PHOENIX — Arizona’s drought is getting worse.

The latest drought update released Thursday by the United States Drought Monitor shows that a little more than 3 percent of the state is now experiencing an Exceptional Drought, which is the highest or worst level of drought.

The Exceptional Drought covers most of the Phoenix Metro Area.

The Extreme Drought area has also expanded to cover nearly 67 percent of the state.

By comparison, 58 percent of the state was experiencing Severe Drought conditions last week, and the majority of the state was drought-free in May.

Arizona isn’t the only spot where drought conditions have worsened. According to the U.S. Drought Monitor, drought conditions now cover 35.8 percent of the country, which is the largest drought coverage since October 2013.

The lack of monsoon rain is responsible for the expanding drought conditions across Arizona and the region.

Monsoon 2020 was the driest monsoon season on record for many spots in Arizona, including Flagstaff, the Grand Canyon, Show Low, Window Rock and Yuma.

Phoenix Sky Harbor only picked up an inch of rain which is well below the 2.71 season average, and most of that rain fell in a single night. With only two days of measurable rainfall in Phoenix, it will go down as the least active monsoon season on record.

Drought conditions will likely continue to worsen as our extended weather outlook shows that odds favor drier than average and warmer than average conditions for Arizona over the next few months.

The development of La Niña, which indicates cooler than average sea-surface temperatures along the equatorial Pacific Ocean could also affect how much winter rain and snow we see in Arizona.

Historically La Niña tends to bring drier than normal conditions across Arizona because the jet stream or storm track stays north of the region.
