Episode narrativeepisode_narrativePlentiful tropical moisture spread into central Arizona ahead of a tropical depression named 16-E, creating a very moist and unstable atmosphere. As a low pressure system moved eastward across Arizona on September 22nd, scattered thunderstorms developed and some of the stronger storms generated intense rainfall which produced episodes of both urban flooding and flash flooding in the greater Phoenix area during the evening hours. Some of the more significant flooding affected communities such as Scottsdale, Mesa and Apache Junction. Urban Flood Advisories and Flash Flood Warnings were issued for portions of the greater Phoenix area as a result of the flooding. Fortunately, no injuries were reported.
Event narrativeevent_narrativeSignificant tropical moisture was present across the greater Phoenix area on September 22nd; the moisture spread into the area ahead of tropical depression 16-E which passed by Arizona to the southeast. A passing low pressure system acted on the moisture and scattered thunderstorms resulted, some of which affected Scottsdale. Due to the high moisture content, some of the storms produced very heavy rainfall with peak rain rates greater than 1 inch per hour. The heavy rain resulted in episodes of urban street flooding and led to the issuance of an Urban and Small Stream Flood Advisory for Scottsdale at 1800MST. According to a trained spotter 5 miles southwest of central Scottsdale, the street flooding caused water to rise above curb level on Hayden Road throughout Scottsdale Muni Airport, and along Thunderbird Road between Hayden Road and 64th Street. Street flooding was also present along Sweetwater from 60th Street to 64th Street. In some locations, traffic was barely able to pass through the deepest locations where the water is flowing. The flooding as reported by the spotter occurred around 1800MST.
