Episode narrativeepisode_narrativeThunderstorms continued to develop across the south central Arizona deserts during the evening hours on August 21st, affecting both the greater Phoenix area as well as portions of northwest Pinal county including the community of Coolidge. Due to the very moist and unstable nature of the atmosphere, the thunderstorms primarily generated very heavy rainfall with rain rates well in excess of 2 inches per hour. The heavy rain was sufficient to cause some urban street flooding. Additionally, a few storms were able to produce gusty and damaging microburst winds which were strong enough to blow down power poles.
Event narrativeevent_narrativeScattered thunderstorms developed across northwest Pinal county during the evening hours on August 21st, and they affected communities such as Coolidge, San Tan Valley and Arizola. Due to the very humid and unstable nature of the atmosphere, the storms were able to produce very heavy rainfall with rain rates well in excess of 2 inches per hour. At 720 pm, a trained weather spotter 1 mile west of Coolidge reported that he had measured 2.54 inches of rain, and street flooding was occurring in the area. At 815 pm, another trained weather spotter near Coolidge measured 2.07 inches of rainfall, much of which had fallen since 7 pm. The heavy rain led to the issuance of a Flash Flood Warning for the Coolidge area beginning at 7 pm and continuing through 830 pm. Heavy rain continued to fall into the mid evening; at 9 pm another trained weather spotter 2 miles north of Arizola measured nearly one inch of rain in a thunderstorm and nearly one half inch had fallen in the last 25 minutes.
