Flash floods happen when heavy rains unleash more water than the ground can absorb, causing that water to pile up and flow to low-lying areas

Growing up near the Guadalupe River in Kerrville, Texas, could sometimes feel like living near a volcano. I was born two blocks away from the gorgeous river that flows from the Hill Country to the Gulf of Mexico, just one year before the devastating and deadly 1987 flash flood, often described around town as the “big one.”
