Arizona Drought Status(data through 6/18/13)
Data Source(s): U.S. Drought Monitor
Drought continues to be widespread and intense in the Southwest. Moderate drought, at the least, covers about 92 percent of Arizona and severe or extreme levels cover more than 70 percent of the state (Figures 4a–b). The area exposed to extreme drought increased by about 3 percent in the last month.
In the past 30 days, dry conditions and above-average temperatures caused drought conditions to slightly intensify in the northeastern corner of the state and around the Mogollon Rim. The largest changes in drought status occurred around the Mogollon Rim, which was drought-free just two months ago after above-average precipitation fell across the region in the winter. Sharp deficits in precipitation and warm temperatures have driven the return of moderate drought across the area. The Vegetation Drought Response Index (VegDRI) shows pre- to moderate drought conditions across central Arizona and much of eastern Arizona, reflecting the worsening conditions.Notes:
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.
