Viral posts promoted false claims that cloud seeding, a form of weather modification, played a role in the devastation. Meteorologists explain it doesn't work that way.

Sources have said FEMA wasn’t authorized to launch search and rescue teams until 72 hours after flooding began.

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

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

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.

There are reports some cloud seeding occurred a few days before the Texas flash flood.

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