KERRVILLE, Texas — Shock has turned into grief across Texas where at least 120 people died from flash floods and more were missing as the search for victims moved methodically along endless miles of rivers and rubble Thursday.

Sisters Blair Harber, 13, and Brooke Harber, 11, were killed, along with their grandparents, when surging floodwaters ripped through the community. Their parents were staying in a different home at Casa Bonita and survived, according to the family's GoFundMe.

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

Over the last decade, an array of local and state agencies have missed opportunities to fund a flood warning system intended to avert the type of disaster that swept away dozens of youth campers and others in Kerr County,

Viral posts promoted false claims that cloud seeding, a form of weather modification, played a role in the devastation. Meteorologists explain it doesn't work that way.

At least 27 campers and counselors at Camp Mystic perished in Friday's floods, with the total death toll in the floods now surpassing 100.

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.

Renee Smajstrla, a 8-year-old straight-A student from Ingram, Texas, who had played a role in her school’s production of “The Wizard of Oz,” was one of the victims who died in the flash floods at Camp Mystic, her family said.
