While life in the Sonoran Desert struggles for months without rain, almost right on cue every July monsoon winds change and bring moisture from the Gulfs of California and Mexico. Occastionally storms will form off the Mogollon Rim and move southwesterly towards the lower deserts, bringing fiece winds and heavy rain. This beautiful storm raged towards me and I stayed up until the final safe moments to capture a beautiful shelf cloud form in front of me while the rainshaft was lit up by the setting sun.
