Monthly Drought Status Summary: September 2020
A combination of less than 50% of average precipitation and record setting high temperatures across Arizona resulted in a significant expansion of short-term drought conditions.
Some rainfall was received along the southern border, particularly in Cochise and Santa Cruz counties. However, total rainfall was generally less than an inch across the state with Phoenix, Flagstaff, and Tucson all reporting zero inches.
The entire state is in Moderate (D1) or worse drought. Currently, 67% of the state is in Extreme Drought (D3), compared to 42% at the beginning of September, and 3% is in Exceptional Drought (D4) compared to 0% last month.
The monsoon season ended with the hottest and driest summer since 1896. After starting off with a relatively wet winter, Water Year 2020 ended with unfavorable conditions.
At the end of each month, the MTC produces the web-based, short-term drought status update based on U.S. Drought Monitor's maps for the past four weeks. An email with the latest map and summary is sent to interested parties.
