That's right Whit.

You can see this massive pile of debris behind me.

There's still very much an active search going on and we don't know the true extent of destruction of this quake across the region.

And tonight the U.S. is vowing to help Whit.

Desperate rescue efforts there.

Thank you.

Meantime back here at home, the flood emergency in Texas has turned deadly.

At least three people have died.

Parts of the state receiving more than a foot of rain.

Flooding roads, submerging cars, first responders performing hundreds of water rescues.

Meantime to the east, the Carolina wildfires exploding in size as hundreds of firefighters race to get the upper hand.

The fire is still just 17% contained.

Is there a physical impact on your firefighters as they're out there working hours on end fatigue?

So this is my local district here.

We've been fighting fire for over a month now.

In South Carolina, the Table Rock complex fire exploding and expanding in size overnight now nearly 17 square miles.

We got a lot of work to do.

It's gonna take a long time to get this contained.

Authorities say charges for those responsible for setting the Table Rock fire are coming, but the priority now is fighting the flames.

And with those gusty winds are picking up again, but it's the dry conditions that have firefighters the most concerned.

That's any fires that break out can spread quickly, but there is rain in the forecast on Sunday and again on Monday and can't come soon enough.

Whit silver lining their faith.

Thank you.

Let's get right to meteorologist Danny Backstrom from our New York station, W.

A.

B.

C.

And Danny, that severe weather threat on the move tonight.

Yes, tonight with East Texas in departs of Louisiana under tornado watch until seven p.m. local time as that heavy rain that we just saw continues from Lake Charles this evening into New Orleans tomorrow.

Then our attention turns to that next major storm system crossing the country set to bring a dangerous severe weather risk to millions this weekend.

The threat begins tomorrow night across portions of the plains, but Sunday brings greater concern with a severe outbreak looking more likely damaging wind, large hail, tornadoes.

They're all possible for many major metro areas from Little Rock to Indianapolis.

This weekend's threat continues east into Monday, bringing the chance for damaging wind, large hail and lightning from the southeast up the I-95 corridor.

So much of the country dealing with several days of dangerous impacts with a difficult weekend ahead.

Danny Backstrom, it's great to have you.

Thanks so much.

Turning now to President Trump's tariff threats and the nosedive on Wall Street.

The Dow plunging hundreds of points to close the week.

Canada's prime minister speaking with President Trump today and how he's now promising to retaliate for the tariffs the U.

S.

Has imposed on Canadian goods.

ABC senior political correspondent Rachel Scott at the White House tonight.

Anxiety over inflation and President Trump's escalating trade war sending markets into free fall.

The Dow plunging more than 700 points.

The president began the day touting a quote extremely productive call with Canada's new prime minister, Mark Carney, saying we quote agree on many things.

What he didn't mention was that Carney told him that Canada would soon retaliate for the tariffs Trump imposed on Canadian products.

You said if that were to happen, that you would be responding with large scale tariffs.

Will you be following through with that promise?

Well, absolutely.

But we had a very good conversation.

We're going to end up with a very good relationship with Canada.

But right now, that relationship is the rockiest it's been in decades.

The old relationship we had with the United States based on deepening integration of our economies and tight security and military cooperations is over.

Trump's steep new tariffs are set to kick in next Thursday, including 25% tariffs on all cars and auto parts made outside the United States.

Economists warn American businesses pay those tariffs and then raise prices for consumers.

By one estimate, the price of a new car could shoot up more than $6000 by next year.

Aman Singh, the general manager at a Toyota dealership in New York, says he's been flooded with calls from shoppers concerned prices are going to rise.

We've been telling them, hey, listen, we have cars here.

If you pick something I have here, it's that price.

President Trump telling those Americans not to worry.

Mr. President, should Americans should Americans buy cars now if they want to avoid higher prices?

No, I don't think so.

I think you're going to have a country that's going to boom.

And despite the markets tumbling, the president showing no signs of backing away from those tariffs.

He says they will go into effect on Thursday, 25% on all cars and auto parts made outside of the United States.

The president says they will be permanent with, as you noted, just days away.

Rachel Scott, thank you.

Now to the second couple making their first official trip abroad, visiting U.S. troops stationed in Greenland.

The plan scaled back, though, amid pushback from people who live there and in Europe over President Trump's stated desire to annex the island.

NBC's senior national correspondent Terry Moran reports from Greenland.

Vice President J.D.

Vance arriving in Greenland's far north today, visiting the Space Force base dubbed the top of the world.

But Vance's real mission here was much bigger.

As you've heard, we have some interest in Greenland from the Trump administration.

And Trump again today declaring in no uncertain terms this is a top U.S. priority now.

We need Greenland, very importantly, for international security.

We have to have many resentful of Trump's demands.

It's a big joke for him that he can just take it.

So Vance sought to gloss over Trump's high-handed approach and drive a wedge between Greenland, which is part of Denmark, and the Danish government, a U.S. ally.
