Transcript for Tropical Storm Isaac's Path Changes, Might Miss RNC
tropical storm isaac. Team coverage this morning. Sam, it looks less likely it will score a direct hit on tampa and the republican convention. But it may be more of a threat to the gulf coast. All that out and brand-new information this morning. Matt gutman's in tampa right now. We're going to show you everything we know about the new information. We're going to start with the 3d view that we like to put up with the storm like this. It shows where the higher clouds are. And the big circulation on the storm is right there. It is a good-sized system. We're looking at two areas of strong thunderstorms that are right there. The point of that is that all of this will move a little towards the north. The heavier rain will swing across puerto rico and haiti. Already, we have pictures coming out of the first wind fields to move across puerto rico. Knocked down a lot of trees and power lines. There's more of that ahead in the next few hours. Our big deal or what we know now more about that storm system is the fact that this thing is crawling over many islands. And so, it will make its trip all the way to cuba as a tropical storm. And not an incredibly strong tropical storm. But once it passes cuba and gets to the warmer waters of the gulf and curving towards florida, we have every indication it turns into a strong category 1, maybe a category 2. And now, the center of uncertainty is along the alabama coastline. That means everyone from houston all the way to the keys has to watch this storm system. Let me show you why tampa is not out of the woods yet. And why we're going live to matt soon, is because we've got the storm system. And many of the paths are cutting very close to tampa. Close enough that flooding could be a concern. Heavy rain could be a concern. And wind, as well.
