There’s a website called scipionus.com that is a "mashup" of a wiki (an "open" website that allows users to add information themselves) and Google maps that allows people to input data about conditions at specific addresses on the map.

If you go to the site click on any of the balloons in an area you’re interested in, then zoom in.  You can see that people are putting in an address and then information like, "Wind damage, no power and no flooding.  Looting is rampant, pure anarchy."

As Steven Leavitt of Freakonomics describes the site:

"Surfing around, the devastation doesn’t seem as bad on the wiki as it
does on TV. Houses a block or two from Lake Pontchartrain with no
flooding, for instance. This shouldn’t be surprising. TV is only
showing us the worst. The people in good enough shape to be entering
info on the website are probably heavily selected towards those who
fared well. The truth is probably somewhere in between."
