Fort Lowell was a United States Army post active from 1873 to 1891 on the outskirts of Tucson, Arizona. Fort Lowell was the successor to Camp Lowell, an earlier Army installation. The Army chose a location just south of the confluence of the Tanque Verde and Pantano creeks, at the point where they form the Rillito River, due to the year-round supply of water during that period. The Hohokam natives had chosen the site centuries earlier, presumably for the same reason. To this day, shards of Hohokam pottery can still be found in the area. The Army claimed a military reservation that encompassed approximately eighty square miles and extended east toward the Rincon Mountains.
Tropical Storm Octave was considered the worst tropical cyclone in the history of Arizona, whose remnants caused devastating and record-breaking flooding in the state. The nineteenth tropical cyclone and fifteenth named storm of the 1983 Pacific hurricane season, the origins of Tropical Storm Octave were from a tropical disturbance that formed south of the Gulf of Tehuantepec on September 23, 1983. Steered by a deep layer high over Mexico, the disturbance moved west for four days before becoming a tropical depression on September 27 off the southwest coast of Mexico. Over an area of warm sea surface temperatures, it was able to quickly strengthen to peak winds of 50 mph (85 km/h), through wind shear prevented much further development. By September 30, Octave was accelerating to the northeast, steadily weakening due to cooler waters. That day it weakened to tropical depression status, and on October 2, Octave dissipated.
