Now, to that major storm slamming into the U.S. Texas getting this, and much of the gulf. Dangerous winds and up to two feet of rain possible in some places by the time this is done. Rain and 70-mile-an-hour winds battering this airport in baton Rouge, tossing planes, flipping some upside down. And blinding rain causing a hazard in Houston. The region bracing for flash flooding and more than a half foot of rain still on the way. ABC's Clayton Sandell in galveston. Reporter: Imelda tonight is a slow-moving super-soaker. No longer a tropical storm, but still dumping heavy rain in southeast Texas, snarling the commute. And we've got some kind of a collision here on the side of the road. Reporter: More than half a foot of rain in neighborhoods near Houston's hoby airport. And in the barrier islands near freeport, up to 17 inches. In galveston, neighbors pitched in to help stranded drivers. This looks like a river. Reporter: The house where hank and Brittany holligshead live is now an island. It was like water out of a bucket. Just super, super hard rain. Reporter: In Louisiana, 65-mile-per-hour winds whipping through Baton Rouge, flipping several small planes. And David, you can see behind me here, this water has shut down a number of streets here in galveston. And this part of Texas is expecting another ten inches of rain by the end of the week. David? A real mess. Clayton, thank you. We're not only follow egg that storm, but there is a hurricane right off the east coast and other tropical threats in the pipeline. So, let's get right to chief meteorologist ginger zee tonight, tracking it all again for us. Hey, ginger. Reporter: David, all you have to do is look at that satellite image. There are five areas of interest in the atlantic alone. Jerry, Humberto. A couple of areas of interest. But tropical depression of Imelda is what we start with. I'm talking 15 to 21 inches from sergeant, Texas, to freeport. Look at those bands. They've had three-inch per hour rainfall rates. Now the flash flood watches extend to Shreveport, Louisiana. You could see six to ten inches on top of what you've already had. Then we go to Humberto. Just got a report in, bermuda had a 100-mile-an-hour gust. And Jerry, headed, looks like toward islands but looks like it's going to stay away. Most of the computer models curve it away from the united States. All that would mean, high surf going into early next week. We'll be watching. David? Ginger, thank you.
