[Heidi Collins, Cnn Anchor:] Now, for a look at other stories we're watching this morning. American Airlines now being watched closely by the FAA after the carrier had three botched landings in December, which included a Boeing 737. It overran a runway in Kingston, Jamaica. A spokesman for American says the airline is cooperating with the investigation. The United States formally ended a 22-year immigration ban today that stopped anyone with the HIVAIDS virus from entering the country. The ban was imposed at the height of a global panic about the disease at the end of the 1980s. The Census Bureau kicking off an awareness tour today; it will start right here in Atlanta. Stops are also planned in Florida and Alabama. Census workers hope to educate the public about the 2010 count through interactive exercises. From the Midwest to the Southeast, a deep freeze has a grip on parts of the country. We're talking about bone-chilling cold but that was not enough to stop some golfers in Illinois. It's good to have a colored ball, I guess. They grabbed their gloves, their hats, their scarves, of course, for the annual Eskimo Open. Get colored balls instead of the white ones for the snow. In Florida, temperatures way below normal for this time of year, which is not good news for farmers. They are busy trying to protect their crops, especially the oranges.
[Unidentified Male:] If it was frozen, then we would send it to the juice plant. If it was a very small amount, then we may just dump that.
[Collins:] A lot of freeze warnings for Florida today all the way into southern Florida, in fact. I want to check in with meteorologist Rob Marciano in the Severe Weather Center. We have a lot of fun with this cool weather when it happens, but boy some of the consequences are serious.
[Rob Marciano, Ams Meteorologist:] Well, it's not only affecting the citrus farmers but they grow strawberries down there, around the Tampa Bay area and as you mentioned, the freeze warnings dropping all the way south into southern Florida along alligator alley into the Everglades. They had a freeze warning out yesterday and they'll probably get one reposted tomorrow morning. Here are some of the current temperatures. 37 degrees in Orlando. They've rebounded. They were close to freezing in and around Disney World earlier today. 19 degrees, the current temperature in Atlanta, with winds gusting to over 20 miles an hour. That drops the wind-chill in Atlanta into the single numbers right now. 26 degrees in D.C. and 22 degrees, you'll see less wind in New York. Boy, it was blowing yesterday over 50 miles an hour at times. Nine in Chicago, minus nine in Minneapolis. And they're starting to moderate things, albeit briefly. I want to show you this iReport. Check it out. I thought we were going to show princess, the dog.
[Collins:] Oh, we must.
[Marciano:] There's princess.
[Collins:] Oh.
[Marciano:] My goodness. Anyway, nice iReport.
[Collins:] It is.
[Marciano:] I completely forgot who this was Diana Kalenberg, thank you for sending that in. We appreciate the pretty shot out there. No snow in Atlanta although the forecast is for a potential of seeing a dusting of snow early Thursday morning. We have cold air as we mentioned in places and it's kind of chilly right now with that wind chill. Frigid temperatures across the northwest or the northwestern parts of the Great Lakes. Yesterday in International Falls, it got down to minus 37. That's a record. And there's more cold air that's going to be coming down in from Canada that will reinforce the cold air that's already in place right now. Some lake-effect snow is expected across parts of Cleveland, in through Pittsburgh. This shouldn't amount to much more than six to 10 inches maybe, and then a little dusting of snow potentially just south of Memphis as that cold air drives south into the gulf of Mexico. But it shouldn't be too bad. I don't think we'll see much of anything except for a flurry, maybe a light dusting in spots. Thirty-two degrees, you expect the high temperature in Atlanta, 29 degrees in Memphis. And 20 degrees expected in Chicago and a reinforcing shot of chilly air that will come down Tuesday, Wednesday, and Thursday, will bring temperatures back down into 20s. In some cases 30 degrees below seasonal averages, everywhere east it looks like, of the Rocky Mountains. Just try to stay warm. As we mentioned earlier, it's the coldest air of the decade, Heidi. We're not kidding around. So
[Collins:] Yes. Seriously not kidding around. Even though I thought princess, the dog, was going to maybe throw that proverbial boiling water into the air. We could watch it freeze.
[Marciano:] Princess can do some dog tricks but I don't think it's one of them.
[Collins:] No, maybe not. All right. Rob, thank you.
[Marciano:] OK. See you later.
