A stretch of chain-link fence along the Guadalupe River in the Texas town of Kerrville has become a focal point for the community's grief.

This part of Texas Hill Country is known for flash floods. Why were so many people caught off guard when the river turned violent?

In the heart of Kerrville, hundreds gathered Thursday evening for a community vigil honoring the victims of the catastrophic Hill Country flooding — a disaster that has already claimed at least 103 lives in Kerr County, with more than 100 still missing.

President Donald Trump is visiting Texas on Friday to assess catastrophic flooding that has killed at least 120 people.

At least 119 people have been found dead in nearly a week since heavy rainfall overwhelmed the river and flowed through homes and youth camps in the early morning hours of July 4. Ninety-five of those killed were in the hardest-hit county in central Texas, Kerr County, where the toll includes at least three dozen children.

More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

Two of the state's best-known brands, both born in Kerrville, are showing their support for Hill Country flood victims in a big way. Grocery giant H-E-B started as a tiny family-owned store in Kerrville in 1905. H-E-B, a household name to most Texans and headquartered in San Antonio, now has 435 stores in Texas and Mexico.

Jonathan McComb was the sole family member to survive a Texas flooding in 2015. Now, he's in Kerrville searching for victims in from the latest flooding.
