Very heavy rainfall has resulted in three to six inches of rain over much of Travis into northern Hays counties since 5 PM. Additional heavy rain continues to develop and fall over those counties. This includes the City of Austin. Dozens (if not hundreds) of low water crossings are impassable. As nightfall approaches and high water becomes more difficult to see this flash flood event will only become that much more dangerous. This is a dangerous situation with the potential for significant flash flooding, including locations that may not typically flood with a ‘heavy rain’. Please avoid driving this evening if at all possible in Travis County – including Austin. Numerous water rescues are already underway due to folks driving into high water. We’ve heard of at least one vehicle swept away. The LCRA has begun flood operations at the Tom Miller Dam due to rapidly rising water levels on Lake Austin. Even after the rains stop it will take several hours for the water to recede.
