The official tally of storm-related deaths across Texas rose to 131 on Monday as authorities warned of yet another round of heavy rains 10 days after a Hill Country flash flood that transformed the Guadalupe River into a killer torrent.

More than a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

Search operations continued overnight in Kerr County, which was hit the hardest, with at least 106 deaths, including 36 children, according to officials. A flood watch remains in effect through at least Monday evening for the Texas Hill Country,

Over 130 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

A flood watch is in effect into July 15 for more than a dozen counties as saturated ground gets drenched again.
