A retrograding upper level low combined with anomalously high moisture levels led to showers and isolated thunderstorms producing heavy rainfall and numerous instances of considerable flash flooding across south-central Arizona on the 25th. The places that saw the heaviest rainfall amounts were areas that experienced heavy showers training over the same locations. Western portions of the Phoenix metro saw training showers with heavy rainfall occur, leading to widespread amounts of 1.5-2.5 with locally higher amounts of 3+. As a result, there were numerous reports of flash flooding, including multiple water rescues and numerous road closures due to flooding. Heavy rainfall also fell over multiple burn scars, leading to several instances of burn scar flash flooding. One of the burn scars that saw heavy rainfall was the Bush fire burn scar, which led to enhanced runoff and a rapid rise on Sycamore Creek. Several people were rescued after getting stuck in the increased flow in Sycamore Creek. No injuries were reported.
