Occurrence and Distribution of Flash Floods in the Western Region

摘要

Of the eight states making up the Western Region, the two states reporting the greatest number of flash floods are Utah and Arizona. Nevada also has a high number of flash floods; however, they probably go unobserved because of the low population density. The purpose of this report is two-fold. First, it is to describe flash floods that have occurred in the Western Region as reported in the USGS Annual Flood Summaries from 1950-1969. At the same time, it is intended to provide the meteorologist and meteorological technician with a relatively geographical and seasonal distribution of flash flood events in the Western Region.