[Collins:] At the airport in Newark, New Jersey, a man bypassed security and created six hours of travel delays. A man walked through the wrong side of the security checkpoint and disappeared into the crowd. And that temporarily grounded some flights. Authorities closed down the terminal to search for the man. They never found him.
[Unidentified Male:] Everybody inside there is waiting because they took everybody off the planes, everybody outside of security. They've got to go back through security. Every single person in the airport has to go back through and do a security check so we can get on our planes and get out of here. It makes me feel like like what the heck is going on with people nowadays. I just I mean I don't know what to expect.
[Unidentified Female:] We had all just gone through the security checkpoint, and we saw security chasing after somebody. Everybody was yelling. The TSA people were yelling 10-9, 10-9. They told everybody to freeze. We couldn't move. They said they didn't want us to reach into our bags. We just basically stood there.
[Collins:] And check out this iReporter photo. Anthony Cemara says airport officials were herding people away from the gates and corralling them into the baggage claim area. He says people really didn't know what was going on, They were confused, and, yes, a little nervous too. Fears over terrorism both here and abroad. The White House says Al Qaeda in Yemen is apparently planning attacks against the U.S. targets there. So for the second straight day, the U.S. embassy is shut down in Yemen's capital. The British and French embassies also closed because of the security threat. And heightened concerns of a terror attack is obvious at the airports around the world. Beginning today international travelers bound for the U.S. will face tighter screenings in 14 countries. Yemen is looming larger on Washington's radar now as evidence mounts that it's becoming a stronghold for Al Qaeda. President Obama has addressed the rising threat and his top military leader in the region visited the country over the weekend. CNN's Barbara Starr joining us now from the Pentagon with more on this. Barbara, what more can you tell us about General Petraeus' meeting with Yemen's president.
[Barbara Starr, Cnn Pentagon Correspondent:] Well, you know, Heidi, he stopped in Yemen over the weekend for just a couple of hours for a very closed door meeting with President Salih of Yemen, and just a small group of officials there. Yemen now front and center for 2010. The new view on Yemen is that it is a country now that can quite its Al Qaeda members can reach out and touch the United States. The Detroit incident seems to prove that now. So General Petraeus went, taking messages and information, we're told, from President Obama to the leadership in Yemen. All of this now is about sharing intelligence and sharing targeting information about where Al Qaeda is hiding in Yemen and how to get to them. General Petraeus spoke very rare comments by him about Yemen over the weekend.
[Gen. David Petraeus, U.s. Centcom Commander:] It's a country that has a lot of challenges, the Hutis in the north and some southern secessionists in the south, the reduction in oil production although gas is going up thankfully. But a youth bulge. Many of the challenges of countries that are in the process of development. Rugged terrain, tribal areas, and so forth. So very important, indeed, that Yemen has taken the actions that it has and, indeed, that not just the United States but countries in the region, its neighbors and so forth, have provided they in particular have provided significant assistance.
[Starr:] But what is next for the United States, Heidi, more intelligence sharing, more targeting information for the Yemeni military, more training of their security services, and everything that the U.S. military and the U.S. government can do to press the Yemenis to go after Al Qaeda in their country and behind the scenes possibly, possibly more U.S.-led missions against Al Qaeda. Don't look for boots on the ground. Nobody's talking about that.
[Collins:] No.
[Starr:] But try to push the Yemenis out in front and make them go after Al Qaeda.
[Collins:] Yes. Understood. We need the cooperation there obviously. I wonder though do we know any more details, Barbara, about tomorrow's meeting with intelligence officials?
[Starr:] Well, the president is scheduled to meet at the White House. The phrasing we heard is "with all relevant agency head." Everyone who could possibly have something to offer about what went wrong in this Detroit situation, where the failures were in international airline security. This whole business of the watch list, searching people, scans, all of it. You know, John Brennan yesterday saying on CNN's "State of the Union," "this wasn't a 911 but this was some failure of some of the bureaucracy and the president wants to hear exactly what did not happen correctly, Heidi.
[Collins:] Right. Understood. Of course, we're going to be following the story throughout the morning here. We've got more information too, Barbara, on those new TSA guidelines that went into effect for international flights today as well. We'll talk about that. Barbara Starr, our Pentagon correspondent.
