The heavy rain that turned a river in Texas into a raging wall of water was fueled by unique atmospheric conditions, according to meteorologists and climate scientists.

The search for missing bodies is ongoing along Texas’ Guadalupe River after catastrophic and deadly flooding killed at least 89 people following a torrential downpour early Friday morning.

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.
