As Central Texas reels from flash floods that killed over 100 people this weekend, questions are sharpening about whether officials could have done more to avert the tragedy – both in the decades leading up to the disaster,

The National Weather Service began sending flash flood warnings that should have triggered cellphone alerts a little after 1 a.m., while local officials began posting on Facebook about four hours later.

At Camp Mystic, a Christian summer camp in Hunt, Texas, where officials are grieving the loss of 27 children and counselors, belongings of the young campers are strewn about the flooded floors of a dormitory, while other items, including a pink backpack and a Camp Mystic t-shirt, were found along the bloated Guadalupe River, photos show.

Central Texas was ravaged by floods over the July 4th weekend leading to deaths, including children at Camp Mystic, an all-girls summer camp.

"Camp Mystic is grieving the loss of 27 campers and counselors following the catastrophic flooding on the Guadalupe River," the camp said in a statement.
