I think what we have going on here, in the last 24hours, is the greatest number of Americans rescuedby a helicopter since Hurricane Katrina.

Lt.Colonel Utterback talking about the severeflooding in Colorado.

We're going to have more on that in just a moment.

First today, though, the U.S. and Russia work out a deal-you're seeing U.S. Secretary of StateJohn Kerry on the left and Russian Foreign Minister Sergey Lavrov on the right.

They met in Switzerland late last week to talk about Syria's supply of chemical weapons.

And they came up with steps for Syria's to hand over control of those weapons.

Here's the plan: step one: within oneweek, Syria has to offer a comprehensive list of all of its of chemical weapons.

Step two, international inspectors must be in Syria no later than November.

And step three, all of Syria's chemical weapons materials must be destroyed by the middle ofnext year.

This deal could prevent a military strike against Syria, but Secretary Kerry says the threat offorce is still an option to make sure Syria follows through.

Groups in Syria that are opposed to the country's government aren't sure if that will happen.

They say the government has a long history of empty promises.

And U.S. Senator John McCain says he and some of his colleagues don't believe the deal overSyria's chemical weapons will do anything to resolve that country's civil war.

Back to the flooding in Colorado.

Officials say, it is responsible for several deaths there so far.

Yesterday, about 480 people were still unaccounted for.

You can see in this YouTube video what some people in Colorado are dealing with.

Water rushing by their homes up as high as some windows.

Government agencies say flooding claims nearly 100 lives per year,

that's more than other types of severe weather, and most of those deaths involve vehicles.

Officials say people try to drive through flooded areas without realizing how powerful themoving water can be.

12 to 18 inches of flowing water can carry away most vehicles, best advice is if you come to aflooded road, just turn around.

Nick Valencia has more on the impact of this flooding in Colorado.

Days of intense rain have left swollen creeks, flooded roads and damaged bridges in the stateof Colorado.

Dealing with the weather and its aftermath is proven to be difficult and dangerous.

In Aurora, water and hail trapped drivers in a parking lot.

Most people there were able to walk out, but for many others in the Boulder area the only wayout, by helicopter.

Hundreds have been picked up, many of those are trapped in towns where severe floodingshut down roads living them stranded.
