Arizona Drought Status(data through 7/17/12)
Data Source(s): U.S. Drought Monitor
Drought conditions have changed little over the past 30 days, but early monsoon precipitation likely will provide some short-term relief in some parts of the state (Figure 4a). Any changes likely will be reflected in subsequent U.S. Drought Monitor updates. Early season monsoon precipitation has been heaviest across far southern Pima and Santa Cruz counties and parts of Yavapai and southern Mohave counties; much of the state has received some monsoon moisture. Nevertheless, all of Arizona is experiencing some level of drought, with more than 94 percent of the state classified with at least severe drought (Figure 4b). The only change in drought status in the last month was the development of a small area of extreme drought in far southern Pima County.
In drought-related news, all of Arizona is recognized as a federally declared drought disaster area for the 10th year in the last 13 (Arizona Daily Star, July 14). This declaration, issued by the U.S. Department of Agriculture, makes available low interest loans for farmers and ranchers to mitigate crop damage and losses and aid the purchase of emergency feed for livestock. Last year, which also was declared a federal drought disaster, 4,200 ranchers used $8.7 million in livestock forage assistance.
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.
