KERRVILLE, Texas -- Several hundred people gathered for a worship ceremony at a high school stadium in Texas on Wednesday evening to remember the at least 120 people who died in the catastrophic flash floods over the July Fourth holiday, as well the many still missing.

A flash flood is a rapid rise of water along a stream or in a low-lying urban area, the National Weather Service said. Flash flooding can result from slow-moving thunderstorms, from numerous thunderstorms that develop repeatedly over the same area, or from heavy rains associated with tropical cyclones.

Officials in Texas are facing mounting questions about whether they did enough to get people out of harm’s way before a flash flood swept down the Guadalupe River and killed more than 100 people, including at least 27 children and counselors at an all-girls Christian camp.

Young campers and a dad saving his family were among the dozens killed in the historic flash floods that tore through central Texas over the holiday weekend.

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.

Kerr County officials say they are still focused mainly on the search for survivors with hundreds still missing and weren't yet examining how the emergency response unfolded.

An 8-year-old girl who aspired to play the lead in an upcoming camp production is among the latest victims of the flooding in Texas.
