I won't duplicate the efforts of
In addition to the list provided by
Second Harvest, the food bank network, not only had ten of its food banks and hundreds of related agencies wrecked by the hurricane, they are also coordinating efforts to bring critical food and water supplies to the region. If you feel more comfortable paying directly for critical food and water for the survivors and evacuees, rather than tossing money into the Red Cross's more general needs fund for Katrina, go here.
Any help you can give I'm sure will be appreciated.

ETA: Of all things, Editor & Publisher is maybe doing the best job I've seen in the newsmedia of covering Katrina from all angles. Coverage includes:
- on-the-ground blogging of rescue efforts
- how the local news media is adapting and cooperating to provide coverage, considering that some newspapers don't have offices right now (hell, the Times-Picayune can only publish on the Web; the newspaper is not publishing an actual newspaper right now)
- summary of Times-Picayune articles dating from 2004 warning about the long-term affect of cuts to the Army Corps of Engineers and the Southeast Louisiana Urban Flood Control Project (SELA). These cuts, btw, were used to fund Bush's tax cuts and the Iraqi boondoggle. (It should also be noted that I've seen reports that 35% to 40% of the Louisianna National Guard are currently now fighting in Iraq and are not available to do the jobs they actually signed up for, namely, keeping peace in their home states during emergencies.)
