Two tropical storms have led to deadly inland flooding in the United States already this season, underscoring how dangerous water can be.

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.

Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River rose rapidly.
