This is false. It is not possible that cloud seeding generated the floods, according to experts, as the process can only produce limited precipitation using clouds that already exist.

Here's what to know about the deadly flooding, the colossal weather system that drove it and ongoing efforts to identify victims.

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.

Factors such as elevation and soil consistency are vastly different in Florida than in Texas, according to meteorologists.

Central Texas is infamous for its flash flooding and arid soil, hard-packed ground into which water does not easily infiltrate. So when rain hits the ground, it runs off the region's hilly terrain and canyons and accumulates into creeks and rivers rapidly, overwhelming them, causing them to rise quickly.

"A lot of the weather forecast offices now are not operating at full complement of staff," said the former lead of NOAA.

First reported by the Houston Chronicle, cloud seeding involves releasing silver iodide into clouds to increase rainfall under specific conditions. According to the Texas Department of Licensing and Regulation, it is used in select areas of West and South Texas, typically during dry seasons to enhance precipitation.
