have you watching. First up, every city that's hosted the Olympic Games in recent years has faced

considerable challenges. Rio de Janeiro, Brazil, is no exception. The cost of hosting the games which

is in the billions, keeping residents and visitors safe. Just making sure they can all get around from

place to place, and building many of the venues where athletes will compete. These are common

obstacles, but there are a number of unique challenges to Rio and Brazil as a whole that officials

worldwide are concerned about. Olympic organizers and city officials say, these games which are

the first ever to be held in South America will be a big success. So why do some critics have doubts?

Well this is been a particularly rough run up to the Olympic Games, which are scheduled to

start here in Rio in just over two months. A whole set of challenges facing not only Rio the

host city, but Brazil as a whole.

It's hard not to be seduced by Rio De Janeiro. The spectacular cities soon to be the host of the

2016 Summer Olympics. Two months before the start of the game construction crews are

putting in the final touches at the Olympic venues.

Everything is gonna be ready on time. We are gonna deliver the park fully commissioned on the 24th of July.

But despite Rio's beauty the city in Brazil it as a whole are facing some pretty daunting challenges.

A whole series of unexpected set backs leading some to wonder, are Rio's Olympics somehow cursed?

Just days ago a warning for more than 100 international doctors, calling for the games to be postponed

or move, because the mosquito born Zika virus could threaten an expected half a million foreign visitors.

That view rejected by the World Health Organization which does advise pregnant women to avoid

the Olympics entirely, because of the risk of severe deformities to unborn children.

And then there's the political and economic crisis.

Turmoil, after congress suspended Brazil's elected president in an impeachment process last month

and high level corruption scandals. During the worst economic recession in generations, which has

left more than 10 million Brazilians unemployed. The economic hardship is aggravating Rio's endemic

problems with violent crime. Daily gun battles between police and drug gangs in the cities impoverished

favelas as well as a surge in robberies.

This month, members of the Spanish Olympic sailing team mugged at gunpoint.

And we just turned around to see what was happening and we saw the pistols.

Olympic sailors also worried about Rio's notoriously polluted bay,

a dumping ground for much of the city's raw sewage.

We don't wanna swim in it.

Rio's mayor warns, this isn't a first world city.

Don't come here expecting that everything will be perfect. We live in a country that has economic crisis,

a country with lots of inequality. With all the problems that we've seen concerning corruption, bribes,

but the city will be much better than it was when we got the games.

But even one of the mayor's new infrastructure projects is now a deadly failure. This brand new

spectacular cliff side bike path was supposed to be a showcase project for the Olympics. Instead,

it became a tragic setback when the waves took out part of the trail, killing two people last month.

In the turbulent run up to the Olympics, a virtual storm of bad news that leaves you wondering

what could possibly happen next.

Across the Pacific Ocean, South East China is where we're starting today's call of the roll in

the City of Pashan. Thank you for watching from Nanhai Senior High School. To the US state of

West Virginia, we've got some Vikings there. Petersburg High School is in the City of Petersburg,

and watch out for the Hornets, they're making a buzz in Charlotte North Carolina, where

you'll find Albemarle Road Middle School. The term 500 year flood event basically means there's

a rare 1 in 500 chance that a particular flood would hit in a given year.

Southeast Texas has seen two of these 500 year flood events in two months, what a CNN meteorologist

described as very bad luck. Last week, there were record setting rains in the region at one point the city

of Brennan got 19 inches of rain in 48 hours. It stopped following last Friday night, but not before swelling

flood waters that killed six people, some of whom were trapped in cars and high water.

The National Weather Service has given several warnings telling people not to drive through flooded

areas and to be careful near river banks. Hundreds of homes have been flooded or swept away,

another storm is in the forecast for later this week. Today is the official start of the Atlantic hurricane season,

it runs from June 1st to November 30th.

The forecaster say that these storms can form at any time this is just when their more likely.

Predicting how many storms will form in a given season is not an exact science and predictions are

often inaccurate. But they give coastal residents, emergency workers and insurance companies

an idea of what to look out for.

NOAA has just released their numbers for the upcoming hurricane season. Their predictions on

active this season will be, and they've actually predicted a very normal season. 10 to 16 rain storms,

4 to 8 hurricanes, and 1 to 4 major storms. It's pretty much all in line with what the other agencies are saying,

12 to 14 named storms. Now a normal year, you may say so what? But it's actually been a while

since we've had a normal year. You have to go back to 2012, ever since then we have had below

normal seasons. So forecasting a normal season this year will actually mean more storms possibly.

One reason we have had some pretty slow years is because of El Ni o. The jet stream shifts to the South

during an El Ni o year increasing the wind shear which will rip those storms apart. But we are

forecasted to go into La Ni a which means that jet stream will shift back up to the North.

We'll have decrease in wind shear, and it could be just that perfect environment to get some

of the storms going in the Atlantic.

CNN has used a lot of hurricane footage that people captured on their phones. Digital photography

is something we just tend to use without thinking about. But 41 years ago, when the first digital camera

was made it weighed about 8 pounds. It took 23 seconds to record it's first picture and it's resolution

was 101 megapixel. So maybe all that's why Kodak wasn't in a hurry to invest in the technology.

The great irony of Frankenstein, is that the doctor's greatest discovery creating a living, breathing

human from dead matter led to his demise. Kodak can relate.

One of their engineers, Steven Sasson invented the first digital camera in 1975.

For the invention of the digital camera revolutionized.

They called the technology filmless photography, but they were never able to capitalize on it. In fact,

their competitors trounced them in the digital photography space. And in 2012, a 131 years after

its founding, the company file for bankruptcy protection. By then, an estimated 2. 5 billion people

owned digital cameras and that's changed business too, especially this business, journalism.

Video and images captured on digital cameras could be instantly reviewed and transmitted all across

the world. The first journalist to use a digital camera for the Associated Press did so at the first

Bush inauguration in 1989. And cellphone cameras have made every citizen a potential reporter.

Time and time again, footage captured by amateurs on digital cameras has been vital first hand sources

of information, even medicine has benefited. Doctors can see inside your body thanks to tiny

digital cameras. And then they can store and share those images quickly and easily with colleagues

across the globe. The list goes on and on, but if you could excuse me, I have to go FaceTime with my mom.

On the golf course, you might encounter a bunker or a lake hazards you generally want to avoid.

Here is another kind. This massive, scaled, reptilian, beast of a hazard was seen in the greens at

a Florida golf course recently. The alligator is estimated to be 15 feet long. The man who shot this

video said the thing was so big it looked like two guys in an alligator suit. Didn't cause any problems

besides maybe abject terror. Good thing no one tried to club it, its teeth could leave a hole in one attacker.

It doesn't need to take a shot to take a slice and it's simple presence is off putting. Know what

a golfer yells when an alligator's on the course? Carni-fore! I'm Carl Azuz, and we'll you gator.
