BERMAN: We have a weather alert for you. The National Hurricane Center says there is a 90 percent chance of a tropical system developing in the Gulf as early as today. The system could drop as much as 20 inches of rain. CNN meteorologist Chad Myers with the forecast. People need to pay attention, Chad.</s>CHAD MYERS, AMS METEOROLOGIST: Yes, you bet, John. Computer models anywhere from a 60 mile-per-hour storm to a category two hurricane. That's the spread right now. We always talk about the cone, but there's also a miles per hour spread too. There's the zone. 90 percent chance of development. We'll get to that. This weather is brought to you by Xyzal, all night, all day allergy relief. So where does it go? It's actually comes off the coast of Florida into the Gulf of Mexico now. So still very disorganized. But the hurricane hunter aircraft will be there later today to look for the center. Where does the center go? Likely to Louisiana. And the models are saying somewhere probably near Lafayette, Louisiana, later on this week. Probably making landfall on Saturday. Now, the rub is the longer it stays in the water, the stronger this will get, because there's more time. I just checked buoys out there. The water temperature is 85 degrees there. So 85 degrees could make a very intense hurricane grow quite rapidly. The good news is, it isn't going to have three or four days in this water. New Orleans, though, you could see, with the American models predicting 10 inches of rainfall. And, Alisyn, with the flood gates closed, all of that water has to be pumped out. We'll keep watching it all weekend.</s>CAMEROTA: Oh, we know you will, Chad, thank you very much for that warning.</s>MYERS: You're welcome.</s>CAMEROTA: So, listen to this. Passengers on a flight to Baltimore watch in horror as part of their plane's engine comes off in mid-air. The dramatic moments from inside the plane, next.
