The Tom Green Sheriffs Office reported flooded roads in Arden.

Wider weather episode

The combination of abundant tropical moisture and a weak upper level disturbance produced a complex of slow moving thunderstorms across the Concho Valley. As a result, very heavy rain fell in a short period of time on the morning of August 17 and produced flash flooding in San Angelo and Mertzon. Also, radar rainfall estimates were 9 to 10 inches in northwest Tom Green County, just west of OC Fisher Reservoir.
