Texas Gov. Greg Abbott visited the all-girls retreat Camp Mystic late Saturday as the death toll from Friday's flash flooding of the Guadalupe River continued to rise through the weekend.

When too much rain falls for the ground to absorb, it runs downhill, pulled by gravity into streams, creeks and rivers.

Rescue operations are ongoing in Central Texas after flash flooding along the Guadalupe River left 23 girls from Camp Mystic unaccounted for. Officials say dozens have died as catastrophic floods continue to ravage the Hill Country.
