The storm came after forecasters warned Austin could see damaging wind, hail, lightning and heavy rain as storms moved toward the Interstate 35 corridor late Tuesday. The National Weather Service had Travis County under a flood watch through Wednesday morning, with recent rain making the area more vulnerable to quick runoff and street flooding. The outages that did happen were mostly at the circuit level, meaning crews were often able to check the equipment and restore power quickly. Mitchell said some customers were back online within about 15 minutes, and most were restored within 30 minutes.
