derecho
n.— «The third form appears rather as horizontal than as vertical whirls. They appear to be what Dr. Hinrichs has called derechoes (from derecho, straight) and advance in the form of a horizontal roll of dust. The front extends in length as they advance, so that the territory they pass over is fan-shaped, instead of the strap-shaped area of the tornado proper.» —“Tornadoes: What They Are; Where and When They Occur” by Mark W. Harrington Los Angeles Times Apr. 16, 1893. (source: Double-Tongued Dictionary)
