KERRVILLE, Texas — Shock has turned into grief across Texas where at least 120 people died from flash floods and more were missing as the search for victims moved methodically along endless miles of rivers and rubble Thursday.

More than 111 people have died across six counties after flash flooding from heavy rain began affecting the state last week.

Officials at the Comfort Volunteer Fire Department triggered a flood warning siren last week when the Guadalupe River began to swell.

Viral posts promoted false claims that cloud seeding, a form of weather modification, played a role in the devastation. Meteorologists explain it doesn't work that way.

Q: Is it true that if President Donald Trump hadn’t defunded the National Weather Service, the death toll in the Texas flooding would have been far lower or nonexistent? A: The Trump administration did not defund the NWS but did reduce the staff by 600 people.

A retired nurse, her son and a family friend say they were lucky to survive last week's flash floods in Texas that killed more than 100 people, including many summer campers.

When the precipitation intensified in the early morning hours Friday, many people failed to receive or respond to flood warnings at riverside campsites known to be in the floodplain.
