These are some of the Infrared loops from Katrina before I decided to leave. They will each open in a new window if you right click and choose Open in New Window. On the upper left of the animated gif are the times each frame was taken in GMT. I have converted the times for you as the link for the animation. They are large files, a little over 1.5MB. A sample of a small plain IR file is at the bottom.

The IR picture below was taken 04:31 CDT Saturday, Aug. 27, 2005 from the Weather Channel site. It didn't look so bad then.
