Metro Phoenix had 2.81 inches of rainfall last month, the most in the month of July since rain indexing began in 1990 and much higher than the norm of .91 inches.
Some areas saw more, with a single storm in Scottsdale last month dropping about 3 inches.
Drivers are advised not to cross a flooded wash, even if it doesn’t look deep because a few inches of running water could still pose a serious risk.
The Arizona Department of Transportation also warns people to not drive around road-closed signs as it is not only a risk but violators could be cited under state law.
People are advised to reduce speed and maintain a safe distance between vehicles during storms, avoid sudden braking that can cause sliding on wet pavement as well as reducing speed by slowly taking your foot off the gas pedal and braking slowly.
