Derecho (pronounced as /dəˈreɪtʃoʊ/ , “day-ray-cho”) is a loanword
from Spanish, in which it means “straight”. It refers to a fast-moving
storm with a straight or slightly bowed wavefront that travels long
distances across country, the linear equivalent of a rotating tornado.
The term was first used in 1888 by Professor Gustavus Hinrichs of the
University of Ohio in a paper titled ''Tornados and Derechos''.
