Radar data can estimate rainfall to a fairly accurate amount. The rain data in the case of the deadly tragedy that unfolded in the Texas Hill Country last weekend shows exactly why the area around Camp Mystic and the Guadalupe River, outside of San Antonio, had such a raging flash flood.

Over 100 people are dead after heavy rain led to devastating flooding in Texas. Kerr County was hit the hardest, with at least 84 deaths, including 28 children. President Donald Trump signed a disaster declaration for the county and the Federal Emergency Management Agency is on the ground there.
