Summers in Arizona mean heat, triple-digit temperatures, and desperately trying to stay cool. But summers in Arizona also mean monsoons - big, bright thunderstorms returning rain to the desert. During the summer monsoon season, Phoenix receives one-third of its annual rainfall, a necessary relief to help combat the drought that 83% of the state is experiencing, according to the National Weather Service. While monsoons bring reprieve from the extreme heat and aid in the drought, they are sometimes responsible for power outages and extreme flooding.  Flooding in urban areas, such as Phoenix, often causes minor headaches such as traffic congestion on surface streets and highways. However, in parts of the state outside the Valley, floods can be dangerous, and occasionally deadly. In this week's episode of Valley 101, a podcast from The Arizona Republic and azcentral.com, we share the good and the bad of monsoon season in Arizona.Learn more about your ad choices.
