A U.S. presidential rally, a U.S. correspondents' dinner, and a U.S.-organized march
lead off this month's coverage on CNN 10. We're reporting on a destructive and
deadly storm system that struck the country and bringing you facts about tornadoes.
And we're introducing a new CNN Hero who's helping teenagers in the Middle East.
TRANSCRIPT
CARL AZUZ, CNN 10 ANCHOR: Hi. I'm Carl Azuz. Welcome to a new week, a new
month and a new edition of CNN 10.
We're going to start today by recapping a few events from the weekend. It was an
eventful one in the U.S.
Saturday night, on his 100th day in office, President Donald Trump attended a rally in
Harrisburg, Pennsylvania. He was with the crowd that helped him win the 2016
election.
(BEGIN VIDEO CLIP)
DONALD TRUMP, PRESIDENT OF THE UNITED STATES: And could not possibly be
more thrilled than to be more than 100 miles away from Washington swamp, spending
my evening with all of you, and with a much, much larger crowd and much better
people, right?
(END VIDEO CLIP)
AZUZ: President Trump has frequently taken aim at the media, accusing organizations
of not covering him fairly and he was contrasting the Harrisburg rally with the White
House correspondents' dinner, typically, an event where the president and the media
trade jokes about each other and themselves.
President Trump was the first U.S. leader since President Ronald Reagan not to
attend the correspondents' dinner.
(BEGIN VIDEO CLIP)
JEFF MASON, PRESIDENT, WHITE HOUSE CORRESPONDENTS' ASSOCIATION:
But the values that underpin [support] this dinner have not changed. In fact, I think
they've been reinforced. We are here to celebrate good journalism. We are here to
celebrate the press, not the presidency.
(END VIDEO CLIP)

2. AZUZ: Also on Saturday, tens of thousands turned out at Washington, D.C. for what
organizations called the People's Climate March. There were demonstrations like this
in several other U.S. cities and abroad. The Trump administration has worked to
remove government regulations on fossil fuels, regulations put in place by the Obama
administration. And marchers believe the Trump administration's policies will
negatively impact the environment.
President Trump has said he's committed to protecting the environment, but that
greener policies must not come at the expense of jobs.

AZUZ (voice-over): Ten-second trivia:
How do most tornadoes rotate in the Northern Hemisphere?
Clockwise, counterclockwise, latitudinally, or anticyclonically?
In the Northern Hemisphere, most tornadoes, though not all of them, rotate
counterclockwise.
(END VIDEO CLIP)
AZUZ: First responders don't yet know the full extent of damage caused by violent
storms over the weekend. They have reported that several U.S. states were hit --
Arkansas, Mississippi, Missouri, Oklahoma, and Texas. At least eight people died and
dozens were injured. Numerous water rescues had to be made in Missouri as
widespread flooding led authorities to close 150 roads.
Officials say several tornadoes touched down in Texas, leaving a path of destruction
15 miles wide. Homes and buildings, cars and trees were demolished. The system
began lashing the Southwest and Midwest on Friday, and last night, it was moving
east, putting more than 30 million Americans under flash flood watches and warnings.
(BEGIN VIDEOTAPE)
CHAD MYERS, AMS METEOROLOGIST: Technically, a tornado was just a violent,
rotating column of air coming out of the bottom of the thunderstorm. But it takes a
lot to get that violently rotating column to come out.
SUBTITLE: CNN Explains: Tornadoes.
MYERS: All you need for a tornado really to form, though, are thunderstorms and a
jet stream. That jet stream is a loft [throw, strike]. It makes the energy, if you
have moisture at the surfaces, dry air, cold air, pushing that moisture up, you can get
a tornado to form in any state.

