Short-term Drought Status Summary for July 2016

The map to the left updates every Thursday. The summary below reflects changes during the month of July.

Monsoon activity over northeastern Arizona has been quite spotty and has not made up the precipitation deficit from the disappointing El Niño winter. Therefore, moderate drought (D1) has expanded into northern Apache, northern and central Navajo and eastern Coconino counties.

In southeastern Arizona the monsoon has been quite active and locally heavy rainfall has been reported across parts of Cochise and Pima counties. This has led to an improvement from severe drought (D2) to moderate drought (D1) in Cochise County and northeastern Pima County, including Tucson.

While some areas of Santa Cruz County have received significant rainfall, the precipitation has been quite localized and many areas are still feeling the impacts from the dry winter, so there is no change to Santa Cruz County’s drought status at this time.

Prepared by the State Drought Monitoring Technical Committee, August 4, 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.
