    Hello and welcome to CNN 10. I'm Allison
  • 00:00:14
    Chinchar filling in for Koi just for
  • 00:00:16
    today. He's actually out on the West
  • 00:00:17
    Coast shooting some special content for
  • 00:00:19
    later this summer. So if you're in Los
  • 00:00:22
    Cusus, New Mexico today, you might see
  • 00:00:24
    his bald head out and about. I'm excited
  • 00:00:27
    to be here with you. We've got a great
  • 00:00:28
    show for you today. So, let's go ahead
  • 00:00:30
    and get started. We begin today with
  • 00:00:33
    severe storms that battered a large area
  • 00:00:35
    of the US and triggered dozens of
  • 00:00:37
    tornado reports over the last week. Now,
  • 00:00:39
    late last week, an EF3 tornado rocked
  • 00:00:42
    the St. Louis area, damaging or
  • 00:00:44
    destroying thousands of buildings, and a
  • 00:00:47
    powerful EF4 tornado tore across
  • 00:00:49
    southern Kentucky. The National Weather
  • 00:00:52
    Service officials say it was the
  • 00:00:53
    deadliest tornado in the history of
  • 00:00:56
    their area with London, Kentucky hit
  • 00:00:58
    particularly hard. Now, another storm
  • 00:01:01
    hit parts of Kansas, Oklahoma, and
  • 00:01:03
    Colorado late on Sunday where homes were
  • 00:01:06
    severely damaged. Roads were blocked and
  • 00:01:09
    cars were overturned. The storms were
  • 00:01:11
    powerful enough to toss semitrs into a
  • 00:01:14
    field in Kansas. A powerful EF1 tornado
  • 00:01:17
    tore apart homes and brought down trees
  • 00:01:20
    in Nebraska. We went into the bathtub
  • 00:01:24
    and then put pillows and blankets and I
  • 00:01:25
    just laid on top of my daughter so that
  • 00:01:27
    if anything came through I would
  • 00:01:28
    hopefully get me and her. It sounded
  • 00:01:30
    like a train basically and just really
  • 00:01:33
    windy and then you could hear stuff
  • 00:01:34
    hitting against like the house. More
  • 00:01:36
    tornadoes touched down as the severe
  • 00:01:38
    weather pattern continued earlier in the
  • 00:01:40
    week battering homes and power lines in
  • 00:01:43
    the small city of Plena, Kansas. Now,
  • 00:01:45
    thankfully, no one was injured there.
  • 00:01:47
    And as the severe weather moved east,
  • 00:01:49
    millions of people in parts of the
  • 00:01:51
    Mississippi, Ohio, and Tennessee valleys
  • 00:01:54
    braced for new rounds of storms as they
  • 00:01:56
    were still cleaning up debris from the
  • 00:01:58
    previous storms. It is simply unsafe to
  • 00:02:02
    be around that much debris with this
  • 00:02:04
    level of of wind. Now, further east,
  • 00:02:07
    tornadoes touch down in parts of
  • 00:02:09
    Alabama. Let's head to the weather
  • 00:02:11
    center to show you what meteorologists
  • 00:02:13
    like myself look for when these storms
  • 00:02:15
    form. This is a two-dimensional look at
  • 00:02:18
    a storm on radar, but meteorologists see
  • 00:02:21
    a tornado. But what is it exactly that
  • 00:02:23
    meteorologists see? Well, let's take a
  • 00:02:26
    look. The yellow and green colors you
  • 00:02:28
    see here are going to be your very heavy
  • 00:02:30
    rain in the storm. The red color
  • 00:02:33
    indicates your hail core. And then all
  • 00:02:35
    the way down there, the purple circle,
  • 00:02:37
    that's where your tornado is going to
  • 00:02:39
    be. Meteorologists often refer to it as
  • 00:02:41
    the hook echo because of the hook shape
  • 00:02:43
    that it ends up taking. But these aren't
  • 00:02:45
    the only features we look for. We also
  • 00:02:48
    have to take a look at the winds inside
  • 00:02:50
    the storm. Imagine this flag pole was
  • 00:02:52
    inside of our storm and the flags going
  • 00:02:55
    all the way up to the very top of the
  • 00:02:58
    cloud. The thing is the wind changes
  • 00:03:00
    direction as you go up. So this
  • 00:03:03
    naturally creates that rotation
  • 00:03:05
    necessary for funnel clouds and also
  • 00:03:07
    even tornadoes. So now let's take a look
  • 00:03:10
    at the base of that storm. What you have
  • 00:03:13
    is you have very warm inflow, warm air
  • 00:03:15
    coming into the storm and rising because
  • 00:03:18
    that's what warm air does. It goes up.
