Short-term Drought Status Summary for September 2017

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

The monsoon activity ended early this season leaving much of southeastern, eastern, and central Arizona abnormally dry (D0).

Thunderstorm activity was highly localized with some areas receiving ample rainfall, but the majority of precipitation accumulated from middle of July to the beginning of August. Below average precipitation through the latter half of August and all of September combined with warm temperatures contributed to the dryness for the end of summer.

While a low-pressure system could bring isolated showers to the southeast part of the state in early October, rainfall totals are not likely to be significant. Drought conditions are not anticipated to show improvement with the climate outlook for the next three months showing a high probability for warmer than normal temperatures.

Prepared by the State Drought Monitoring Technical Committee, October 6, 2017.


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, 2017. The next update in early November will reflect the conditions of July, August and September.

Long-term Drought Status Update: April - June 2017

The long-term map shows that drought conditions deteriorated on the little Colorado River watershed from no drought to abnormally dry (D0) and on the San Pedro watershed from abnormally dry to moderate drought (D1). This is largely due to the continuous dry conditions in these areas since last year’s monsoon.

It’s likely that the San Pedro and some of the other neighboring watersheds may improve after this monsoon season as this is usually the wet time of year for the southern watersheds.
