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

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.

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

In the early morning hours of July 4, torrential rains triggered flash flooding in central Texas. At least 130 people were killed, including dozens of children who were at summer camps along the Guadalupe River.

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