  • 00:03:21
    But you also have cold air coming down
  • 00:03:23
    from the tops of the clouds and sinking
  • 00:03:25
    all the way down towards the base. Now
  • 00:03:28
    together, these help to create wind
  • 00:03:30
    shear down near the perimeter. And that
  • 00:03:32
    is what helps create some of the more
  • 00:03:34
    violent tornadoes. Now, what if your
  • 00:03:37
    tornado has been on the ground for at
  • 00:03:39
    least a little bit? Then you start to
  • 00:03:41
    get this, the debris cloud, which is
  • 00:03:44
    essentially a collection of all of the
  • 00:03:46
    stuff the tornado has been able to pick
  • 00:03:48
    up. Everything from dust to trees to
  • 00:03:51
    even homes. Now, tornadoes can happen
  • 00:03:54
    almost anywhere. So, it's important to
  • 00:03:56
    know the differences between the three
  • 00:03:58
    key alerts for these storms. you have a
  • 00:04:01
    tornado watch, a tornado warning, or a
  • 00:04:04
    tornado emergency. And the National
  • 00:04:07
    Weather Service has come up with a
  • 00:04:08
    pretty clever analogy to help us all
  • 00:04:11
    remember tacos. So, a taco watch is we
  • 00:04:14
    have all of the ingredients, but we
  • 00:04:17
    haven't yet assembled the tacos. Simply
  • 00:04:20
    meaning we have all the ingredients for
  • 00:04:22
    a tornado and they're present, but you
  • 00:04:24
    need to make sure you know your
  • 00:04:25
    emergency plans and can be ready to go
  • 00:04:28
    to a safe place when the taco is made.
  • 00:04:31
    Now you have a taco warning. This means
  • 00:04:33
    the taco is made or in other words, a
  • 00:04:36
    tornado has either been seen or
  • 00:04:38
    indicated by weather radar. So the
  • 00:04:40
    threat of danger is imminent. You want
  • 00:04:43
    to move to an interior room on the
  • 00:04:45
    lowest floor of a sturdy building and
  • 00:04:47
    avoid all windows. Also, anyone in a
  • 00:04:50
    mobile home should safely move to a more
  • 00:04:52
    substantial shelter. And the third and
  • 00:04:55
    highest alert level is a tornado
  • 00:04:57
    emergency. Now, no tacos here, but this
  • 00:05:00
    alert is reserved for rare situations.
  • 00:05:03
    It's issued when a confirmed and violent
  • 00:05:06
    tornado poses a substantial risk to life
  • 00:05:08
    and property, and it means it's time to
  • 00:05:10
    take shelter immediately, preferably
  • 00:05:14
    underground. 10-second trivia. Now, what
  • 00:05:17
    country has the highest density of robot
  • 00:05:21
    workers? Is it Japan, China, Germany, or
  • 00:05:26
    South
  • 00:05:28
    Korea? Your answer here is South Korea.
  • 00:05:32
    Currently home to over 1,000 industrial
  • 00:05:35
    robots per 10,000 employees in the
  • 00:05:38
    manufacturing
  • 00:05:40
    industry. Engineers at the Massachusetts
  • 00:05:42
    Institute of Technology, better known as
  • 00:05:45
    MIT, have just created a tiny robot the
  • 00:05:48
    size of an AirPod. Kind of like an
  • 00:05:51
    insect. It moves by hopping and weighs
  • 00:05:54
    less than a paperclip with a
  • 00:05:56
    spring-loaded leg and four flapping
  • 00:05:58
    wings. Here's how it works.
  • 00:06:01
    The passive leg, just like a tiny pogo
  • 00:06:04
    stick, make sure the robot can bounce
  • 00:06:06
    back efficiently from the
  • 00:06:08
    ground. On the other hand, the flapping
  • 00:06:11
    wing modules ensure the robot stay
  • 00:06:13
    upright for stability. So why does the
  • 00:06:16
    world need such a small cyborg? The
  • 00:06:19
    creators say the robot could be used in
  • 00:06:21
    search and rescue operations because it
  • 00:06:24
    can navigate confined spaces and
  • 00:06:26
    withstand rough terrain. It's official.
