Phoenix continues cleanup after major storm

Phoenix, and especially the zoo, are cleaning up after a massive storm that hit the city last week.

With flash flood warnings beginning early Monday night, the National Weather Service reported short of one inch of rain by early morning Tuesday, Sept. 1.

Social media boomed during the night as the monsoon progressed from thunder and lighting to rain and hail.

Cronkite News researched monsoons, El Nino and other extreme weather that impacts Phoenix.
