"There has been a lot of misinformation flying around lately, so let me clarify: the Texas Department of Agriculture has absolutely no connection to cloud seeding or any form of weather modification," Miller said in a statement.
The Gulf, which borders Texas, has become significantly warmer in recent years due to climate change, Swain explained. This results in a very warm body of water that produces a lot of evaporation, releasing more tropical moisture into the air than seen historically.
As a succession of thunderstorms fed by the remnants of Tropical Storm Barry pummeled Texas' Hill Country, tools used by the National Oceanic and Atmospheric Administration to detect extreme rainfall began “maxing out the color charts.
Texas Hill Country is no stranger to extreme flooding. In the rugged, rolling terrain it’s known for, heavy rains collect quickly in its shallow streams and rivers that can burst into torrents like the deadly flood wave that swept along the Guadalupe River on July 4.
There was little indication of how torrential the Texas downpours would become before dawn. At least 27 people were killed, many of them children at Camp Mystic.

"These are roughly one-in-1,000-year events, [and] would be extremely rare in the absence of human-caused warming,” one climate scientist says.
Radar data can estimate rainfall to a fairly accurate amount. The rain data in the case of the deadly tragedy that unfolded in the Texas Hill Country last weekend shows exactly why the area around Camp Mystic and the Guadalupe River, outside of San Antonio, had such a raging flash flood.
Some regions in the mid-Atlantic are also facing risks of flooding. On Sunday, Tropical Storm Chantal flooded parts of North Carolina, where more than 10 inches of rain fell near the Chapel Hill area. The Haw River, near Bynum, North Carolina, crested to nearly 22 feet, the highest crest on record there, as a result of those heavy rains.
Meanwhile, anguished parents waited for word on the 10 young campers still missing from Camp Mystic, which was hit hard by floodwaters.
