Here is your word of the day, why not try and use the word in a piece of creative writing? link it to this post and let everyone take a look.
williwaw \WIL-ee-waw\, noun:
a violent squall that blows in near-polar latitudes, as in the Strait of Magellan, Alaska, and the Aleutian Islands.
Outside, a new note has crept into the wind, a black williwaw sound straight from the terrible wastes to the north.
— Walker Percy, The Moviegoer, 1961
