When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

Flash floods in Texas have killed at least 107 people over the Fourth of July weekend, with more than 160 still missing.

More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

There are reports some cloud seeding occurred a few days before the Texas flash flood. But it’s important to understand that cloud seeding has a relatively short-term effect in that a certain cloud is seeded and perhaps turns into one individual rain cloud or even a thunderstorm. The increased rainfall would not last for days.

The heavy rain that turned a river in Texas into a raging wall of water was fueled by unique atmospheric conditions, according to meteorologists and climate scientists.
