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_narrativeA line of powerful thunderstorms moved east across the greater Phoenix area during the early afternoon hours, followed by additional thunderstorm development which continued into the evening on September 27th. The stronger thunderstorms produced heavy rain with peak rain rates in excess of 2 inches per hour. The rain led to significant and widespread urban street flooding across the greater Phoenix metropolitan area, resulting in the issuance of both Urban and Small Stream Flood Advisories and Flash Flood Warnings. According to a trained weather spotter in Tempe, a storm total rainfall amount of 2.14 inches was measured as of 1720MST. Another trained spotter 2 miles west of Fountain Hills measured the exact same amount in a 3 hour period ending at 1728MST. At 1440MST, a trained spotter 2 miles southeast of Glendale reported flooded roadways with water covering the wheel wells of vehicles. At 1517MST, a trained spotter 4 miles south of Goldfield Ranch reported flooded roads, with some roads impassable. At 1625MST a trained spotter 3 miles northwest of Phoenix Sky Harbor Airport reported that the intersection of 24th Street and Thomas Road was flooded and impassable.
