In the early hours of Independence Day, rain pelted sleeping communities in central Texas. No one knew yet how devastating the storm would become.

A swift-moving flood that swept through the Hill Country of Texas on Friday, killing at least 79 people and leaving many more missing, was a flash flood.

Parts of the state devastated by flash floods that left at least 82 dead were braced for more heavy rains as forecasters extended flood warnings through Monday evening.

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 were 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.

The Guadalupe River set a new all-time high in Hunt, Texas, this weekend after deadly floods inundated the region.
