(1) A new page just went up on the website of the National Hazard Mitigation Association, dealing with the Moore, OK event and its aftermath.  The team has assembled a terrific list of resources on safe rooms and other related topics.

The Diva just joined the Association and urges others to do so too.

(2) The Institute for Building and Home Safety also has a number of useful resources, one of which is this tornado archive.

(3) American Society of Civil Engineers ( ASCE) also had a useful page of resources re Rebuilding After a Tornado. (Thanks to Chris Jones for this additional site.)
