The danger has extended to Travis, Williamson and Burnet counties, where very dangerous flash flooding is ongoing Saturday morning. Between 5 and 12 inches of rainfall has fallen there, the weather service said, calling it a "Particularly Dangerous Situation with life-threatening flash flooding."

At least 24 people are dead after heavy rain lashed Texas, leading to "catastrophic" flooding. Texas Gov. Greg Abbott said emergency responders remained in a search and rescue posture, hours after the flooding along the Guadalupe River inundated nearby areas.

Multiple deaths have been reported in Texas after heavy rain caused flash flooding of a river, while search teams used boats to conduct rescues Friday as fast-moving water threatened riverfront communities near wildlife habitats and campgrounds.
