As I noted here ThinkProgress has a timeline of Katrina. Check it out.

In addition to that, Talking Points Memo and This Modern World has been doing a bang up job of summarizing this and other Katrina news articles. You can see the last two week's worth of entries from TPM here and here and similarly for TMW here and here.
