There is an enormous amount of help information at the site

http://www.srh.noaa.gov/jetstream/doppler/radarfaq.htm Frequently Asked
Questions

In that help mode, the left frame has links to additional useful
information beyond the faq page about how to best use the site including
your cache.

Here's an example:

<q>
Why can't I loop radar images in the standard version with my dial-up
connection?

The looping images in the "Standard Version" radar display are animated
gifs. Web accelerator services that are designed to decrease your
download times do so by many methods, one of which is to compress graphics.

When an accelerator service compresses the radar loop, it essentially
keeps the oldest image (first in the loop) and deletes the remaining
images. To view the loop in the "Standard Version" you need to disable
the accelerator service to prevent this compression of the radar image.

Yes, the files are large and it will be slow on dial-up but the overall
file size, including the webpage and all graphics is typically much
smaller than the old original looping version (about 25% smaller).
