Devastating flash floods in Central Texas on Friday have killed more than 100 people, including over two dozen at Camp Mystic, a Christian summer camp for girls along the Guadalupe River.  More than 160 people remain unaccounted for,

Experts say there was a number of factors that contributed to the tragedy including the extreme weather, the location of the holiday homes and timing. There was a large supply of moisture in the atmosphere from a tropical storm that had caused flooding in Mexico and then tracked north as it died out.
