BOLDUAN: It's more breaking news coming in on this Labor Day holiday, a tropical storm bearing down on the Florida Keys. Now, hurricane watches are in effect for parts of the Gulf Coast. Let's go over to CNN Meteorologist Chad Myers, who's tracking this storm. What's the latest, Chad?</s>CHAD MYERS, CNN METEOROLOGIST: Well, the latest at 11 O'clock was that the storm is still getting stronger. Kate, this is absolutely an overachiever storm. 30 miles per hour when I walked in the door this morning, and then they bumped it to 35. All of a sudden, it hit the very warm water in the Everglades -- I know you think of it as land, but it's really more of just a warm, hot swamp -- and the storm took off. It really began to develop and became a much stronger storm in the past three to four hours. And yes, hurricane watches are in effect for Mobile, almost all the way over to southeastern Louisiana. Now, it's forecast to be a 70-mile-per-hour storm tomorrow night - late tomorrow night with a landfall here. This is plus or minus 20%. We do a very good job at direction, but it's that speed that may not be exactly perfect. And so, we have these storm surge watches and warnings here - three to five feet of storm surge; that's a life- threatening storm surge there, across parts of Louisiana, from Bay St. Louis over to Pass Christian. That's the area we're talking about, heavy rainfall as well. We'll keep watching this. This has always been a storm that had no future. Now all the sudden, we're going, holy cow, the water is really warm. And this may be a much bigger storm than anticipated. Hurricane Hunter in it right now, about 50 miles per hour almost.</s>BOLDUAN: Almost. Well, I think a lot can happen in the next few hours. We'll be keeping close with you to get a good idea. I really appreciate it, Chad. Thank you so much. And thanks for joining us on this Labor Day. Inside Politics with Dana Bash for us, right now.
