Weekly Map - Drought Conditions

The Arizona Drought Monitoring Technical Committee confers weekly to advise the U.S. Drought Monitor authors on the current drought conditions in Arizona, and makes recommendations about the position of the drought boundaries for Arizona. The U.S. Drought Monitor is the official record of drought for Federal drought relief claims. Information used by the MTC in advising the Drought Monitor authors includes numerous drought indices, precipitation and stream flow data, and impacts data. Every Thursday, the Drought Status web page automatically updates with the latest U.S. Drought Monitor map of Arizona.

Short-term Drought Conditions

Monthly Drought Status Summary: June 2024

June Short term

June 2024 tied with 2021 as the hottest statewide June on record. Several cities also recorded their hottest June, as did La Paz, Coconino, Navajo, Apache, Pinal, and Graham counties. While June is climatologically the driest month of the year, monsoon activity started early for the season, reaching the 16th wettest June on record for the state. 

Short-term drought slightly improved in June, decreasing Severe (D2) short-term drought in Cochise County (2% of state). Moderate (D1) short-term drought also slightly improved (16% of state), remaining in eastern Mohave and western Coconino counties, central Maricopa County and a small portion of southern Yavapai County, eastern Gila County, and areas along southeastern counties, including Apache, Graham, Greenlee, and Cochise counties. The remainder of the state (82%) was Abnormally Dry (D0) or fully without drought.

There is a 70% chance of La Nina developing by late summer/early autumn, then persisting through the winter. Given most La Nina episodes are drier than normal for the Southwest, there is at least a 40% chance upcoming autumn and winter precipitation falls below normal.

This report was prepared by the Arizona Drought Monitoring Technical Committee on July 16, 2024. Arizona's short-term drought status map is updated during the first week of each month.

Arizona's long-term drought status map is updated quarterly and the next update will take place in early June, it will reflect the conditions of  April, May, and June. The long-term drought status for each watershed is determined by comparing the precipitation and streamflow percentiles for the past 24, 36, 48 and 60 months to a 40-year historical record.