3. Those days where all the ingredients combine, you get the humidity, you get the dry
air, you get the jet stream, you get upper energy in the jet stream. You get winds
churning [agitate, swirl] as you go aloft. The higher you go, the winds actually change
direction. That can cause storms, those things all cause storms to exist and get big.
Those are the ingredients that caused a big tornado day.
SUBTITLE: Rating tornadoes.
MYERS: So, now the EF Scale, Enhanced Fujita Scale, starts at zero, goes only to
five, and anything above 200 miles per hour is considered an EF-5 tornado.
If you have a zero, you're going to lose singles [roof tiles]. A one, you may lose a
couple of boards on the roof.
A two, you lose all the windows and maybe even a wall.
A three, EF-3, you will lose a couple of walls on the outside, but there will still be a
part of a home standing.
An EF-4, most of the home is gone, but you'll still the refrigerator, you'll still see a
closet and you'll still have the bathroom.
An EF-5, you cannot find the house. It's completely gone.
We don’t know how big that Fujita Scale will be, how big that tornado literally until
we look at the damage.
SUBTITLE: Tornado Alley.
MYERS: We have this almost this triangulation that no other country in the world, no
region in the world has. We have the Rocky Mountain to our west, we have the Gulf of
Mexico in our south, we have Canada and very cold air masses coming down from the
north, all of those things combined make Tornado Alley. Typically, the Plains, Texas,
Oklahoma, Kansas, Nebraska, all the way to Chicago, as far south as the Southwest,
including Georgia and Alabama, that's basically the new or the bigger Tornado Alley.
SUBTITLE: Tornado Safety.
MYERS: The greatest threat of a tornado is being hit by something that the tornado
is moving. If you're outside or if you're not protected inside, if you're hit by a 140-
mile-per-hour two-by-four [2x4 inch timber], you're going to be killed.
So, you need to be inside and the lowest level, somewhere in the middle of the home
away from windows.

4. When you hear the word "warning" and you hear your county, that's when you need to
take cover.
When you hear the word "watch", that means something might happen today. Let's
have a plan.
When you hear the word "warning", it's too late to make a plan. You need to already
have the plan. Warning is the long word, it's the bad one.
(END VIDEOTAPE)
AZUZ: Now for a report on a CNN Hero. Shanti House is named for a Sanskrit word
that means peace and tranquility. It was started by a woman who learned firsthand
what it's like to be homeless, living on the streets of Boston, Massachusetts, as a
teenager.
She eventually got her life back on track and returned to her native Israel to bring
peace and tranquility to teens today.
(BEGIN VIDEOTAPE)
UNIDENTIFIED FEMALE (translated): I've had a difficult life. A lot of violence,
abuse in every way. At age 16, I ended up in the streets. Life in the streets was very
hard. It's a life no kid should live.
MARIUMA BEN YOSEF, CNN HERO: To be homeless in a young age, it's very lonely.
When I was 14 years old, I was living in the streets. I slept on benches and ate from
garbage with other children that didn't have a home. It was something that I
couldn't forget.
At the age of 20, I opened my home to serve dinner to children, teenagers, and
people that didn't have any place to eat. Before I know it, I set the place for all
these children to sleep in my own home.
That was more than 30 years ago. Now, we have two homes. We provide temporary
home and long term support for children at risk.
My goal is that every child that comes through this door will feel at home. They will
feel so secure and so happy.
This is my children. This is my life.
We're there for them 24/7.
(translated): Did it hurt you that your mother didn't come? You know, if she didn't
come, that is something she has to deal with herself.

5. UNIDENTIFIED FEMALE (translated): You're family and that's the most important
thing.
UNIDENTIFIED FEMALE (translated): When I got to the Shanti House, I was
taught that I can achieve anything.
BEN YOSEF (translated): How was your week?
UNIDENTIFIED FEMALE (translated): I always wanted to finish school and they
made that dream come true.
Suddenly, I see a big letter from everyone at the Shanti House and it says how much
you're proud of me and how much you love me. And I realized just how much you're
with me in every situation.
(APPLAUSE)
UNIDENTIFIED FEMALE (translated): The Shanti House is not just a roof over my
head, it's my family.
BEN YOSEF: I didn't have a family, neither these kids. So, (INAUDIBLE) a cosmic
family.
I know exactly what they're going through. I want all these children to see that
there is always life in the dark. We can conquer it.
(END VIDEOTAPE)
AZUZ: Fire goats. It sounds like goats that breathe fire. But these are more like
firefighting goats. Smokey the Bear might have said only you can prevent foreign
fires, but these animals can help too. they naturally clear out flammable undergrowth
in Anaheim, California, by eating it. City fire department uses about 175 goats. They
helped patrol 27 acres of vegetation with their teeth, leaving little behind for a
potential fire to chew on, taking a bite out of danger.
So, maybe they don't actually breathe fire, but as long as they keep their chins up
and the undergrowth under grown, residents probably won't mind being goaded into
reaching safety goats by employing these goat to weapons in the bahhhttle against
blazes.
