>> to turn to brian williams who joins us at the republican national convention site in tampa. brian, we both witnessed the devastation in new orleans firsthand seven years ago this week. you heard the mayor a moment ago. it sounds like these lessons are still very, very fresh in everyone's minds.
>> reporter: well, lester, it's hard to believe the timing of this. in plain english wouldn't it be nice if new orleans could catch a break. think of all the triggers as of tonight. the chopper pilots gog offshore rigs to bring loads of employees off the rigs onto land and repeating that all night tonight, all day tomorrow. now, this storm will encounter a different new orleans from years ago. on the downside a homeless population of 5,000 because of katrina. gabe mentioned the up upside, but where have we heard that brch before? the corps of engineers. this is the first test of a lot of new walls and gates and levees from seven years ago. this is worth repeating the water in the gulf olympic bathtub conditions, 83 degrees in some places. storms can explode over places like that. in plaquemines parish , st. bernard's parish and jefferson parish , it doesn't take much to bring a 6 to 8 foot storm surge . this is a good time indeed for new orleans and the region to catch a break. les.
