A storm system moving across the west coast in combination with well above normal moisture levels for mid March standards with values above the 99th percentile resulted in waves of light to moderate rainfall activity across the region. The heaviest rainfall was observed across the areas to the north and east of Phoenix, where multiple inches of rain were observed. Given that the flows along rivers, small streams, creeks, and washes were elevated due to previous precipitation activity from previous storms and with the additional rainfall that fell, the water levels rose above alarm stage, resulting in flooding along low-water crossings.
