A second round of monsoon storms rolled through the East Valley late Thursday night bringing heavy rainfall, winds and blowing dust.
Very heavy rain fell across the East Valley on Aug 9/10, 2018. Peak 1-hr amounts of 3.6" were observed in Tempe. The chance of that happening at any location in the Phoenix area in a given year is less than 0.2%, making this event quite rare. #azwxpic.twitter.com/eRBtuGECuY
