Jeff and Amber Wilson lost their lives in the flooding. As of Wednesday, July 9, their son, Shiloh, remains missing. According to a fundraising page set up by family, Jeff, Amber and Shiloh were in the Kerville area for a rodeo with Shiloh, who was described as a "young, spirited competitor." Jeff Wilson was a teacher in the Humble ISD.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.

A major flood event also struck the Texas Hill Country in July of 1987 after a series of 17 thunderstorms moved slowly, in succession, over the headwaters of the Guadalupe River in Kerr County. Anywhere from 5 to 10 inches of rain fell on the flood-prone areas, now deemed “Flash Flood Alley,” according to a National Weather Service report.
