Unfounded rumors linking an extreme weather event to human attempts at weather modification are again spreading on social media. It is not plausible that available weather modification techniques caused or influenced the July 4 flash flooding along the Guadalupe River in Texas.

The official tally of storm-related deaths across Texas rose to 131 on Monday as authorities warned of yet another round of heavy rains 10 days after a Hill Country flash flood that transformed the Guadalupe River into a killer torrent.

For the first time since the deadly July Fourth flooding in the Texas Hill Country, Kerr County has no flood advisories or rain in the forecast, allowing search crews to continue their work looking for the bodies of more than 150 missing people.

The State Flood Plan, published last year, identified $54 billion in flood mitigation, warning and data needs. The state has awarded around $660 million since the plan was published, with a special legislative session coming soon.

National Weather Service Meteorologist Kate Abshire says Flash Flood Alley contains several flooding characteristics to create the perfect storm.

As ominous storm clouds gather once more over Texas, the desperate search for more than 150 individuals still missing since the catastrophic July 4 floods has now stretched into its second week.
