>>> The Federal Emergency Management Agency creates daily National Situation Reports covering important weather- and disaster-related issues. A number of people requested the "sitreps" for the time period of Hurricane Katrina and its immediate aftermath, and FEMA at one point posted them to its FOIA Reading Room. They are now gone. Searches of the FEMA website and the Department of Homeland Security website come up empty. Here they are, in one zip file above (note that several days were missing in the original release, which needs to be looked into separately). And here's the Internet Archive page where I've housed them.
