parental rainfall, Douse Kerr County, Texas, Friday morning, causing flooding from the Guadalupe River.

The death toll has now risen to 24 people and one death was also reported in Kendall County.

Rescue teams have been working through the night to find survivors as more than 20 people remain unaccounted for from a summer camp in Hunt, Texas.

NBC's Ryan Chandler is on the ground with more.

In central Texas, a catastrophic flood emergency.

It's going to be a mass casualty event.

Authorities saying 14 helicopters are in the air.

One rescuer dangling from a chopperper appearing to help someone up in a tree as flooding rages below cars lifting off the ground swept away by the powerful waters these steps leading to a house that's no longer there this is our house house right. Another pushed down the road.

The water started to rise very rapidly.

I mean, wrap up.

Along the river, a series of summer camps.

The Lahunta camp for boys posting that everyone is safe. But some girls at Camp Mystic trapped.

Now there are 20-some that aren't accounted for. We're praying for all of those

missing to be found alive. You can feel the anxiety here as parents are waiting to hear

word about their child. We're told that these children are being transported by helicopter,

the only way out of the camp as parents parents wait to hear, they've returned safely.

The county judge pressed on why the camps weren't evacuated. We knew there were those who'd be a problem.

Why weren't these camps evacuated? I can't answer that. I don't know. These camps were in arms way.

We knew that this flood was coming. We didn't know this flood was coming.

Rest assured, no one knew this kind of flood was coming.

The tight-knit Texas towns across Kerr County are popular recreation areas.

Len Clendenin and Rory Higgins were camping, asleep in their cabin when the water started rushing in.
