Kerr County failed to secure a warning system, even as local officials remained aware of the risks and as billions of dollars were available for similar projects.

Flooding has been at the top of Texans’ minds this week, but this is not the first time that the need for flood-related measures has come up among local officials.

The search for missing bodies is ongoing along Texas’ Guadalupe River after catastrophic and deadly flooding killed more than 100 people following a torrential downpour early Friday morning.

At a news conference on Sunday, Governor Greg Abbott said people in Texas were used to flash flood warnings, but there was no sense of how deadly this would be. "There's no expectation of a water wall of almost 30ft high," he added.

The Federal Emergency Management Agency failed to include multiple buildings on its flood risk map for Camp Mystic in Hunt, Texas, according to an analysis by NPR, PBS's FRONTLINE and data scientists.

The first weather emergency alert sent by the National Weather Service with urgent language instructing people to "seek higher ground now" was sent at 4:03 a.m. local time.
