Updated Aug. 30 at 10:10 a.m. ET: Tropical storm Isaac lost more steam as it lingered over land Thursday but was still expected to cause widespread flooding and rain as it moves over the center of the country in the next few days, according to the National Hurricane Center.
The storm knocked out power for more than 730,000 residents of Louisiana and Mississippi, according to Reuters, and some residents had to be rescued from submerged homes.

Updated Aug. 29 at 6:27 p.m. ET: While officials report that the multibillion dollar levees built in the aftermath of Hurricane Katrina around New Orleans have mostly held, the danger of Isaac has not yet passed. Downgraded back to a tropical storm Wednesday, the latest advisory from the National Hurricane Center warned Isaac was still "producing life-threatening hazards from storm surge and inland flooding as it moves slowly across southeastern Louisiana."
Across Mississippi, Louisiana and Alabama hundreds of thousands were without power and some were in need of rescue due to rising flood waters. CNN reports damages could top $1.5 billion. One death has been blamed on the storm so far. The LA Times has a slide show of the damage, rescues and heroism in Isaac's wake.
While widely reported to be nowhere near as powerful as Hurricane Katrina, NPR reports the president of Plaquemines Parish -- the area where Isaac made landfall in Louisiana -- deemed Isaac to be equally, if not more so, damaging than the hurricane of seven years ago.
"I don't know who's calling this a category 1, but this is no category 1," Billy Nungesser told NPR's Steve Inskeep on Morning Edition. "My house has more damage than it did during Katrina."
Updated Aug. 29 at 9:30 a.m. ET: Hurricane Isaac, still deemed a Category 1, moved steadily toward New Orleans Wednesday morning, whipping the city with rain and 80 mph winds, on its path from the Gulf of Mexico. We'll have more about the storm on the NewsHour broadcast. View the latest on Isaac on The Weather Channel's website.

On the eve of the seventh anniversary of Hurricane Katrina and with sustained winds of 80 mph, the center of Isaac was 105 miles south-southeast of New Orleans and was on a relatively slow path towards the city -- about eight mph -- according to the latest advisory by the National Hurricane Center.
