violent hurricane of India or the China Seas" is first recorded 1588 in Thomas Hickock's translation of an account in Italian of a voyage to the East Indies by Caesar Frederick, a merchant of Venice:
concerning which Touffon ye are to vnderstand, that in the East Indies often times, there are not stormes as in other countreys; but euery 10. or 12. yeeres there are such tempests and stormes, that it is a thing incredible, but to those that haue seene it, neither do they know certainly what yeere they wil come. ["The voyage and trauell of M. Caesar Fredericke, Marchant of Venice, into the East India, and beyond the Indies"]
This sense of the word, in reference to titanic storms in the East Indies, first appears in Europe in Portuguese in the mid-16th century. It apparently is from tufan, a word in Arabic, Persian, and Hindi meaning "big cyclonic storm." Yule ["Hobson-Jobson," London, 1903] writes that "the probability is that Vasco [da Gama] and his followers got the tufao ... direct from the Arab pilots."
The Arabic word sometimes is said to be from Greek typhon, but other sources consider it purely Semitic, though the Greek word might have influenced the form of the word in English. Al-tufan occurs several times in the Koran for "a flood or storm" and also for Noah's Flood. Chinese (Cantonese) tai fung "a great wind" also might have influenced the form or sense of the word in English, and that term and the Indian one may have had some mutual influence; toofan still means "big storm" in India.
From the thighs downward he was nothing but coiled serpents, and his arms which, when he spread them out, reached a hundred leagues in either direction, had countless serpents' heads instead of hands. His brutish ass-head touched the stars, his vast wings darkened the sun, fire flashed from his eyes, and flaming rocks hurtled from his mouth. [Robert Graves, "Typhon," in "The Greek Myths"]
