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.

Twice, the Texas Division of Emergency Management turned down Kerr County's requests for money to improve flood warnings.

Emergency officials are starting to focus on alert systems as they search for answers about how the flash flooding swept away so many.

Mourners gathered Wednesday night at Tivy High School's stadium, where they had celebrated victories and suffered losses on the field, said Ricky Pruitt, of the Kerrville Church of Christ. “Tonight is very different than all of those nights,” he said. Among those who died was the school's soccer coach.

State and local officials in Texas have come under scrutiny over the lack of sirens in place to warn people of impending flash flooding.

When deadly floods swept through Texas, the National Weather Service issued a series of warnings that should have automatically triggered alerts to be sent to cellphones as the Guadalupe River began to rise.

Over 100 people have died in the Texas flooding as of Tuesday. Here are answers to commonly asked questions from USA TODAY readers.
