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.

Rescue operations are ongoing in Central Texas after flash flooding along the Guadalupe River left 23 to 25 girls from Camp Mystic unaccounted for. Officials say dozens have died as catastrophic floods continue to ravage the Hill Country.

Officials from Kerr County, Texas say the death toll has increased as efforts to locate the children from Camp Mystic continue.
