Several organizations are accepting donations for those impacted by the floods, as well as first responders and volunteers.

At least 104 people, including more than two dozen children, died in the torrential downpour. Others remained unaccounted for.

Texas Hill Country, where much of the flooding took place this time, is often referred to as “flash flood alley.” It's home to steep terrain and a lack of vegetation that creates a perfect storm for waters to rise quickly.
