A Severe Southwest Desert Thunderstorm: 19 August 1973
TLDR
A particularly severe and long-lasting thunderstorm occurred 19-20 August 1973 as mentioned in this paper, which was followed through its life cycle by means of radar, satellite, and surface observations, and was noteworthy for its very strong winds, locally heavy rain, and the magnitude of the pressure jump associated with it.Abstract:
Intense thunderstorms, which frequent the desert Southwest of the United States in the summer months, have been known by several different names: chubasco, haboob, and Sonora storm. Prior to the advent of satellites and radar, the sparsity of observations in the desert Southwest precluded any determination of where these storms developed, as well as information on their areal coverage and life cycle. A particularly severe and long-lasting thunderstorm occurred 19–20 August 1973. This storm was followed through its life cycle by means of radar, satellite, and surface observations. This particular storm was noteworthy for its very strong winds, locally heavy rain, and the magnitude of the pressure jump associated with it. The converging of two separate mesohighs is believed to be the cause of the very intense storm that moved westward across the Imperial Valley of Southern California.read more

TL;DR: In this article, an extreme, multiday rainfall event over southeastern Arizona during 27-31 July 2006 caused record flooding and a historically unprecedented number of slope failures and debris flows in the Santa Catalina Mountains north of Tucson.
