Arizona Drought Status(data through 3/19/13)
Data Source(s): U.S. Drought Monitor
Several cold winter storms that produced widespread rain and snow passed through Arizona during the past 30 days, helping erase abnormally dry conditions present in the Mogollon Rim. In this area, winter storms helped push winter season precipitation totals close to average. However, precipitation across the rest of the state was below average.
The March 19 update of the U.S. Drought Monitor shows a state mostly characterized by drought conditions, with about 30 percent of the state classified with severe or extreme drought and nearly 80 percent classified with some drought category (Figures 4a–b). These conditions are expected to persist in coming months as the region transitions into the historical dry spring. However, because the upcoming period is historically dry, it will also be difficult for precipitation deficits to substantially increase. On the other hand, it will also be difficult for drought conditions to improve unless atypical spring storms waft over the region.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.
