Victor Oh, kendo is in Putnam County, Tennessee, with much more on all this.

Good morning, Victor.

Good morning, Robin.

They took the brunt of that E F four right here.

Homes were blown away, shredded, reduced to piles of debris and rubble off the 25 people who died across Middle Tennessee.

18 of them were right here in Putnam County, and as you take a look from above, you'll understand why this neighborhood was decimated.

360 degree devastation.

There is nothing left, and there are still people missing.

This morning, an urgent search for the missing after at least two devastating tornadoes in Tennessee claimed the lives of at least 25 people thes exclusive new thermal images from a drone police are using to help find those who might still be trapped in the rubble.

I've done a lot of lot of these since Hurricane Katrina, hurricanes and tornadoes.

This is probably one of the worst tornado scenes I've seen grand phone.

Youngest, My son in law.

I'm so sorry.

Both my nephews lost their parents.

One.

That storm killed them both Lamar Redman losing his sister and brother in law, Cathy and Keith Selby.

This is the front porch, and beyond that port was the home itself.

It's gone.

It's completely gone.

The youngest victim, just two years old, Sawyer Kimberlin, died along with his parents, Josh and Aaron.

But amid the tragedy, harrowing stories of survival.

If we hadn't woken up her be gone.

You know, there's no way we'd even be here.

I want my wife up, and we just took off.

Running down to the basement, 73 year old Jean Gregory's husband, Frank, using himself as a human shield to protect her.

So he came in and juggling off to bed around the floor got tough way.

That couple somehow lucky enough to walk away without a scratch.

Search crews will be out again later this morning, the way one neighbor put it, life as they knew it Here is gone.

Robin.

All right, Victor.

The region is facing another severe weather threat today.

Rob, just back from Tennessee, has the latest Good morning.

Good morning, Robin.

Luckily, what came through yesterday wasn't repeated.

Went through what went through Tennessee but still damage across parts of Mississippi.

This is can Mississippi and they're sending a survey team out to see if this was, in fact, a tornado certainly looks like wind strong enough for that.

All right, here is a low that's causing all this headache.

Motoring down I 10 today and the severe weather threats gonna be from Tallahassee up through southern Georgia.

Then later on today.

Jacksonville to Savannah, damaging winds.

A few tornadoes possible with this and some large hail before it moves off on Friday.

There was a flood component to this.

We'll talk more about that in just a bit.

All right, Rob, Thank you so much.