  • 00:06:29
    Flag football will be making its debut
  • 00:06:32
    in the 2028 Los Angeles Olympics. And
  • 00:06:35
    you may be seeing some of the biggest
  • 00:06:37
    names in the NFL, representing the US in
  • 00:06:40
    the sport. Flag football is the no
  • 00:06:42
    contact version of American football
  • 00:06:45
    that swaps tackles for grabbing flags
  • 00:06:47
    the opponents are wearing. While the
  • 00:06:50
    International Olympic Committee approved
  • 00:06:52
    the inclusion of the sport back in 2023,
  • 00:06:55
    the NFL just voted to allow a maximum of
  • 00:06:58
    one player per NFL team to go for the
  • 00:07:01
    flag football gold. Plus, each club's
  • 00:07:04
    designated international athlete will be
  • 00:07:07
    able to play for his country. And the
  • 00:07:09
    Olympic flag football competition will
  • 00:07:11
    also include women's teams. Now to South
  • 00:07:15
    Korea, where a trip to the nation's
  • 00:07:17
    largest fish market can be an
  • 00:07:19
    overwhelming sensory experience. There
  • 00:07:22
    are rows of hundreds of vendors, a wide
  • 00:07:26
    variety of live seafood, and a whole lot
  • 00:07:30
    of smells. Luckily, our elite Marcus
  • 00:07:32
    went there to give us some tips on
  • 00:07:34
    making the most of a visit.
  • 00:07:39
    We are in Noranin, which is the oldest
  • 00:07:41
    and biggest fish market in Seoul. Think
  • 00:07:44
    of it as like a giant mall, but the only
  • 00:07:46
    thing you can buy is live fish and
  • 00:07:48
    shellfish.
  • 00:07:53
    It's just bigger. It's way bigger. Uh
  • 00:07:56
    there's much more variety to that. It's
  • 00:07:58
    fresher, I believe.
  • 00:08:00
    Norian originally was opened in 1927,
  • 00:08:04
    but it moved here to this location in
  • 00:08:05
    the 1970s, which is where it's been ever
  • 00:08:23
    since. Okay, it's chewier than I
  • 00:08:25
    expected.
  • 00:08:35
    in my mouth.
  • 00:08:38
    A couple things that you should know if
  • 00:08:40
    you come here. First of all, all the
  • 00:08:42
    fish is live. So that means you can pick
  • 00:08:44
    it out and then take it upstairs and
  • 00:08:47
    have someone cook it right there so that
  • 00:08:49
    you can eat it. It's about as fresh as
  • 00:08:50
    it gets. You're also totally welcome to
  • 00:08:53
    haggle. In fact, they kind of expect it.
  • 00:08:56
    Another important thing if you visit,
  • 00:08:58
    make sure that you wear good footwear.
  • 00:09:00
    The floors are wet and I'm an idiot who
  • 00:09:02
    showed up in ballet flats. So, you want
  • 00:09:04
    to take a cue from all the other people
  • 00:09:06
    who are here. Try a pair of tennis shoes
  • 00:09:08
    or some rain
  • 00:09:13
    boots. Today's story of getting a 10 out
  • 00:09:16
    of 10 goes to a school resource officer
  • 00:09:19
    doing a good deed for a student in need.
  • 00:09:22
    Officer Brett Berer noticed one of his
  • 00:09:24
    high school seniors was due for an
  • 00:09:27
    upgrade. Shawn Merritt was born with
  • 00:09:29
    cerebral pausy and relies on an electric
  • 00:09:32
    wheelchair to get around. But that chair
  • 00:09:34
    had seen better days and Ber decided to
  • 00:09:37
    take action. I went out and talked to
  • 00:09:39
    some of my good friends and people of
  • 00:09:41
    the neighborhood and the community and
  • 00:09:43
    explain the situation and before I could
  • 00:09:45
    get past Shawn Merritt, which is Shawn's
  • 00:09:47
    name, they were all in. The community
  • 00:09:50
    rallied to raise money and buy senior
  • 00:09:52
    scholarship night. Ber surprised the
  • 00:09:55
    graduating senior with a new wheelchair
  • 00:09:58
    complete with upgraded features and even
  • 00:10:01
    Bluetooth speakers. A gift Merritt says
  • 00:10:03
    will remind him of home as it helps him
  • 00:10:06
    transition to college life in the fall.
  • 00:10:09
    All right, superstars. It's time to send
  • 00:10:11
    out a shout out to Mr. O and all of the
  • 00:10:14
    Patriots at Colonia Middle School in
  • 00:10:16
    Colonia, New Jersey. Thanks for spending
  • 00:10:19
    part of your day with us and thank you
  • 00:10:20
    all for letting me spend the day with
  • 00:10:22
    you. Koi will be back tomorrow to finish
  • 00:10:24
    out the rest of the week. It's been a
  • 00:10:26
    blast getting to fill in and host the
  • 00:10:28
    best 10 minutes in news. Have a great
  • 00:10:30
    day, everyone.
