Arizona Drought Status(data through 7/19/11)
Data Source(s): U.S. Drought Monitor
Monsoon precipitation has been spotty across much of the Southwest during the past 30 days and has not helped alleviate drought conditions. Rather, dry conditions expanded and intensified across parts of Arizona, including the expansion of abnormally dry conditions along the Colorado River Valley and severe drought conditions across the northeast quarter of the state, according to the July 19 update of the U.S. Drought Monitor. More than 60 percent of Arizona is experiencing some level of drought, an increase from about 56 percent last month (Figures 4a–b). Drought impacts from southeast Arizona reported through Arizona DroughtWatch indicate the severity of the situation: very poor range conditions and lack of livestock water and forage.

The Arizona section of the U.S. Drought Monitor is released weekly (every Thursday) and represents data collected through the previous Tuesday. The maps are based on expert assessment of variables including (but not limited to) the Palmer Drought Severity Index, soil moisture, streamflow, precipitation, and measures of vegetation stress, as well as reports of drought impacts. It is a joint effort of several agencies.
