According to the Harris County Flood Control District, strong storms dumped between four to six inches of rain in some areas.
Some of the spots to see the most rainfall were reported in west Houston near the Brays Bayou, and eastern Harris County near Cedar Bayou.
In southwest Houston, several cars were submerged in water at Bellfort and the Southwest Freeway.
ABC13 crews also spotted good Samaritans helping strangers who got stuck in high water. In the video, people in a white truck helped pull a stalled car out of high water on I-45 and W Mount Houston.
On Memorial Drive and Houston Avenue, rescue crews searched two submerged vehicles at an underpass. Officers were spotted climbing on the hood of one of the vehicles, and looking inside. Officers eventually gave the all-clear that no one was inside.
Manholes were also spotted bubbling and flooding in downtown Houston at Milam and Commerce. At one point, crews shut down part of the street due to high water.
