Flash floods in Texas killed more than 100 people over the Fourth of July holiday weekend and left others still missing, including girls attending a summer camp.

The devastation along the Guadalupe River, outside of San Antonio, has drawn a massive search effort as officials face questions over their preparedness and the speed of their initial actions.

Here's what to know about the deadly flooding, the colossal weather system that drove it in and around Kerr County and ongoing efforts to identify victims.

Massive Rain Hit At Just The Wrong Time, In A Flood-Prone Place

The floods grew to their worst at the midpoint of a long holiday weekend when many people were asleep.

The Texas Hill Country in the central part of the state is naturally prone to flash flooding due to the dry dirt-packed areas where the soil lets rain skid along the surface of the landscape instead of soaking it up. Friday's flash floods started with a particularly bad storm that dropped most of its 12 inches (30 centimeters) of rain in the dark early morning hours.

After a flood watch notice midday Thursday, the National Weather Service office issued an urgent warning around 4 a.m. that raised the potential of catastrophic damage and a severe threat to human life.
