AMANPOUR: Welcome to the program. We've got lots to get to today, but first, some news since your morning papers.
Tropical Storm Lee makes landfall this morning, as the Gulf Coast braces for impact. Lee is expected to dump 10 to 15 inches of rain on the region. And ABC's Yunji De Nies is in New Orleans with the latest.
Good morning, Yunji. And, of course, nobody can look at New Orleans without remembering Katrina. What's happening there right now?
YUNJI DE NIES, ABC NEWS: Well, the rain has been incredible. It started two days ago, and it really has not stopped. It's putting the levee system and the drainage system here to the test, although so far, everything has been holding. The wind has also been incredible, with gusts of up to 60 miles per hour. Ten tornadoes have touched down along the Gulf Coast, though, thankfully, no one has been injured.
We've seen quite a bit of flooding in low-lying areas. On some roads, people opted for boats instead of cars. This is supposed to be the final holiday weekend of the summer, but across the Gulf Coast, much of it has been spent working, because people have been sandbagging to protect their homes. There are also big concerns about storm surge.
Take a look at this boat in Pass Christian, Mississippi. Firefighters tried to tie it down, but the surf was just too strong.
Now, the winds on the ground here are incredibly fast, but the storm itself is very slow-moving, just two miles an hour. That will mean this region and this city will get exactly what it does not need today: more rain and possibly more flooding.
AMANPOUR: Yunji, thanks so much for being with us there in New Orleans and keeping an eye on that.
