Episode narrativeepisode_narrativeA vigorous upper level low pressure system and associated cold front combined to produce strong thunderstorms with locally heavy rain over south central Arizona during the afternoon and evening hours on September 27th. During the early afternoon, a severe squall line moved east across south central Arizona, bringing damaging winds. Shortly thereafter, heavy rains developed which initially led to both urban flooding and flash flooding; as the afternoon progressed more significant areal flooding developed over the central deserts which prompted the issuance of multiple Areal Flood Warnings. Numerous Flash Flood Warnings and Urban and Small Stream Flood Advisories were issued for south central Arizona with this heavy rainfall event. No injuries were reported due to the flooding.
Event narrativeevent_narrativeStrong thunderstorms moved across the eastern portion of the greater Phoenix metropolitan area during the afternoon and evening hours on September 27th, and they produced locally heavy rain with peak rain rates in excess of 2 inches per hour. The heavy rains affected the community of San Tan Valley and led to significant stream and street flooding in the area. According to a trained weather spotter located about 2 miles southeast of San Tan Mountain, 1.05 inches of rain was measured in 30 minutes, beginning at about 1600MST. Washes in the area were reported to be running about 4 inches deep. Another trained weather spotter located 1 mile north of San Tan Valley measured 1 inch of rain in 30 minutes beginning at 1610MST, and the rain led to street flooding with water near the top of the curbs. The flooding resulted in the issuance of both Small Stream Flood Advisories and Flash Flood Warnings for the area.
