Officials in flood-stricken central Texas on Wednesday again deflected mounting questions about whether they could have done more to warn people ahead of devastating flash flooding that killed at least 119 people on July 4.

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.
