A year has passed since the devastating Hill Country floods, and Texas is taking steps to improve its flood warning system. New flood-warning sirens are being installed in areas that were severely affected by the floods. Major gaps still exist in the warning system, however, leaving some communities without any warning system in place.

This issue was uncovered by a CBS Texas I-Team investigation. For more information on the current state of Texas' flood warning system and the investigation's findings, readers can refer to the CBS Texas report.
