Short-term Drought Status Summary for September 2016

The larger map updates every Thursday. The summary below reflects changes during the month of September.

The monsoon activity occurred primarily in the northwest and southeast quarters of the state. Most of Cochise, Graham and Greenlee counties have improved to no drought, along with western Coconino and eastern Mohave counties.

Central Arizona, along with most of La Paz, Navajo, and Apache counties remain in moderate drought (D1), as the monsoon failed to deliver significant rainfall to these areas. Most of Yuma County is in severe drought (D2). The dry conditions from the failed El Niño have not been alleviated by the monsoon across the northeast and southwest. There is no clear signal for the winter precipitation outlook. Long-term conditions remain abnormally dry (D0) across most of the state.

Prepared by the State Drought Monitoring Technical Committee, October 11, 2016.


Arizona’s long-term drought status map is updated quarterly. The long-term drought status for each watershed is determined by comparing the precipitation and streamflow percentiles for the past 24, 36 and 48 months to a 40 year historical record 

This report was prepared by the Arizona Drought Monitoring Technical Committee, August 4, 2016. The next update in early November will reflect the conditions of July, August and September.

Long-term Drought Status Update: April - June 2016

There are no changes to the long-term drought status in Arizona. Winter was drier than normal in much of the state, particularly in southern Arizona, causing several watersheds to move into the abnormally dry category.

Spring produced local pockets of wetter than normal conditions, however snow pack over higher terrain ended the season on a poor note. Long term drought status focuses on state water resources and precipitation during the first half of the calendar year proved insufficient to allow for long term drought improvement.

The monsoon has been quite localized so far, having little impact on reservoirs or aquifers, and its effects on the long-term drought will be evaluated after September.
