Thursday, July 3
The National Weather Service issued several flood watches for counties in central Texas on Thursday, July 3, warning of the possibility of rain and flash flooding through Friday, but these were not emergency alerts.
11:41 p.m., Bandera County —?NWS sends a warning about potentially "life threatening" flash flooding of creeks and streams for residents of central Bandera County, the neighboring county to the south of Kerr County and Camp Mystic. The message includes some standard NWS flash flooding language: "Turn around, don't drown when encountering flooded roads. Most flood deaths occur in vehicles. Be especially cautious at night when it is harder to recognize the dangers of flooding. In hilly terrain there are hundreds of low water crossings which are potentially dangerous in heavy rain. Do not attempt to cross flooded roads. Find an alternate route."?
